The technical field

The present invention relates to a disposable diaper, in particular to disposable opening the diaper, which is worn by gearing sasagawa tape or sticky traps at the edges on both sides or the rear side or front side, with gearing located between the edges on both sides of the respective front side or rear side.

The level of technology

Well-known disposable diaper of open type, which includes permeable to liquid face layer that is impermeable to the fluid in the rear layer and the absorbent main part located between them, and it is worn by fastening sasagawa tapes located at the edges on both sides back to sasagawa portion located in a predetermined location on the front side.

For a disposable diaper of this type choose as zastarevshego mechanism sasahivi mechanism type hook and loop, where all zastarevshy tape or part of it turned into Krutoy element fastener type hook and loop on the pre-defined location of the front side part of the waist in the direction of the width, layer, hinge element fastened to the education section of the gearing, and Krutoy element is pressed and Zats what is to fasten looped element, which is the site of the engagement.

More recently became known another disposable diaper of open type, which is selected by the mechanism of a fastener type hook and loop, called the target tapeless, in which no education site engagement by fastening the hinge layer of non-woven layer is formed of the outer surface of the back layer and the front side part of the waist back layers formed by embossing in the direction of the width for turning the rear layer in the area of engagement that is known.

In a disposable diaper, for which the chosen mechanism fastener type hook and loop, like this one, even after repeated sestigiani and rasstegivanie when wearing, really unlikely to deteriorate force engagement, and it fastens with a corresponding shear force to be wonderful to wear.

On the other hand, in a disposable diaper, for which selects the closure type hook and loop, the main thing is that to respond to user movement of the valve, which sealed sasagawa tape, attached elasticity, essentially sasagawa the ribbon attached to the elasticity, or forming area of the engagement region is ensured by the elasticity for imparting elasticity around the waist part d the I formation it thus, so the user can easily move. In addition, in no particular giving of elasticity, such as this, due to the elongation and the like comprising a layer of material that accompanies the movement of the user surrounding the waist part significantly expands and contracts.

However, the area of engagement of the existing disposable diaper is formed so that the force of separation from krachodnok element is not varied depending on the region. Accordingly, when, for example, sasagawa tape engaged by attraction to the Central part so that the wear was slightly dense, stress reduction or similar sasagawa tape works stronger, to be a branch. On the contrary, when sasagawa tape is fixed with the location, close to the side so that the wear was slightly free, stress reduction sasagawa tape really hard work to lead to engagement with a force that is not necessary.

In the configuration for persistence gearing, a necessary and sufficient condition, when drawn surrounding the waist part, only problem, if it turns out stronger force of separation between sasagawa tape and the layer of hinge element and the embossed region, which forms the plot of engagement, or SaaS is avivausa tape or side valve are formed by stretching, to loosen the tension surrounding the waist part. However, in the aspect, when the force of separation is obtained stronger, zastarevshy tape is difficult to re-fasten again, this is a disadvantage compared with the advantages of a fastener type hook and loop. On the contrary, when the tensile stress surrounding the waist part comes out weaker, front and rear main parts tend to move, causing the flow.

In addition, depending on, for example, from the shape of the waist part, due to age or frequent movements, such as bending or the like, the front and rear main parts often cause displacement. At the same time sasagawa tape often exfoliate in the direction of the length of the product. Accordingly, at the same time, the width of the moving front and the rear of the main parts is greater at the edges on both sides in the width direction than in the Central part in the width direction of the product, respectively, is desirable products, where the edges on both sides in the width direction is more difficult to peel than the Central part in the width direction of the product.

Now clasp type hook and loop element is gearing where the layer of hinge element having hinge elements obtained through education of the fiber loop and the and arc and layer krachodnok element having a pile Krutoy element having the convex shape of the top, such as the shape of a hook or form of fungus, which engages with the hinge elements, squeezed and engaged to provide a strong adhesive force. Closure type hook and loop, easily fastened and rasstegivaemoy and with a suitable force engagement, as mentioned above, is used in various fields as zastarevshego element or similar disposable diaper or the like.

Traditionally, the layer of hinge element fastener type hook and loop formed by the improved hinges and the like through the use of needle punching, spun, gidrobotanika or thermal compression to the non-woven fabric, which utilizes fiber synthetic polymer, such as nylon, polyester or similar.

In the layer of hinge element containing a synthetic polymer fiber, for regulating the engagement and efforts to contain fibers from rising, the hinge element is partially melted by passing through a heated roll with a pattern or roll with embossing.

However, when the hinge element is partially melted to regulate the efforts of the engagement such as this, the layer of hinge element hardens into melted the Asti. Accordingly, when the hinge layer, similar to that used in the product, which comes in contact with the skin, such as a disposable diaper, is the negative feeling of rigidity. In addition, so as to produce the required heat source, consumes large amounts of energy, resulting in increased cost of production.

In addition, if you change the design drawing rolls should be changed, thus changing the design is disadvantageously difficult to apply.

In addition, when processing the melt is applied once, the force of engagement after it is not restored, respectively, is impossible to construct so that the force of engagement could be limited to only when there is no need to link.

Disclosure of invention

In this regard, the present invention is intended to provide 1) a disposable diaper of the open type, which can always be hooked with proper effort, wherever zastavivhsee location sasagawa tape in relation to the area of engagement, 2) disposable diaper provided with a closure type hook and loop, in which without rspl the effect of the fiber by heating and without partial curing, the force of engagement can be adjusted, you can easily apply the change of design and effort gearing can be limited only to the time that is not necessary, and 3) in the target tapeless disposable diaper, in particular disposable diaper, in which the force of engagement is improved without an accompanying significant changes to the design of the rear layer and sasagawa tape.

Below the present invention will be described with the solution to the above problems.

<the Invention under item 1>

Disposable diaper of open type, which includes: permeable to liquid face layer; impervious to liquid back layer; and an absorbent main part located between them, in which zastarevshie tape are placed on the edges of both sides of any one of the rear side or front side, sasagawa tape partially or completely formed from krachodnok element fastener type hook and loop, and Krutoy element engages for wearing with a plot of gearing located between the edges of both sides of the front side or rear side, characterized in that

plot gearing is located so as to extend from the center in the width direction of the product towards the edges on both sides and force separation from krachodnok element is formed so as to vary stepwise or continuously from the center is the real part in the direction of the width of the product in the direction of the edges on both sides and/or from one side in the vertical direction of the product towards the opposite edge.

(Action and Result)

When the segment gear is located so as to extend from the center in the width direction of the product towards the edges on both sides, the area of engagement is formed wide for the front and rear sides of the user, respectively, the operation of the gearing is easy.

In addition, the area where Krutoy element engages on the site of engagement, it is a Central part in the width direction, which is usually located at the farthest location where the engaged position easily and unintentionally cancelled due to tension in the direction of the edges on both sides sasagawa tape under the influence of environmental pulling the waist part after engagement or movement of the user and under the influence of the shape of the user's body.

