THE TECHNICAL FIELD

The present invention relates to the infinite structures and, in particular, technical fabrics used in the manufacture of non-woven products. More specifically, the present invention relates to the creation of the supporting elements such as tape conveyors or sleeves are used in the manufacture of which has the image or marked with non-woven products. In addition, the present invention can be used as a conveyor belt and/or sleeves in the production of non-woven products in processes such as dry air, the formation of a cloth, meltblown (melt blowing), spunbond (spunbonding) and hitrospleteniya (hydroentangling).

THE LEVEL OF TECHNOLOGY

The production methods of nonwoven products known for a long time. According to one method fiber Holt or canvas processed by streams of water, or water jets for plexus fibres with each other and enhance the physical properties, such as strength of the canvas. For decades, the known ways of processing of the fibers in the water streams, which are described in U.S. patent # 3,214,819, №3,508,308 and # 3,485,706.

In General, this method involves the interlocking of single fibers with each other under the action of high pressure water jets, which act on the fibre structure as needles and provide the opportunity to direct a part of fibers with a cloth formation in the thickness direction.

Currently, this method is widely developed and used not only in the production of what are known as "hitrospleteniya" or "Hydrobotany, with application in the textile industry, in particular for applications in the field of medicine and hospitals, treatment, filtration and packaging of tea bags, and the resulting products can be regular and homogeneous, as follows from the description of U.S. patent number 3,508,308, and optionally contain patterns that result repurpose fiber, which is important for aesthetic purposes, as can be seen from the description of U.S. patent number 3,485,706.

In connection with the products of the type "hitrospleteniya" or "Hydrobotany" it has long been known that the final properties of the product can be selected through the formation of mixtures of material, for example by combining fabrics, containing fibers of different types, such as natural, artificial or synthetic, or even canvases in which fiber pre-mixed (blade type "spanbond" and so on) with reinforcing elements that can be included in non-woven structure.

In patents France FR-A-2730246 and 2734285 corresponding to the U.S. patent # 5,718,022 and # 5,768,756 described solutions successfully process hydrophobic fibers or their blends with other hydrophilic fibers or even paintings, composed entirely of natural fibers, water jets.

In General terms, in accordance with the concept described in these documents, the processing involves the processing of fabric bases, generated from a single fibers of the same type or of different types, compression and hydration specified canvas basics and then weave the fibers with at least one rack allied jets of water under high pressure acting on a fabric basis.

To this end, the canvas basics moves forward on a moving infinite porous support and transferred to the surface of a perforated rotating cylindrical drum to inner space of which is attached a partial vacuum. Canvas basics of mechanical compressed between the porous support and a rotating drum that both move forward essentially the same rate. Directly downstream from the zone of compression on the cloth goes water curtain, which passes sequentially through the porous support, compressed fabric basis and supports the perforated drum, the source of vacuum removes the excess water.

Single fiber constantly shuffled when they are still on a rotating cylindrical drum, with concise and moistened cloth is exposed at least one rack jets of water under high pressure. Essentially, this is done through a series installed racks jets of water that act or on the same side or alternately on both sides of the fabric, the pressure inside the poles and speed jets of water usually gradually decrease from one stand to another.

It is important to note, as the patent FR 2734285, perforated shaft/dryer can contain distributed randomly pinholes. If necessary, after the initial weave fiber non-woven fabric may be subjected to a second treatment is applied to the reverse side.

In the process of production of non-woven products performed hitrospleteniya or hidrostatyba, you often need to give the end product is a picture or markup to create the desired patterns. Usually such drawing or layout created with the use of an auxiliary process, separate from the formation of non-woven cloth and twisting process that uses the calender for stamping/printing. Usually such calenders expensive and operate on the principle of compression certain sections of fiber cloth to create the desired picture or markup. However, there are several drawbacks when using separate processes for creating a drawing or layout on a non-woven product. For example, to purchase calenders can require a large initial investment, which may limit the size of a lot of products that can be economically justified by the manufacturer. Second, due to the additional stage of drawing or layout arise higher production costs. Third, the finished product will contain more material than is required to ensure the necessary thickness of the product after the compression phase calendering. Finally, a two-step process leads to a smaller volume weight of the finished product than we would like, because of the strong compression in the calendering process. Known from the prior art nonwoven products manufactured using these known processes of drawing, do not have clear, sharp relief parts and, therefore, the required drawings trudnorastvorimy. In addition, the sizes of relief parts known printed non-woven products unstable, and relief parts tend to lose their three-dimensional structure, when after some time, they are subjected to loads depending on the application.