On the other hand, at the edges on both sides in the normal state, the engagement is not often inadvertently cancelled due to the tension like this. However, depending on user movement front and rear main parts often are moved, respectively, in the aspect where this situation occurs frequently, the state of engagement tends to cancellation more on the edges on both sides in the width direction than in the Central part in the direction of the width of the articles the Oia.

Accordingly, in the present invention the area of the mesh can be formed so that the force of separation krachodnok element could vary stepwise or continuously from the Central part in the width direction of the product towards the edges on both sides. That is, the division can be set to lower or increase stepwise or continuously from the Central part in the width direction toward the edges on both sides.

Set whether the power is split so as to increase or decrease, can be constructed depending on the age or aspects of wearing the intended user. For example, if it is a product during the period where the movement is small, like a child, because of the division can be a favorable way to make low from the Central part toward the edges on both sides in the width direction so that the Central part can tightly hold in the direction of the width of the product, in which the engaged position is most likely to kill because of the tension surrounding the waist portion or the like, and the edges on both sides, if there is no need for strong engagement, could favorably stick or delaminate. For example, if it is a product for baby, on the contrary, the power p is selenia can favorable way to do the above from the Central part toward the edges on both sides in the direction of the width.

When the division make below or above towards the edges on both sides, because of the division it is possible to lower the speed for each particular interval or continuously.

In addition, the area of engagement of the present invention can be formed so as to effect separation from the hinge element can be differentiated stepwise or continuously from one edge in a vertical direction toward the opposite edge of the product.

Partial differences in the magnitude of the force of separation can be suitable to construct depending on the age of the intended user, or facet wear. For example, when the product is intended for the baby, whose upper part of the waist (the periphery of the navel) to a greater extent is allocated, it may be beneficial to the strength of the division was higher from the Central part toward the upper side in the vertical direction, so that it is tightly caught in the vicinity of the edges surrounding the waist opening, where the engaged position, the most likely cancelled due to abdominal pressure and in the lower part of the waist, if you don't need strong engagement, it is easy to engage or disengage the clutch. When it is a product for adult is a person whose lower part of the waist are highly favored, on the contrary, the division can be favorable about what atom to make higher from the Central part toward the lower side in the vertical direction.

In addition, in the area of engagement of the present invention can be combined differences in forces engagement in the width direction and the vertical direction. For example, in a product for a child, because of the division between the area of the mesh and looped element can be done from above the Central part in the width direction toward the edges on both sides and from the Central part toward the upper side in the vertical direction.

<the Invention is in p. 2>

Disposable diaper under item 1, in which the area of the clutch is formed by bonding a layer of looped elements fastener type hook and loop, where the back layer is formed lots of looped elements.

(Action and Result)

Without changing the configuration of the main part of the diaper by means of a suitable design of the layer of hinge elements can be used to form the plot of the mesh, where the force is gearing partially different.

<the Invention is in p. 3>

Disposable diaper under item 1, in which the protective layer itself is partially converted into a plot of engagement.

(Action and Result)

In the present invention, the back layer itself can be partially converted into a plot of engagement. For example, when the outermost layer of the back layer made of nonwoven material through education looped elements the and part, which engages Krutoy element, formed a plot of engagement. This aspect is also called the target tapeless. As a method of education section of the mesh, you can select a suitable method such as a method of stamping, the method of the corrugation or the way of Napping needles.

Now, when the selected method of stamping, by differentiation of the depth or density of stamping can be easily differentiated because of the division. For example, when using the embossing, the hinge element razravnivaetsya. Depending on the degree of crushing varies the power of the division. The deeper or thicker apply embossing, the more razravnivaetsya hinge element, which leads to reduction in force separation of this part. Accordingly, in case the target tapeless, where the external surface of the rear layer is formed from a fibrous layer such as a nonwoven layer or the like, by stamping coarser or deeper in depth from the Central part toward the edges on both sides, can be differentiated because of the division.

<the Invention on p. 4>

(Action and Result)

<the Invention on p. 5>

Disposable diaper under item 3 or 4, in which the layer of hinge elements or the back layer, which forms the plot of engagement, are embossed and embossed pattern is the pattern along the machine direction or the transverse direction.

(Action and Result)

When the embossed pattern is located along the machine direction or transverse direction, Napping of flannel fibers caused by peeling sasagawa tape decreases. In this case, the machine direction is the anteroposterior direction of the product, and the transverse direction is the direction of the width of the product.

<the Invention on p. 6>

Disposable diaper according to any one of p. 2 to 5 inclusive, in which the area of engagement is:

hinge layer that has a configuration where forming the hinge element surface layer OS is Finance loops, where there are a lot of loop elements, is placed a perforated protective layer having a number of holes, and sealed for engagement with Kruchonykh element after forming the hinge elements of the surface, the remaining unprotected from the holes of the perforated protective layer, or

part, which is configured so that the interval containing the hinge element, which are formed by themselves, many hinge elements formed fiber rear layer, was covered with a perforated protective layer having a number of holes through which the hinge elements of the surface, the remaining unprotected from the hole engaged with Kruchonykh element.

(Action and Result)

In the present invention, the power of engagement is very easily controlled only by varying the size, number and pattern of the holes of the perforated protective layer. In addition, because the base of the hinges having hinge elements, or looped main part is not melted, for regulating the adhesion forces there is hardly a hardened part in a wide interval. In addition, it also does not require as much heat.

In particular, when the base of the loops is a nonwoven material as cheaply obtained hinge layer, the value of mo is but to lower.

<the Invention under item 7>

Disposable diaper under item 6, in which the perforated protective layer is sealed through a hot-melt adhesive layer to the base of the loops or the back layer.

(Action and Result)

By applying the hot-melt adhesive without the hardened part can fasten both layers.

<the Invention under item 8>

Disposable diaper under item 6 or 7, in which the perforated protective layer has an elasticity and partially sealed with a layer of the base of the loops or the back layer can be formed in the corresponding holes with the change in size due to expansion and contraction of the perforated protective layer.

(Action and Result)

In the present invention, holes are formed by changing the size of the flexible perforated protective layer. Accordingly, the protective layer may be extended upon application for engagement with Kruchonykh element in a state where the holes expand, and when there is no need to engage in a state where the perforated protective layer is reduced, holes are made smaller, to get the remaining exposed part of the lower. Thus, the force of engagement is constrained over time, which is not necessary, and the power of engagement is driven within the required time.

Especially predpochtitelno, to perforated protective layer had flexibility with firmness.

<the Invention under item 9>

(Action and Result)

In the present invention between the base of the loops or the like and a perforated protective layer is an elastic material with elasticity. Accordingly, when the elastic material is reduced, the base of the loops or the like is reduced to cause the folds to hide the holes between the folds, and when the elastic material is stretched, holes are set to appear between the folds. Accordingly, it is possible to form so that after Krutoy item caught in a state where holes are shown in the course of stretching, lengthening krachodnok element or similar canceled again to hide in the folds of holes that are not necessary for the engagement.

<Invention by p. 10>

Disposable diaper according to any one of p. 6 to 9 inclusive, in which the perforated protective layer is provided with many looped elements for zatepleni is with Kruchonykh element, formed on the outer surface side of the diaper.

(Action and Result)

As forming a hinge element surface exposed holes of the perforated protective layer, and the hinge elements perforated protective layer themselves engage with Kruchonykh element, respectively, in General, increases the power of engagement. The force of engagement is governed by the rate of formation of holes. When the material of the base layer of loops covered with a perforated protective layer, and the material of the perforated protective layer differ in the strength of the division, you can more effectively regulate the force of the engagement.

<the Invention according to p. 11>

Disposable diaper according to any one of p. 2 to 10, inclusive, in which at least one of the predefined ranges established as the site of engagement of the layer of hinge elements, the base of the loops, perforated protective layer and back layer, each of which has a hinge elements located many penetrating holes.

(Action and Result)

Krutoy element sasagawa tape engages with many holes, respectively, can increase the force of engagement. In particular, even if not voluminous non-woven material having a low density, with the AMB sufficient force engagement. The force of engagement with sasagawa tape can be adjusted by the rate of formation of holes.

<Invention by p. 12>

Disposable diaper under item 11, in which the holes are formed by applying the operation of the opening-side surface which is the inner surface side of the diaper in the direction of the side surface which is the outer surface side of the diaper, and the edge of the hole sticking out.

(Action and Result)

As the edge of the hole sticking out even a little, become easy engagement for Kruchonykh elements, thus, it becomes easy impact on force engagement.

The results of the invention

As described above, in accordance with the present invention it is possible to provide a disposable diaper of the open type, in which any part of the plot gearing is used for fastening, it is always possible that the state of engagement has suitable strength, especially in the Central part, where the gearing will probably be cancelled under the influence of the tension surrounding the waist portion can firmly catch, while at the edges on both sides, which are less exposed to the risk of cancellation, engage not excessively strong.

In addition, it is possible to provide a disposable diaper provided with a mechanism for whom Tiki type hook and loop, in which without the necessary fusion of the fibers by heating and without partial curing, it is possible to adjust the strength of the engagement, it's easy to change the design and strength of engagement can be limited only for the time that is not necessary.

In this document, in the present invention or the patent description, because the method of measurement does not change when the dimension of the relevant parts of the plot gearing, the method of measuring the strength of separation is not particularly limited. In short, the method of measurement is sufficient to be able to measure the force when Krutoy element and the hinge element off after their bonding. Especially preferred method of measuring the strength of separation will be described below.

In addition, in the patent description easy cancellation gearing sasagawa tape from the site of engagement in the state of wearing sometimes refers to the force of the engagement.

The best way of carrying out the invention

Next, with reference to drawings will be described in detail ways of implementation of the present invention.

[The first Version of the Implementation]

Fig. 1 shows fastened disposable diaper Z1 in accordance with the first embodiment of the present invention. Disposable diaper Z includes permeable the liquid front layer 11, located on the side toward the skin of the user, impervious to the fluid in the rear layer 12, which is located on the outer side of the product and is essentially impervious to liquid, and absorbing the main part 13, which is located between them, is rectangular or preferably the shape of an hourglass and has a certain degree of rigidity, in which the edges on both sides of the rear side are arranged for fastening zastarevshie tape Y1 and Y2.

zastarevshie tape Y1 and Y2 are formed, except for the parts that are bonded to the edges on both sides and upper parts, which are parts of the loops, from krachodnok element fastener type hook and loop, and the area of engagement X1, which engages Krutoy element located on the outer front side of the rear layer 12.

The back layer 12, forming the main rectangle that is wider than the absorbent core portion 13, and is provided on the main Central part in the longitudinal direction around the leg parts formed cut edges in the form of an arch on both sides, and is formed by laminating the outer nonwoven layer 12V to improve the texture of the outer surface of layer 12A is impervious to the liquid film, such as polyethylene film or the like, with subsequent compression of the bond by a process of stamping or the like, suffered through a hot-melt adhesive. The outer nonwoven layer 12B is formed so that it had a dense fibrous loops or dense fibrous arch so as not to engage with Kruchonykh element. In the embodiment, it is not necessary to place the nonwoven layer, that is, the back layer can be formed only from a layer impermeable to the liquid film.

In this document the rear layer 12 preferably be formed so as to have a moisture permeability in the range of from 0.5 to 4.0 g/100 cm2h, and the layer 12A is impervious to the liquid film and the nonwoven layer 12B preferably be bonded so as to have the force of separation in the range from 115 to 135 g/25 mm Force of separation is the force of separation of 180°when in the conditions of 25°C and a relative humidity of 65% of the back layer 12 represents a sample with a width of the original fabric, equal to 12 mm in the width direction (horizontal direction)and a length of 100 mm, with subsequent isolation from one end at a rate of 300 mm/min

As a layer 12A is impervious to the liquid film applied to the back layer 12, without any limitations, you can apply a layer known impermeable to the liquid film, which is used as the back layer 12 of absorbent products. Its specific examples include various types of synthetic polymeric layers, such as politi envy layer, polypropylene layer, a layer of polyurethane, polyethylene terephthalate layer or the like, and porous layers of synthetic polymers obtained by the location of many small inlet or outlet to give a synthetic polymer layers breathability. The thickness and stiffness of a layer impermeable to the liquid film can suitably be selected in accordance with known criteria, taking into account the thickness and stiffness of the nonwoven layer that you want to laminate.

As a non-woven layer used in the back layer 12, it is possible to apply the well-known non-woven layers, used as the back layer of absorbent products. Their examples include non-woven material formed through appropriate processing of a cloth made of a synthetic polymer such as an olefin, including polyethylene, polypropylene and the like, polyester, polyamide and the like, recycled fibers, including rayon, copper ammonia fiber and the like; and natural fibers, including cotton and the like. They are made by an appropriate process, such as how Hydrobotany, how sprzedania, the method of thermal bonding, spunbond-inflatable method, method of needle punching of holes, the method of heat shrinkage and the like.

On the basis of technological ways is s, how hydromotive gives excellent elasticity and property Dragonheart and method of thermal bonding provides excellent volume and softness accordingly, they can appropriately be selected depending on the object. In this document, the nonwoven layer may be laminated non-woven layer. For example, as starting material can be applied nonwoven laminate obtained through appropriate laminating two or more layers of the layer of spun nonwoven material (S), where the fabric is formed by way of sprzedania; and a layer (M) inflatable non-woven fabric, where the fabric is formed in accordance with spunbond-inflatable method.

On the other hand, the area of engagement X1 is formed by bonding a layer of the base of the loops from the back layer 12 by using the hot-melt adhesive. Plot gearing X1 is located on the front side of the product, being extended from the center in the width direction of the product to the edges on both sides. In the illustrated example, the area of the mesh is formed as a desirable shape as a rectangle, an elongated horizontally, but he is not particularly limited to a rectangle. You can take other forms. Can favorably to apply suitable known method, the corresponding hinge element, as a way of fastening the rear layer 12.