In the U.S. patent # 5,098,764 and # 5,244,711 disclosed application supporting element in a more modern method of production of nonwoven materials or products. Supporting members have the configuration, which is characterized by the surface topography, and also contain an array of holes. In this process the source of fiber cloth is placed on supporting element with relief surface. Supporting element with on him fiber cloth is held under the jets of liquid, usually water, under pressure. A jet of water cause the fibers to twist and weaved with each other with a distinctive pattern, in accordance with the configuration of the surface relief support element.

The pattern of the particular topography and holes in a supportive element is important for the structure of the obtained non-woven products. In addition, supporting element must have sufficient structural integrity and strength to support fiber cloth, while a strong jet of liquid reorienting and mixed fibers in their new position with the formation of a strong fabric. Supporting element should not be exposed to any significant curvature under the action of liquid streams. In addition, supporting element must have a means for removal of relatively large amounts of fluid used to hitrospleteniya fibers, to avoid "flooding" fiber fabric, which will impede the effective hitrospleteniya fibers. Usually supporting element contains the drain holes which should be small enough to ensure the integrity of fiber cloth and prevent the loss of fibers through the forming surface. In addition, supporting element on the merits should not have burrs, hooks or similar irregularities, which can interfere with the withdrawal of fiber non-woven products, made by hitrospleteniya fibers. At the same time supporting element should be such that the processed on him fiber optic paintings will not be washed away by the action of liquid jets.

One of the main tasks, which occurs in the process of production of non-woven products, is to reach the clutch fibers in the production of nonwoven material with the purpose of giving non-woven products strength characteristics in accordance with the application, while maintaining or making the special physical characteristics, such as volumetric weight, tactile properties, appearance, etc.

Properties - volumetric weight, absorbing ability, strength, softness and aesthetic appearance is really important for many products, when used for its intended purpose. For manufacture of nonwoven materials with such characteristics supporting element will often be configured to contact with the road surface would have had changes of surface relief.

The present invention provides tape and sleeves, which are suitable for use as a traditional textile fabric and making the desired texture, tactile properties and volumetric weight made them non-woven products.

SUMMARY OF THE INVENTION

Therefore, the main objective of the invention is to create superior conveyor belt or sleeves, which give the desired texture tactile properties, volumetric weight, appearance, absorbing ability and strength made them non-woven products.

Another object of the invention is to create a support item made by hitrospleteniya, such as a belt or a sleeve, containing a through emptiness, located with the formation of the desired image. In addition, supporting element can be used as technological conveyor belt or hose in processes such as dry air, the formation of a cloth, meltblown (melt blowing), spunbond (spunbonding).

Another objective of the invention is to create a conveyor belt or sleeves that can be surface or texture on one or both sides due to the pattern through holes or cavities. The present invention achieved these and other objectives and advantages. Provided other benefits in comparison with known textile fabrics, such as, but not limited to, improved support and the release of fibers (no extraction) and more easy cleaning due to the lack of places to weave, capable of holding a single fibre. If a tape of the conveyor/sleeve have the texture of the surface, the pattern/texture more effectively transmitted non-woven product, and, in addition, it gives the best physical properties such as volume weight/ absorption capacity.

The present invention relates to the infinite supporting element such as a belt or hose for support and movement of natural, synthetic or artificial fibres in the process of hitrospleteniya or Hydrobotany. Porous structure, tape conveyors or sleeves according to the present invention have the following, not restricting, the benefits in comparison with the technology calendering; the sleeves are relatively less expensive and do not require large capital investments in stationary equipment; the drawing is performed simultaneously with the process of hitrospleteniya fibers eliminates the need for separate operations calendering; in the final product can be achieved with a lower content of the material, as the thickness does not decrease in compression; it is possible to produce the end product with high specific volume, because it is not compressed at the stage calendering as to the manufacturer of nonwoven roll materials, these benefits additionally lead to the following advantages of the final product: the lower cost of the materials made by hitrospleteniya fibers with the required drawings, markings or texture; possibility of manufacturing products according to special requirements of the customer, because of the reduced size of the party of particular products; the ability to produce high-performance products such as materials with high specific volume, which give greater absorption capacity, which is important for consumer goods.