In this document the site gearing X1 variant implementation is characterized in such a configuration that the power split between zastarevshie ribbons Y1 and Y2 and Kruchonykh element may change stepwise from the Central portion in the width direction of the product towards the edges on both sides. In the illustrated example, the area of engagement X1 is divided into 5 zones, as shown in Fig. 2 the relationship between area and power division power division is formed so that the area D1, located in the center, could be the highest, and on a point of order in the zone D2 adjacent to it and in the zone D3, next adjacent to it, the force of separation may be reduced. A particular strength of the separation of the respective zones can determine accordingly and, generally, it is desirable that the power of the division were distributed speed difference is essentially in the range from 100 to 1500 Gauss, especially from 140 to 400 Gauss. When the force of separation is less than 100 Gauss, 't enough gearing, and when the power separation exceeds 1500 GS, since the force of engagement is extremely strong during engagement and disengagement, a piece of gear has a tendency to the formation of the pile.

The method of measuring the strength of the division is carried out as shown below. At the beginning of a fabric tape having a width of 50 mm and a length of 100 mm, bend in half in the direction of the width d is I the education of the bent twice tissue tape, having a width of 25 mm and a length of 100 mm, and one end of the fabric tape is firmly attached zastarevshy tape. At the same time Krutoy element sasagawa tape is placed so that it was located outside of the upper end of the fabric tape.

On the other hand to stainless flat plate, attach the hinge element in accordance with the present invention by applying a bilateral adhesive tape forming the hinge element surface which is saved as the top surface. In addition, both ends fixed craftool tape.

Then after Krutoy element and forming a hinge element surface is brought into contact, the roller having a mass equal to 2 kg, once moving them back and forth from the side tissue tape to compress and attach sasagawa tape and hinge layer. In addition, at the other end side opposite to the side where the joins sasagawa tape, tissue tape, for 10 sec suspended mass of copper equal to 1 kg, for the application of shear force to the compressed and attached parts to ensure engagement.

After this stainless flat plate and the other end on the side opposite to where joins sasagawa tape fabric tape is clamped by a clamping device breaking machine. At the same time the direction of elongation of the mounting bracket, which clamps the other end on the side opposite to where joins sasagawa tape, tissue tape, set at 90° to the stainless steel flat plate.

Thus, after the clamping device is set to a tensile testing machine so that the final angle of exfoliation could be 90°, compressed and attached part prepare the chin with a speed of 300 mm/min, and the bulk of the upper and lower values measured in this case, is selected as the force of separation. The measure is expressed through a medium from 3 to 10 effective dimension values. In addition, when the measurement sample is set to a dimension in the transverse direction compared to the transverse direction. Also, considering the size of the test specimen, Krutoy element mounted on 47 mm ± 3 mm (machine direction) × 93 mm (transverse direction) and the base hinge set 23.5±1.5 mm (machine direction) × 24 mm (transverse direction). In this document, the machine direction is the anteroposterior direction of the product, and the transverse direction is the direction of the width of the product.

When testing the effect of separation, you can apply a tensile machine (trade name: AOUTGRAPH AGS-G100N, manufactured by Shimadzu Corporation).

On the other hand, count the number of zones section of the gearing without limitation five zones, as illustrated, may be 3 or 5 or more zones. However, because the division is set to reduced speed zone preferably has a size where you can put Krutoy element formed on sasagawa tape.

In the embodiment, between the zones located on the line symmetrically to the Central line in the width direction of the product, the forces of separation are formed so that they are identical. However, it is not necessary that they are identical.

In addition, like the relationship between the strength of the separation and location of the area of separation, shown in Fig. 3, without the formation of zones, the division may be formed so that it is continuously decreased from the Central part in the width direction of the product towards the edges on both sides.

In addition, the area of separation X1 regardless zones, it is desirable to design so that the shearing force with Kruchonykh element sasagawa tape could be from 1 to 10 kg and preferably from 3 to 8 kg When shearing force is less than 1 kg, it is likely that the engagement is cancelled. On the other hand, when the shear exceeds 10 kg, the gearing is too strong.

Shearing force is measured, as shown below. First in a stainless steel flat plate, the hinge layer ACC is accordance with the present invention attached by applying a bilateral adhesive tape forming the hinge element surface, installed as the top surface. In addition, both ends fixed by applying craftool tape. At the same time on the periphery of the base layer loops leave the edge of the stainless steel flat plate.

Then after Krutoy element sasagawa tape is brought into contact with the forming crocosmia elements surface, the roller having a mass equal to 2 kg, once moving them back and forth from the side tissue tape to compress and attach krachodnok element layer and the base of the loops.

After that, the protruding part of the stainless steel flat plate and one end sasagawa tape is clamped by a clamping device breaking machine. At the same time, the distance between the clamps mounted on 50 mm After clamping is coming to an end, the clamping device is tightened in the direction of the shift krachodnok element and base layer loops with speed tension equal to 30 mm/min, to measure the maximum shearing forces. The measure is represented as the average from 3 to 10 effective measurements. In addition, when the measurement sample is set to a dimension in the transverse direction compared to the transverse direction. Also, considering the size of the test specimen, Krutoy element mounted on 47 mm ± 3 mm (machines the first direction) × 93 mm (transverse direction) and the base hinge set 23.5±1.5 mm (machine direction) × 24 mm (transverse direction). In this document, the machine direction is the anteroposterior direction of the product, and the transverse direction is the direction of the width of the product.

On the other hand, the hinge element fastener type hook and loop, which forms the plot of engagement X1, formed from such sheet material, provided with hinge elements suitable for engagement with Kruchonykh elements located on sasagawa tapes Y1 and Y2. You can apply various known types of Foundation layers of loops in existing examples through appropriate application of technology or similar.

As the hinge layer can be listed woven material on one surface on which is formed a variety of hinge elements in the form of loops or arches, non-woven material on one surface, on which many hinge elements in the form of loops or arches, obviously, is formed through the application of appropriate technological method such as the method of Hydrobotany or similar, to a cloth made of synthetic fibers, recycled fibers, natural fibers, such as cotton or the like, and a layer obtained by bonding the above non-woven material with the main layer.

In this document, as mentioned above, when the power split is differentiated stepwise or continuously between zones plot gearing X1, for example, you can use the hinge element, which varies the density of the hinge elements in each zone. Alternative such differentiation can be achieved, for example, by stamping a single hinge layer in each zone so as to properly crush the hinge elements.

On the other hand, Krutoy element fastener type hook and loop, which forms part or all zastarevshie tape Y1 and Y2, is formed from krachodnok layer having fleecy crocosmia elements, such as exposed tops in the form of hooks or mushroom shape, which engage with the hinge elements of the hinge element, which is applied at the area of engagement. As a method of obtaining sasagawa tapes from krachodnok layer, you can apply the known method without limitation. In addition, the size and density of fleecy Kruchonykh elements such as exposed tops in the form of hooks or mushroom shape, can also be favorably respectively to choose in this interval, so that you can get appropriate because of the division in connection with the hinge element.

On the other hand, although not shown in the drawing, a disposable diaper Z1 variant implementation with many elastic rubber threads with elasticity, spaced elongated between zastarevshie flax is AMI, is formed so as to be stretched or constricted between zastarevshie ribbons Y1 and Y2 on the rear side. Thus, sasagawa valid area sasagawa tapes Y1 and Y2 during fastening expands and thus sasagawa valid area due to different body shapes of users expands. In addition, due to such stretching and contraction improves the feeling of the fit while wearing.

Alternatively, you can choose to stretching and contraction of a disposable diaper between zastarevshie ribbons Y1 and Y2 on the back side was not out of rubber thread, but instead were chosen configuration, where between the upper part of each sasagawa tape Y1, Y2, and its main end part was placed corresponding elastic element, such as an elastomeric layer or the like on the upper end side in relation to placed an elastomeric element for extension and retraction were placed Krutoy element fastener type hook and loop itself sasagawa tape Y1, Y2.

In addition, it is also possible to adopt a configuration where between the so-called side valve part to which it is attached sasagawa tape Y1, Y2, and another part, put an elastic element, such as an elastomeric layer or the like, to allow stretching and contraction between tegevuse ribbons Y1 and Y2 on the back.

Also in these cases, improve the sense of fit and the allowed interval for the differences in body shape.

Tensile forces rubber thread and an elastic element can be constructed without problems inside the interval, valid known disposable diaper.

On the other hand, in the embodiment, the front layer 11 has a form identical to form the back layer 12, is extended outward beyond the outer part of the absorbent main part 13 and fastened to the back layer 12 using a hot-melt adhesive or the like. As the front layer 11 can be applied, in addition to various types of nonwoven materials, such as spun non-woven material, aerodynamic non-woven fabric, SMS non-woven fabric, point-bonded non-woven material or the like, within the interval where it is possible to guarantee the permeability of plastic film such as polyethylene film or the like, and laminated non-woven fabric obtained by laminating the plastic film and nonwoven material. In addition, you can also apply satapathy material obtained from plasmasprayed filaments of nylon, polyethylene terephthalate or the like.

Absorbent core portion 13 is formed of a fibrous structure, which is made from fiber accumulating soft mass or tow, to ora includes absorbent polymer and which is coated with a layer of soft masses or similar. As the fibers of the fibrous structure (hereinafter referred to in this document simply referred to as constituting the fiber tow) can be listed polysaccharides or their derivatives (such as cellulose, esters of cellulose, chitin, xanthone and the like), synthetic polymers (such as polyethylene, polypropylene, polyamide, polyester, polylactide, polyvinyl acetate and the like) and the like. Of them, particularly preferred are esters of cellulose and cellulose.

Preferred examples overabsorbed polymers include carboxymethyl cellulose, polyacrylic acid and their salts, crosslinked products of acrylate polymers, graft copolymers of starch and acrylic acid, hydrolyzed products of graft copolymers of starch and Acrylonitrile, crosslinked products of polyoxyethylene, crosslinked products of carboxymethyl cellulose, polyethylene oxide, partially cross-linked products nabukenya in water of the polymers, such as polyacrylamide or the like, copolymers of isobutylene and maleic acid and the like. Each of overabsorbed polymers can add a blocking inhibitor to limit the blocking properties caused by moisture absorption of the product. Each of these overabsorbed polymers has various forms such as powder form, the particle shape, a granular shape, preformed the Orme, ash form a slurry form, gel form, the form of film, the shape of the nonwoven fabric and the like. All these forms are applicable in the present invention, it is preferable to form particles.

The absorbent product of the present invention is not limited to the above configuration of this variant implementation. For example, it is possible to adopt a configuration where the elastic elements with elasticity, such as rubber threads or the like, traditionally used in a disposable diaper or the like, are located in different parts of the absorbent product. You can also apply a different configuration in which the second layer is located between the outer layer and absorbent core part of absorbent products for dispersion physiological fluid or similar.

[Second Variant Implementation]

In the first embodiment, as the site of engagement X1 sasagawa tapes Y1 and Y2 hinge layer fastened to a rear layer. However, in the second embodiment, so-called target tapeless, where not bond to the hinge layer to the back layer, and the outer surface of the rear layer 12 itself is partially accordingly is embossed for the formation of the hinge element to apply it as the site of engagement X1. Ignoras the new diaper Z2 in accordance with the second embodiment shown in Fig. 4. Next, the second option will be explained, mainly, by the description of the moments that differs from the first variant implementation.

There is no need to require that the rear layer 12 in accordance with the first embodiment was disposed outer nonwoven layer 12B. However, in the second embodiment, to improve the texture and education section of the non-woven mesh layer 12V or woven layer is always located on the outer surface side.

To bond the non-woven layer 12V and layer 12A is impervious to the liquid film compression and joining is conducted by way of stamping or the like through a hot-melt adhesive.

The mass per unit surface of the nonwoven layer 12B is preferably from 10 to 100 g/m2and more preferably from 20 to 60 g/m2. When the mass per unit area of nonwoven material is less than 10 g/m2the space where engaged Krutoy element is not completely preserved, and when exfoliates sasagawa tape, non-woven layer is destroyed. On the other hand, when the mass per unit surface area exceeding 100 g/m2productivity of non-woven material deteriorates, and the fastening sasagawa tape to the part that is different from the site of engagement, becomes negatively noticeable.

On the other side is s, on the back layer 12 variant implementation in the interval containing the interval, where is formed a plot of engagement X1, between the outer non-woven layer 12V and layer 12A is impervious to the liquid film is located intermediate nonwoven layer 12C. When placed intermediate nonwoven layer 12C, the corresponding portion becomes bulky, which is great for the feeling of penetration, when zastarevshie tape Y1 and Y2 are compressed and held together with a plot of engagement X1 and the peeling force is improved to prevent the exfoliation of the outer nonwoven layer 12, when zastarevshie tape Y1 and Y2 are bonded or peel.

In this document layer 12A is impervious to the liquid film and the nonwoven layer 12B in the intermediate section intermediate nonwoven layer 12C is desirable to seal so that the force of separation could be from 175 to 195 g/25 mm Force of separation is the force of separation of 180°when in the conditions of 25°C and a relative humidity of 65% of the back layer 12 represents a sample with a width equal to 12 mm in the width direction (horizontal direction), the original fabric and with a length of 100 mm, with subsequent isolation from one end at a rate equal to 300 mm/min

When the education section of the gearing X1 take way stamping, embossing is applied in accordance with the known method the m For example, after it turns out the rear layer 12, to a device for stamping, is provided with a convex embossed roller in a predefined location in which is formed a convex embossed pattern, and a rubber roller with elasticity to the extent in which fits the convex part of the convex embossed roller, addressed to him, the back layer may favorably be made so that the side nonwoven layer could be a party to the convex embossed roller for embossing.

In addition, you can use the device for stamping, is provided with a concave embossed roller, on which is formed a concave portion corresponding to a convex part of the convex embossed roller.

Also plot gearing X1 variant implementation is available with 5 zones, different power splitting, similar to the first embodiment. The difference in the power of the separation between the zones varies in accordance with the density stamping. For differentiation, you can apply the embossing depth.