Therefore, in accordance with one example of implementation of the invention of the proposed technical cloth, such as a belt or a sleeve, containing a through hole.

Then follows a detailed description of the invention with reference to the accompanying drawings showing the preferred options for the implementation of the invention. However, the present invention can be implemented in many different forms, and the invention must not be understood as limited options for implementation, illustrated in the present description. On the contrary, these illustrative options provided to make this discussion is finished and complete and pass the volume of the invention specialists in this field.

In the present invention offered continuous support element, such as a belt, intended for use, for example, in the device shown on figa. While in the description first described the process of Hydrobotany fibers in the jets of water and a cloth or tape, which is used in these processes, the field of application of the invention is not limited. With signs of the invention tape/sleeves are used also in other processes of production of non-woven materials, such as dry air, the formation of a cloth, meltblown (melt blowing), spunbond (spunbonding). Nonwoven supporting element suitable for use instead of the traditional textile supporting element and gives the desired texture, tactile properties and the volumetric weight made it non-woven products. Supporting element according to the present invention can reduce the time of manufacture and production costs associated with the production of nonwoven materials.

On figa shows a device for the continuous production of nonwoven materials with the use of the support item in accordance with the present invention. The device shown on figa, contains a tape 80 pipeline, which actually serves as a supporting element with a relief surface in accordance with the present invention. As is known, the conveyor belt moves in a counterclockwise direction around a pair of shafts, placed at a distance from each other. Above tape 80 pipeline throwing liquid collector 79 connects many lines or groups 81 holes. Each group contains one or more rows of holes of a very small diameter, each hole with a diameter of approximately 0,018 cm (0.007"), up to 30 such holes per inch (2.54 cm). Water comes to groups 81 holes pre-set pressure and thrown out of the holes in the form of very thin, essentially a columned, not deviating jets of water. Manifold equipped with gauges 88 and regulating valves 87 to adjust the pressure of the fluid in every line or a group of holes. Below each line or group of holes reception box 82 is designed to remove excess water and holding site of spam flooding. Fiber cloth 93, which must be formed in a non-woven material, comes to supporting relief item/ a belt according to the present invention. The water sprayed on the fiber cloth through the appropriate nozzle 84 to preliminary humidifying incoming sheet 93 and promote the regulation of fibers as they pass under the spray liquid collectors. Suction crack 85 located below the specified water spray nozzle to remove excess water. The fiber blade goes below the spray liquid collector counterclockwise. The pressure in each group 81 holes can be installed independently of the pressure in the other groups 81 holes. However, usually in a group 81 holes, most closely located to the spray nozzle 84, set relatively low pressure, for example 7,03 kg/cm 2 (100 psi). This facilitates the installation of the incoming sheet on the surface of the support element. Since the canvas moves counterclockwise, as shown in figa, pressure groups 81 holes usually increases. Not necessarily that each group 81 holes will operate at a higher pressure than the pressure in the next group of holes in a clockwise direction. For example, two or more neighbouring groups 81 holes can be under the same pressure, the following neighboring after the group 81 holes (in a counterclockwise direction) may be under a different pressure. Usually working pressure at the end of the conveyor belt, from which the cloth is removed, higher than the working pressure at the end of a canvas primarily supplied to the conveyor belt. Although on figa shows six groups 81 holes, the number is not important, but depends on the weight of the cloth, speed used pressure, quantity of rows of holes in each group, etc. After the passage between throwing header and suction manifolds, a newly formed non-woven material goes above additional intake slit 86 to remove excess water. The distance from the bottom surfaces groups 81 holes up to the top surface of the fiber cloth 83 is usually about 1.27-5.08 cm (0.5 to 2 inches), preferably 1,91-2.54 cm (0.75 to 1.0 inch). It is obvious that the painting could not be located as close to the collector, so that the canvas will be with him to touch. On the other hand, if the distance between the bottom surface of the openings and the top surface of the canvas will be too large streams of liquid loses energy, and the process will be less effective.

On figa and 1B shows a top view-through cavities 102, which were part of fabrics, ribbons or sleeves 104 in accordance with one example implementation. In accordance with one aspect through the voids are drainage holes that are used in the production of nonwoven materials in the process of Hydrobotany or hitrospleteniya fibers in water flow (hydroentangling). On figa depicted through emptiness 102 on the view from the top surface 106 (i.e. side of laser radiation)that is converted to laser source (not shown), thus, the laser source is made with the possibility of creating in tissue 104-through cavities or holes. Each end-to-end emptiness 102 may have a conical shape, with the inner surface of each 108 through emptiness 102 narrowed from inside the hole 110 on the upper side 106 through the hole 112 (pictured on FIGU) on the bottom 114 tissue 104 (pictured on FIGU). Bore diameter to 110 in the direction of coordinate axis X is designated as Δ x 1 , while the diameter of the hole 110 Y-axis is indicated as Δ y 1 . Similarly, referring to FIGU, hole diameter 112 on the X-axis is indicated as Δ x 2 , while the diameter of the hole 112 Y-axis is indicated as Δ 2 . Apparently from drawing, diameter Δ x 1 hole 110 X on the upper side 106 tissue 104 greater than the diameter Δ x 2 holes 112 X on the bottom 114 tissue 104. In addition, the diameter Δ y 1 hole 110 Y-axis on the upper side 106 tissue 104 greater than the diameter Δ have 2 holes 112 Y-axis on the bottom 114 tissue 104.

On figa shows a cross-section of one of the cross-cutting void 102 depicted on figa and 1B. As previously described, each through the emptiness 102 may have a conical shape, with the inner surface of each 108 through emptiness 102 narrowed from inside the hole 110 on the upper side 106 through the hole 112 on the bottom 114 tissue 104. The conical shape of each end-to-end emptiness 102 can be created as a result of the incident optical radiation 202 generated from the optical source, such as a carbon dioxide laser or other laser device. By applying laser radiation 202 with the relevant characteristics (for example, output power, focal distance, pulse duration, and so on), for example, non-woven cloth can be created through the emptiness 102 as a result of the laser perforation surfaces 106, 114 tissue 104. Creation of cross voids using laser devices will be described in the following paragraphs with the illustration of the experimental data.

As shown in figa, in accordance with one aspect of laser radiation 202 creates under the influence of first raised edge or ledge 204 on the upper side 106 tissue, and the second the raised edge or ledge 206 on the bottom 114 tissue 104. The raised edge 204, 206 can also be called a raised rim, or edge. Type in the plan down on the raised edge 204 with the upper point indicated by the number A. Similarly, type in the plan down on the raised edge 206 with the bottom point is marked by the number A. Both types A and A dotted line 205A and W are a graphical representation raised bezel or region. Therefore, the dotted line 205A and V not intended to indicate grooves. The height of each raised edges 204, 206 may be 5-10 microns. The height is calculated as the difference of levels between the surface of the fabric, and the top of a raised edge. For example, the height of the raised edge 204 is calculated as the difference in level between the party 106 and top 208 raised edges 204. The raised edge, such as 204 and 206, provide, among other benefits, local mechanical reinforcement for each pass-through cavities or holes which, in turn, contributes to the total resistance of this perforated fabric (for example, kiperousa tissue). In addition, the establishment of a deeper hollows facilitates the creation of deeper pockets made in non-woven products and, in addition, provided, for example, more volumetric weight and low density. It should also be noted that in all cases, the attitude Δx1 / Δx2 can be equal to 1.1 and more, and Δy1 / Δy2 can be equal to 1.1 and more. Alternatively, in some or all cases, the attitude Δx1 / Δx2 can be equal to 1 and the ratio Δy1 / Δy2 can be equal to 1, in consequence of which is formed through the emptiness of the cylindrical form.

While creating the tissue through voids with raised edges, can be performed with use of laser devices, obviously, can be used by other devices suitable for such effects. You can use a mechanical breakdown or embossed, and then the tapping. For example, on the surface of nonwoven material required pattern of ridges and the corresponding recesses can be done by stamping. Then, for example, every ledge can be done with mechanical breakdown or drilled with a laser.

On figa shows a sample implementation of a 300 system to create the tissue 302-through cavities 304. The system can contain 300 laser unit 306, block 308 laser control, head 310 laser and mechanical clamps 316, which is the fabric 302.

Using head 310 laser serves falling optical radiation 312 to tissue 302 through the tip 314 with the creation of cross void 304. Falling optical radiation 312 may be exposed to various components with the formation of the shape of the beam until the tip 314. For example, can have unique optical lens to produce a given operating distance (i.e. D w ) between the tip 314 head 310 laser and upper side of fabrics, ribbons or sleeve 302. Also can be used optical splitters, insulators, polarizers and/or other components to modify various characteristics of the incident optical radiation 312, coming from the head 310 laser. For example, one of the required characteristics can be customize the size and shape of the spots. As a result, the incident optical radiation drills (cuts) through hole or through emptiness in tissue 302.