What is accepted embossing depth or density stamping, depends on the density of the nonwoven layer and the configuration krachodnok element. You can apply the appropriate design. In this document as an embossed pattern, endowed with the properties section of the gearing, you can apply the ü-known figure, usually applied to this target tapeless type, and preferred is a drawing where the embossing is located along the machine direction or the transverse direction defined during the formation of the back layer. In this figure, the embossing is usually located along the longitudinal direction or the width direction, which is determined during the formation of the products and thus, you can get a similar product that is less fuzzy that could be caused by the engagement and disengagement sasagawa tape.

Although, in particular, are not shown in the drawing, when the embossing is located along the longitudinal direction of the product, elasticity and permeability environmental waist part are great. Herein in the present invention it is not necessary that the location along the longitudinal direction of the product was limited to a direct linear embossing, enables even the lettering, which is formed zigzag in the longitudinal direction of the side of the product. In addition, although not shown in the drawing, is also included embossed pattern in the form of an ellipse, in which the main axial direction is along a longitudinal direction of the product. There is no problem, since the longitudinal direction of the embossing runs along the longitudinal direction of the product.

[Third Varian Is Implementation]

Disposable diaper Z3 in accordance with the third embodiment shown in Fig. 5. In the disposable diaper Z3 in accordance with the third embodiment plot gearing X1 is derived from the design of many pieces of gear x, x .... the Elements of the mesh, x, x ... formed by the miniaturization of the hinge layer closure type hook and loop. Plot the mesh is formed from 5 zones, differing in the size of elements of the mesh, x, x .... In the area D1, located in the center, apply the most large elements of the gearing, and thus, the force of separation is set very high, the dimensions of the elements of the gearing used in zone D2, adjacent to D1, and in the zone D3 adjacent to D2, respectively, are smaller in this order, and thus, the area of engagement is formed so that the force of separation could be reduced towards the edges on both sides. The plot of the mesh can be formed so that the sizes of the elements of the mesh, x, x ... installed the same in each of the zones and due to the difference in density can be differentiated because of the division with Kruchonykh element in the respective zones. Other configurations are the same as the configuration of the first variant implementation.

[Fourth Option Exercise]

Next will be described odnorazovyy diaper fourth variant implementation. In the disposable diaper Z4 of the fourth variant of implementation, the layer of hinge element used as the site of engagement in the first embodiment, is formed by applying a layer of hinge elements for fastener type hook and loop, different light regulation of the efforts of the engagement.

The layer of hinge elements of a typical fastener type hook and loop is used, in addition to disposable diapers variant implementation, disposable products, such as absorbent articles, surgical coats, packing materials or the like, without limitation disposable diapers.

Configuration that is different from the characteristic sites of engagement are the same as the configuration of the first variant implementation. Accordingly, hereinafter will be described, mainly, the layer of hinge elements, which is used as a characteristic plot of the mesh and which differs from the first variant implementation.

In layer 2 looped element fastener type hook and loop in accordance with the embodiment, as shown in Fig. 6 and 7, the hinge element 20A, forming the surface layer of the base hinge 20, on which many hinge elements 20A, 20A ...from which fibers are formed into a loop or arch, perforated protective layer 21, having set the STV holes 21A, 21A ..., laminated and sealed with adhesive 22, and out of the holes 21A perforated protective layer 21 on the outside is exposed to the portion of the surface, where there are a lot of loop elements 20A, 20A.

In the layer of hinge elements when the location of the holes 21 located on the perforated protective layer, it is suitable designed for a regulation of the unprotected surface of the hinge elements, the force of engagement to part or all of chrysochroa element of the plot gearing is very easily controlled. That is, when the perforated protective layer has a uniform pattern of holes, easily adjustable, the total force of the engagement section of the engagement. On the other hand, when the perforated protective layer has a non-uniform pattern of holes, easily adjustable part of the efforts of the engagement section of the engagement.

For example, when multiple types of holes are different on the surface, are arranged in individual areas or the location of the densities of the individual zones differentiated, rapidly forms a site of engagement, distinguished partly in force engagement. By carrying out this, compared with the case where the hinge elements or the base of the loops melts or razravnivaetsya by stamping for partial regulation shall I force gear which mostly prevents hardening of the area of engagement.

In this document, the base hinge 20 is a layer containing a number of loop elements 20A, 20A, suitable for engagement with a corresponding Kruchonykh layer and existing examples you can apply themselves known different types of layers of looped elements. For example, you can enumerate woven material on one surface on which is formed a variety of hinge elements in the form of a loop or arch-shaped, or non-woven material obtained by processing of a cloth made of synthetic fibers such as olefin, including polyethylene, polypropylene and the like, polyester, polyamide and the like, recycled fibers, including rayon, copper ammonia fiber and the like, and natural fibers such as cotton and the like. They are obtained by an appropriate method such as a method of Hydrobotany, how sprzedania, the method of thermal bonding, spunbond-inflatable method, method of needle punching of holes, the method of shrinking or the like, for forming on one surface of the hinge elements in the form of a loop or in the form of an arc. From the point of view of less costly, more preferred is a non-woven material.

Among the ways in which PTS is seen formed hinge elements in the form of a loop or arch for non-woven material, how hydromotive gives excellent properties of flexibility and Dragonheart, and thermal bonding method is excellent in the receiving volume and softness, respectively, can be appropriately selected depending on the object. In this paper non-woven material may be a laminate of nonwoven material. For example, you can enumerate the laminate of nonwoven material obtained through appropriate laminating two or more layers of the layer of spun nonwoven material (S), where the fabric is formed by way of sprzedania, and a layer of inflatable nonwoven material (M), where the fabric is formed by spunbond-inflatable method that can be used as the starting material.

When constructing the base hinge 20, the extent to which the set force of separation between the base of the loops 20 and corresponding Kruchonykh element can be favorably respectively to choose depending on the application. Needless to say, that should not be in the interval where uncoated perforated protective layer 21, the force of engagement becomes insufficient. In addition, the force of separation, where the perforated protective layer 21, which is located on the outer layer is damaged during the peeling or fibers are extruded from the holes 20A, 20A, that one is camping very risky for the formation of the pile, is excessive in the application, where repeated engagement and disengagement. In addition, similar to the force of separation is also excessive, too much interval is covered by a perforated protective layer 21 to limit the efforts of the engagement, therefore, lost a significant advantage. For example, such a case is excessive, when covered 90% or more in terms of the ratio of the area.

In terms of specific numerical values because of the division it is desirable to design so that it ranged from 100 to 1500 Gauss, and preferably from 140 to 400 Gauss.

The method of measuring the strength of the division is carried out as shown below. First fabric tape having a width of 50 mm and a length of 100 mm, bend in half in the direction of the width for the formation of the bent twice a fabric tape having a width of 25 mm and a length of 100 mm, and one end of the fabric tape is firmly attached layer Kruchonykh elements. At the same time Krutoy element layer Kruchonykh elements establish so that it was located outside of the upper end of the fabric tape.

On the other hand to stainless flat plate attached to the base of the loops in accordance with the present invention by applying a bilateral adhesive tape forming the hinge element surface which is saved as the top surface. Chrome is also both ends fixed craftool tape.