Fabric, tape, or sleeve 302 can be set or are located on the appropriate device (for example, see FIGU)which consists of different components with a mechanical supply, guides, shafts and so on, made with the possibility to navigate tissue 302 and/or head 310 laser in the direction of X or Y. By controlling the movement of fabric 302 in the direction of X axis or Y on the fabric can be formed relief-through cavities in accordance with different required drawings. In addition to move on the X-axis or Y-working distance D w can be changed by setting the heads 310 laser on the platform with mechanical feed, providing axis coordinate Z. Perhaps you can develop a system in which the laser head moves in three directions, while the fabric remains stationary. Alternatively, the laser head moves across the tissue in the direction of the width of the "X" or in the direction of the CD (lateral direction), while the fabric moves in the machine direction (MD) or in the direction of the y axis. In addition, you can develop a system in which the fabric will move in three directions relative to mechanically fixed laser heads.

On FIGU shows a sample implementation of a device 320, which is used to create end-to-end voids cloth, tape and sleeve, according to one aspect of the invention. Depicted on FIGU fabric 322 should be understood as a relatively short part from the full length of fabric 322. In situations where the fabric 322 infinite, it is most expedient to set it around a pair of shafts, on this drawing is not shown, but well-known experts in this field. In this case the device 320 will be located on one of two sides of the fabric 322, preferably, on the upper side between the two shafts. However, whether the fabric 322 infinite or not, it is preferable that during the process it was located with an appropriate degree of tension. Moreover, to prevent sagging tissue 322 can be supported from below by means of horizontal supporting element as it moves through the device 320.

Turning more closely to FIGU on which the fabric 322 shown moving up through the device 320, as implemented method according to the present invention, a device 320 contains a sequence of several sites through which fabric 322 goes with a certain step in the process of its manufacture.

Fabric, tape, or sleeve, which are described in the above implementation, are one example of tissue that needs to be drilled in accordance with the systems and methods described in this description. Required characteristics created through hollows, which are described in this description, improve at least one of the characteristics of non-woven products, made on the fabric. Fabrics, designed in accordance with the present invention, improve the performance of machines for production of nonwoven materials due to the fact that pass-through cavities in tissue preferably conical shape with large holes on the side in contact with the paper, and the small holes on the side in contact with the components of the machine, which, in turn, allows the tissue to work with large levels pulling or smaller primary weight.

Figure 5 shows a scheme 500 sequence of the creation process into tissues through holes in accordance with one example implementation. At the stage 502 determine whether laser device to work in a forward-or multi-pass mode. In a forward-laser creates through the emptiness in one pass, during which he moved over cloth. In multi-pass mode, the laser passes over the cloth at least twice and applies the effect of optical radiation on the same places on the fabric until, until you have completed the creation of the required end-to-end voids.

If at the stage 504 determines that the selected one pass mode, installs a set of parameters of the laser (at the stage 506). The parameters of the laser can contain different settings that apply to the unit for laser control, such as a block 308 (see FIGU). At the stage 508 on the basis of set parameters of the laser output optical laser light punches arise from the fabric with the creation of cross void required form. At the stage 510, after analyzing the shapes/geometry created through the void (for example, visual inspection, receiving/processing images etc), determine whether through emptiness required criteria of the form (at the stage 512). If through the emptiness meet the required criteria of the form (at the stage 512), maintain the set parameters of the laser (at the stage 514)so that they can be reused in the process of drilling of the same or similar fabrics. On the other hand, if you determine that through the void does not meet the required criteria of the form (at the stage 512), reconfigure the parameters of laser that is used to drive the laser (at the stage 516), in attempt to create end-to-end emptiness with the required criteria of the form. Stages 512, 516, 508, and 510 process continues to run until, until you have met the required criteria form through cavities. Once the form has been created through holes will meet the required criteria form the fabric can be drilled completely.

If at the stage 504 determines that the selected multi-pass mode, installs a set of parameters of the laser (at the stage 520). The parameters of the laser can contain different settings that apply to the unit for laser control, such as a block 308 (see FIGU). At the stage 522 based on a set of parameters of the laser output optical laser light punches arise from the fabric with the creation of cross void required form. At the stage 524 after analyzing the shapes/geometry created through cavities or holes (for example, visual inspection, receiving/processing images etc), determine did perforation tissue through the void and does established through emptiness required criteria of the form (at the stage 526). If through the emptiness created and it meets the required criteria of the form (at the stage 526), maintain the set parameters of the laser (at the stage 528), so they can be reused in the process of drilling of the same or similar fabrics. On the other hand, if it is determined that, or through the emptiness was not created (for example, perforation surface tissue) or obtained through the void does not meet the required criteria of the form (at the stage 526), the laser passes on through the void in extra time, and puts optical radiation to the through hole (on the stage 530). Continue the process 526, 530, 532 (advanced stage) and 524 until, until you create through the emptiness, and through the emptiness will not meet the required criteria of the form. Once the form is received through the void would satisfy the required criteria form the fabric can be drilled completely. In addition, an additional stage 532 parameters of laser that is used to drive the laser, can be reconfigured to create end-to-end emptiness and/or set to the required criteria form through the void. However, it should be noted that the number of passes to create end-to-end emptiness varies according to many factors such as fabric material, the thickness of the fabric, the type of laser devices, characteristics of the laser control or characteristics of the unit for control of the laser, etc. but do not stop there.

Figure 6 presents the images of tissue that is drilled according to at least one aspect of the present invention. The image 602 illustrates drilled into tissues through emptiness, as can be seen from the upper surface of the fabric (i.e. by laser radiation). The image 604 illustrates drilled into tissues through the void, as they can be seen from the lower surface of the fabric (i.e. the opposite side). Criteria drilling was getting through voids circular containing the top open area on the side of the laser radiation, or the upper surface. The images 604 602 and shows the top holes (6) on the side of the laser radiation or top side in comparison with the holes on the bottom surface (Fig.6). Through holes can be drilled with the use of a carbon dioxide laser, which can be programmed or work for generation of optical pulses pre-set duration for a pre-determined period of time. Various other options associated with the drilling of through cavities may include, for example, setting power (in Fatah)generated by the laser vyhodnogo radiation, speed drilling, step-axis X and Y, working distance (i.e. the distance from the tip of the laser head to the surface of the fabric), density (number of holes per area), the requirements for the particular tissue and the number of passes for the action of optical radiation on tissue, but are not limited.

7 illustrated image tissue that is drilled according to at least one aspect of the present invention. The image 702 illustrates drilled into tissues through emptiness, as can be seen from the upper surface of the fabric (i.e. from the side in contact with the laser radiation). The image 704 illustrates drilled into tissues through the void, as they can be seen from the lower surface of the fabric (i.e. the opposite side). Criteria drilling was getting through voids with the top open area on the side in contact with the laser radiation, or on the upper side of the fabric in comparison with the holes on the opposite side or bottom side of the fabric. The images 702 and 704 shows the top of the hole (7) on the side in contact with the laser radiation, or the upper side in comparison with the holes on the bottom side (Fig.7). These cross-cutting void can also be drilled with the use of a carbon dioxide laser, which can be programmed or controlled for the generation of optical pulses pre-set duration for a pre-determined period of time. Various other options associated with the drilling of through cavities may include, for example, setting power (in Fatah) generated by the laser output radiation, speed drilling, step-axis X and Y, working distance (i.e. the distance from the tip of the laser head to the surface of the fabric), density (number of holes per unit area), the requirements for the particular tissue and the number of passes for the action of optical radiation on tissue, but are not limited. As shown in Fig.7, form holes in essence is oval in comparison with through voids depicted in Fig.6. Different factors and/or parameters (for example, drilling speed) can lead to differences in the shape and size (%) open areas through the void, the relevant party, laser radiation and the opposite side of the fabric.

On figa-8G illustrated images layered fabric drilled in accordance with one aspect of the present invention. Layered fabric according to this variant of the invention may contain at least two layers, connected with the use of appropriate way lamination. For example, carbon dioxide laser can operate in a pulse mode, providing power output, for example, approximately 600 Toscalido drilled fabric laminated, through the void created after multiple passes of the incident optical radiation.