Then after Krutoy element and forming a hinge element surface is brought into contact, the roller having a mass equal to 2 kg, once moving them back and forth from the side tissue tape to compress and attach krachodnok layer and the base layer of loops. In addition, at the other end side opposite to the side where the joins Krutoy layer fabric tape for 10 seconds suspend the weight of copper equal to 1 kg, for the application of shear force to the compressed and attached parts to ensure engagement.

After this stainless flat plate and the other end on the side opposite to where the attached layer Kruchonykh elements fabric tape is clamped by a clamping device breaking machine. At the same time, the direction of stretching clamping device that clamps the other end on the side opposite to where the attached layer Kruchonykh elements fabric tape set so that is 90° to the stainless steel flat plate.

Thus, after the clamping device is set to a tensile testing machine so that the final angle of exfoliation could be 90°, compressed and attached part prepare the chin with a speed of 300 mm/min, and bulk top and bottom of their values, measured in this case, is selected as the force of separation. The value of the measurements obtained by averaging the effective dimension values from 3 to 10 times. In addition, when the measurement sample is set to a dimension in the transverse direction (CD) in comparison with the transverse direction. Also, considering the size of the test specimen, Krutoy element mounted on 47 mm ± 3 mm (machine direction) × 93 mm (transverse direction) and the base hinge set 23.5±1.5 mm (machine direction) × 24 mm (transverse direction). In this document, the machine direction is the anteroposterior direction of the product, and the transverse direction is the direction of the width of the product.

When testing the effect of separation, you can apply a tensile machine (trade name: AOUTGRAPH AGS-G100N, manufactured by Shimadzu Corporation).

On the other hand, when constructed the base hinge 20, the degree to which set the shear layer between the base of the loops 20 and corresponding Kruchonykh element, respectively, is selected depending on the application. Is not desirable shearing force, which does not cause coupling, even when not used perforated protective layer 21. In addition, it is not desirable shearing force at which the load uses the I to the inner peripheral portion of the hole, possibly causing damage. On the contrary, is not desirable shearing force that is too strong in the sense of engagement, to give a sense of rigidity that leads to loss of benefits fastener type hook and loop.

In terms of specific numerical values of shearing force, it is desirable to design so that it ranged from 1 to 10 kg and preferably from 3 to 8 kg shearing Force is measured, as shown below. First to stainless flat plate attached to the base of the loops in accordance with the present invention by applying a bilateral adhesive tape forming the hinge element surface which is saved as the top surface. Then both ends fixed by applying craftool tape. At the same time on the periphery of the base layer loops leave the edge of the stainless steel flat plate.

Then after Krutoy element sasagawa tape is brought into contact with the forming hinge element surface therein, a roller having a mass equal to 2 kg, once moving them back and forth from the side tissue tape to compress and attach krachodnok layer and the base layer of loops.

After that, the edge portion of the stainless steel flat plate and one end sasagawa tape is clamped by a clamping device razryvnymi. At the same time, the distance between the clamps mounted on 50 mm After clamping is coming to an end, the clamping device is pulled in the direction of the shift krachodnok element and base layer loops with speed tension equal to 30 mm/min, to measure the maximum shearing forces. The value of the measurements obtained by averaging the effective dimension values from 3 to 10 times. In addition, when the measurement sample is set to a dimension in the transverse direction compared to the transverse direction. Also, considering the size of the test specimen, Krutoy element mounted on 47 mm ± 3 mm (machine direction) × 93 mm (transverse direction) and the base hinge set 23.5±1.5 mm (machine direction) × 24 mm (transverse direction). In this document, the machine direction is the anteroposterior direction of the product, and the transverse direction is the direction of the width of the product.

On the other hand, perforated protective layer 21 is applied to the coating forming the hinge elements of the surface layer of the base hinge 20 to regulate the efforts of the mesh base layer of loops 20, respectively, can be favorably applied layer of material, less force engagement with Kruchonykh element than with layer osnovaniya 20.

However, the perforated protective layer 21 is not limited to the layer that is not engaged Kruchonykh element. For example, you can also apply this layer, which has a hinge elements capable of engagement with Kruchonykh element. You can also apply the material layer, which has a force stronger engagement with Kruchonykh element than with the base of the loops. These applications extend variations of the design efforts partial engagement force separation Kruchonykh element section of the engagement.

The source materials of perforated protective layer 21 are not particularly limited and include various types of layer polymer film, such as a layer of plastic film and the like, a nonwoven layer, a woven layer, an elastic layer and other various types of known materials for the layer. When using perforated protective layer, which has the hinge elements can be favorable to choose the material for the layer that is different from the base layer of loops.

When the nonwoven layer is used as a perforated protective layer, the mass per unit surface area of the fibers is increased to increase the density of the fibers or by regulating the degree of processing due to the different types of processing methods, such as method of Hydrobotany or similar, get fiber is poverhnosti fewer or height of the loop portion to form a loop or part with the arch thus formed nonwoven layer that has a smaller force engagement with Kruchonykh element than with the base hinge 20.

As the perforated protective layer 21, preferably when the texture sensation is suitable nonwoven layer, and preferably when limiting the efforts of the engagement, a suitable layer is a polymer film, the best surface smoothness.

Many of the holes 21A, 21A, located on a perforated protective layer 21 are exposed to the holes 21A, 21A exposed to external influence hinge elements 20A, 20A of the base layer of the loops 20, and Krutoy element engages with the base hinge 20 through holes 21A, 21A.

Accordingly, taking into account the location of snagging on the diaper, size, number, location, and similar open areas of the holes 21A, 21A appropriately constructed so as to regulate the force of engagement to the appropriate value, or the force of engagement can be differentiated stepwise or continuously for each corresponding location.

When the open area of one of the holes 21A more than a substantial area of engagement krachodnok element, the restrictive effect of the efforts of the engagement is not m which can easily be achieved, accordingly, an open area of one hole design so that it was less than a substantial surface engagement krachodnok element sasagawa tape.

As the shape of the hole 21A is different from all the holes shown in Fig. 6, as shown in Fig. 8 and 9, it is possible to form a narrow, similar to the slot opening, which has a predetermined width and is located along the width direction or the longitudinal direction of the layer. The hole shape is not particularly limited and, although not shown in the illustrated example, it is possible to form a triangular hole, and it is not necessary that the holes were identical.

In the illustrated example to describe the configuration of the layer of hinge elements with descriptive purpose intervals are holes or openings in the form of slots having the same shape and size. However, in the case from the center in the width direction toward either side, the force of engagement varies stepwise or continuously to separate areas from the center in the width direction toward the outer part of the series, are round holes, characterized by open space, differentiated density arrangement of round holes having the same open space, and appropriate the way you designed a distance of the width of the slits or the distance between the slits.