On figa-8G illustrated made under the microscope image showing the depth of penetration of the incident optical radiation with each pass, from the first to the seventh. In addition, these images show the raised edges, formed during drilling. Examples of such high edges (i.e. the top surface) is marked by the number 804 (fega), 806 (FIGU), 808 (fig.8G). With each pass, figa-8G illustrated some increase holes on both surfaces through emptiness, top and bottom. For example, the image on fig.8D shows the hole on the upper surface, which has a diameter of approximately 3.2 mm on the upper surface and a diameter of approximately 1.4 mm on the lower surface through the void after the fourth passage. However, after the seventh pass, as illustrated in fig.8G, hole on the upper surface has increased up to a diameter of approximately 3.3 mm on the upper surface diameter and about 2.5 mm on the lower surface through the void. These results show that building an end-to-end emptiness had to do 5 passages. However, it should be noted that the number of passes to create end-to-end emptiness varies according to many factors such as type of layered material, thickness of the layered material, the type of laser devices, characteristics of the laser control or characteristics of the unit for control of the laser, etc. but do not stop there.

Figure 9 illustrated with pictures of both surfaces drilled through the emptiness of upper 902 and lower 904, relevant fig.8G (i.e. after the seventh pass). As shown in figure 9, after the seventh pass the shape of the holes on the top and bottom surfaces through emptiness becomes essentially rectangular.

Figure 10 shows some drawings through voids obtained experimentally with the creation of cross voids in accordance with another aspect of the present invention. In some instances may be required through the voids larger. For example, the limiting factor may be the size of the laser spot. In order to overcome this limitation and create end-to-end voids larger size, it is advisable to use a laser device as a cutter, and not as a drill. To create end-to-end voids larger to ensure this milling head is laser can swing from side to side with a different frequency (frequency sweep) and strength criteria (for example, the exponent, swing).

In another variant of realization of the structure of tissue that may contain or not contain the base support base, contains contact with the road surface with a sequence of jumpers and recesses, and branched structure of voids, made with the possibility of giving texture paper napkins, paper towels or nonwovens. On FIGU shows a cross-section of the surface structure 10 tissue branched void or hole 11 containing small holes 10A and 10b-side 12 in contact with the canvas that are tilted, so that they blend into the void 10th larger on the opposite side 14 tissue. As shown, an extensive hole 11 can also be formed with the inclusion of the ring raised edges or headbands 16 adjacent to the circles of holes 10A and 10b. Although on FIGU not shown, raised edges or headbands can also be built adjacent to the circle of emptiness 10th larger on the opposite side 14 tissue. Although holes 10A and 10b depicted as merging into the void 10th, may provide a branched structure of emptiness, containing at least three holes merging into the void larger, whereby can be formed raised headbands or related only with the smaller holes on the side in contact with the canvas, or also with emptiness larger on the opposite side. In addition, elevated headbands can cover fabric partially or completely.

This structure provides the creation of tissue structure of a large number of small holes, also, at the same time provides a small extension in the machine direction (MD) in the long time and high bending stiffness in the direction across machine (CD). In addition, this structure can be adapted so that, for example, it provides the holes in the fabric structure, which has a diameter less than the thickness of the base, creating, for example, sealed openings due to pollution.

Fabric structure containing the surface is described with a ramified structure, intended for applications of nonwoven materials. For example, coarse structure on the side in contact with the canvas, and the holes are smaller on the opposite side of contact with parts of the machine can provide, for example, capture, shape, and/or to Orient located in the structure of the fabric fibers in the desired picture and to ensure the production of textured nonwoven materials. As previously described, described emptiness can be direct (cylindrical or conical. For example, can be designed conical holes of different images, so they are larger and well distributed on one side, for example, in contact with the canvas, while void on the opposite side of contact with the machine components can be essentially aligned in the machine direction, by providing, for example, increased drainage. Extensive emptiness can be created with any number of ways perforation or combination thereof, including drilling laser, mechanical punching and stamping (thermal or ultrasound). For example, voids can be created by a combination of laser drilling and stamping.

It should be noted that the previously mentioned non-woven technical tape't give a structure made them non-woven product. The term "structure" refers to the changes of the main weight and/or density non-woven cloth, which is more than they deliver in the ordinary course of production of nonwoven materials due to regular change. However, the term "structure" can also refer to a texture or pattern of non-woven material. Such "structured" - woven materials are usually soft and loose with large absorbent. These tapes contain structural frame surface and can have a reinforcing structure. Structured nonwoven materials can be softer, more absorbent and have less basic weight than unstructured.