On the other hand, the holes 21A, 21A from the point of view of their applicability in the area of engagement can favorably be adjusted so that they had a size in the range essentially from 30 to 80% of the total open area (total area, including the open area of all the holes) with respect to the entire area of the layer 2 looped elements. In this case, when each hole is round, essentially 200 holes, and each has a diameter equal to 5 φ, can favorably be placed at 80 cm2and when the slot has a width of from 1 to 5 mm, the slits can favorably be placed in increments of essentially 2 to 5 times greater than the width of the slot. To this extent it is possible to achieve sufficiently limit the efforts of the gearing and you can create your preferred effort.

In addition, the interval to the point where the force of the separation layer from the base of the hinge 20 is reduced by 10 to 50%, suitably constructed the way the holes. The invention without the necessary limits of this interval of numerical values can appropriately be changed depending on the application.

When the base of the loops 20 and perforated protective layer 21 are fastened, depending on the respective material layers can be applied with an adhesive selected from known adhesives. Is appropriate, this adhesive, which becomes solid after bonding. In the present invention it is undesirable to increase the rigidity caused by the melting of the hinge base, caused by heating, respectively, is not the preferred thermal melting. Despite this, even when thermal melting stiffness is not increased so much, when there is a spot embossing, where the area of one point is 5 mm2or less and the speed stamping is 10% or less, or is a linear embossing, where the line width is 1 mm or less and adjacent lines are separated by 3 mm or more, you can apply similar thermal melting. Bond thanks to the hot-melt adhesive is preferred for the bonding material layers, such as nonwoven fabric or the like. Hot-melt bonded part with hard-cure bonded part may be bonded material layers. In particular, based on hot-melt adhesives, it is preferable for the adhesive, where the concern is evident, therefore, that it was impossible to break the elasticity of the nonwoven material used in absorbent products and hygiene products.

In this document, when fastened both material 20, 21 layers, the adhesive may be applied to the side of slotsnobanes loops or it can be applied on the side of the perforated protective layer. If desired, the adhesive can favorably be applied to the appropriate side and laminate for bonding. It is easier to get through drawing on a perforated protective layer 21 than applying the adhesive onto the base of the loops, a different picture of the location of the holes.

When applying the adhesive, the adhesive can be applied to the entire surface of any one of the base layer of the loops 20 and a perforated protective layer 21 or apply on the portion of the surface lines or points. In addition, through the use of machines for applying coatings, such as a device for coating via slotted head or the like, the adhesive can be applied directly to the material layers. Alternatively, you can dissipate the hot-melt powder or you can use the spray nozzle to disperse the adhesive coating. The coating is not particularly limited.

On the contrary, the layer 2 looped elements of the present invention by imparting elasticity perforated protective layer 21 corresponding holes are formed with the extension due to this elasticity. As such elastic layer can be listed, for example, elastic non-woven material, which is engaged between the fibers and woven material that provides elasticity due elm is the Oia. When making holes, expandable thanks to elasticity to engage the holes with Kruchonykh elements of the holes are expanded to allow the engagement, and after engagement by reducing the number of holes you can reduce the impact on the loop, which is not necessary.

On the other hand, the layer 2 looped elements of the present invention elastic material with elasticity (not shown in the drawing), such as rubber thread, elastomeric layer, the urethane layer, the other elastic layer with elasticity or the like, is located between the base of the loops 20 and a perforated protective layer 21, which makes it possible to make the elastic layer 2 looped elements. Thus, when the elasticity is given by applying the elastic element in such a manner, the holes 21A, 21A are hiding between the folds caused by reduction of a layer 2 looped elements, and openings 21A and 21A notably seen when the layer 2 looped elements stretched. When the holes 21A and 21A appear to lock, long state of the layer 2 looped elements is broken to give the ability to hide the holes 21A and 21A, which are not necessary for engagement, again between the folds. Thus, it is possible to reduce not intended engaged.

Can be about the time to choose the bond between the elastic element with elasticity and the corresponding layers. Like the above bonding layer between the base of the loops and a perforated protective layer, preferably applied hot melt adhesive.

[Fifth Variant Implementation]

Although not shown in the drawing, in the fifth embodiment of the present invention the hinge element is located on a rear layer and a perforated protective layer is located so as to cover the hinge layer. In this embodiment, the area of engagement of the second variant of implementation for the regulation of the efforts of the engagement section of the engagement as a whole, or to achieve a partial differences of the efforts of the engagement section of the engagement, choose perforated protective layer described in the fourth embodiment.

Since the basic configuration of the diaper is similar to the configuration of the second variant implementation, and perforated protective layer is similar to the layer of the fourth version of the implementation, their descriptions are omitted.

A unique configuration options implementation can be illustrated as follows. As the back cover layer, in the interval that includes the hinge element, a perforated protective layer, the hinge element is formed not only at the area of engagement, but also in the range of greater than this. For example, all of the back layer or part, which does not require eternulo element, you can cover part of the perforated cover, where there are holes. Thus, it is possible to appropriately form the plot of engagement. The bond between the back layer and a perforated protective layer applied in accordance with the bond between the layer of the base of the loops and a perforated protective layer, which is described in the fifth embodiment. In accordance with the fifth embodiment can also perform a location of an elastic element with elasticity and the like.

[Sixth Variant Implementation]

Next will be described a sixth option implementation. On a plot of gearing to increase the efforts of the engagement or as a means for the formation of partial differences in the force-separation on site engagement, to form the set of holes is used the way open holes penetrating through the rear layer.

Fig. 11(A) shows an example in which in a predefined interval defined as the area of engagement of the rear layer, which forms the area of engagement of the second variant of implementation, is a lot of penetrating holes 30, 30 ....

As is evident from the drawing, when the plot gearing X1 is a lot of holes 30, 30 ..., crocosmia elements 40, 40 ... krachodnok element engage with holes in which Ucrania efforts gearing. In particular, even non-woven material or the like, which has a low weight per unit surface area and is less bulky, provides sufficient force engagement. The force of engagement with sasagawa tape can be adjusted by varying the ratio of formation of holes.

As the flat shape of the holes 30, 30 ... in this case you can apply similar slits linear hole elongated in the longitudinal direction of the diaper or in the direction of the width of the diaper, or the aperture a rounded shape, such as round, elliptical shape or form in the form of a comma. In addition, their location can be either regular or irregular and may be optional on-site engagement. When it is used as a means for partial education differences in the force of engagement on the site of engagement, referring to efforts by the engagement of the respective parts, appropriately constructed the hole shape and density of the location.

In addition, the cross-sectional shape of the hole can be a form where the edge of the hole can be flat to the surface of the diaper, or as shown in Fig. 11(B), shape, protruding vertically outward from the diaper. When the edges of the holes 30e, 30e ... get up even just a little bit towards the outer surface, cruco the element is easily bent to ensure the efforts of the engagement.

From the point of view of reliability of the corresponding engagement efforts with Kruchonykh element or maintain strength non-woven material, it is desirable to form openings in the proportion of holes equal to from 30 to 80%, relative to the surface proportion of the area of engagement. When the proportion of the holes is less than 30%, crocosmia elements that are embedded in the holes, decrease so that he could not get enough pressure engagement. On the other hand, when the proportion of holes exceeds 80%, the strength of the nonwoven fabric becomes weaker, leading to a higher risk of rupture.