Technical fabric essentially contains two sides: the side in contact with the canvas, and the side in contact with the components of the machine. Side is in contact with the canvas, as it is a party tissue that is addressed to just molded non-woven cloth. Side is in contact with components of the machine, as it is a party tissue that goes over the shaft of the machine and come into contact with them.

On Fig shows a typical method, which can be made the tape 1110. The device 1220 contains the first technological shaft 1222 and the second technological shaft 1224, each of which can rotate around its longitudinal axis. The first technological shaft 1222 and the second technological shaft 1224 parallel to each other and are located at a distance from each other, which creates the full length of the tape 1110 made on this device, measured in the longitudinal direction. On the side of the first technological shaft 1222 is feeding Bobina (not shown), installed with the possibility of rotation around an axis and move in parallel with the technological shafts 1222 and 1224. Shafts 1222 and 1224 can be set so that the length of the wound upon them a cloth of approximately corresponds to the length of the resulting tissue. Feed Bobina supply from the reel strips 1116 material, which is wide, at least for example, 10 mm or more. Feed Bobina initially located at the left end, for example, the first technological shaft 1222 before going at full speed continuously to move to the right or to the other party.

In order to start the production of tape 1110, the beginning of the strip 1116 material takes place in tightly stretched from the first technological shaft 1222 forward to the second technological shaft 1224, around the second technological shaft 1224 and back to the first technological shaft 1222 the formation of the first round of closed spiral 1226. To close the first round of closed spiral 1226, the beginning of the strip 1116 material connected with the end of the first round of closed spiral 1226 at the point 1228. As will be discussed below, adjacent laps twisted in a spiral band 1116 material with each other connected by mechanical, thermal and/or bonding methods.

Consequently, subsequent rounds closed spiral 1226 formed by the rotation of the first technological shaft 1222 and second technological shaft 1224 in one direction of the arrows shown on Fig, at the time of filing strip 1116 material on the first technological shaft 1222. At the same time the band 1116 material that is wrapped around the first technological shaft, continuously connected to a band that is already on the ground technological shaft 1222 and the second technological shaft 1224, for example, mechanical and/or bonding or any other appropriate means with the formation of additional turns closed spiral 1226.

This process continues until, until you get a closed spiral 1226 desired width, measured along the axis of the first technological shaft 1222 or second technological shaft 1224. At this point the band 1116 material not yet wrapped around the first technological shaft 1222 and the second technological shaft 1224, cut and formed from her closed spiral 1226 preferably cut with the formation of the ends of fabric in parallel to each other and getting the desired width, and then remove from the first technological shaft 1222 and second technological shaft 1224 with the formation tape 1110 according to the present invention.

One way stapling or hold together adjacent strips of material in accordance with one variant of realization of the present invention is ultrasonic welding of adjacent bands edge to edge with the simultaneous pressing of side to hold the edges in contact with each other. For example, one part of the welding device can support one lane, preferably one that has already wound spiral, pressing her down into supporting the shaft, while the other part of the device presses to the top of another non-twisted strip it presses down the strip.

The intermittent use of ultrasonic welding leads to the creation of highly durable connection. In contrast, ultrasonic welding mode or full-time, or energy, also known as traditional ultrasonic welding, forming a fragile connection. Therefore, we can conclude that the connection is formed with intermittent use of ultrasonic welding, preferable in comparison with traditional ultrasonic welding.

Another way of holding together adjacent strips of material in accordance with one variant of the invention is the application of the glue the ends of adjacent bands and their connection. It should be noted that the filler can be used to fill in gaps or parts in which the lines are not in contact with each other.

Current methods and systems for the manufacture of tape 1110 are quite versatile and adaptable for the manufacture of technical fabrics or tapes with different longitudinal and transverse dimensions. I.e. the manufacturer during the implementation of the present invention is no longer necessary to produce an infinite or a smooth textile fabric and sew it to obtain appropriate length and width when installing on a machine for the production of non-woven fabrics. On the contrary, the manufacturer only needs to have the first technological shaft 1222 and the second technological shaft 1224 from each other at an appropriate distance, which forms the approximate length of the tape 1110, and wind band 1116 material on the first technological shaft 1222 and the second technological shaft 1224 until then, until a closed spiral 1226 required width.

In addition, due to the fact that the tape 1110 made spiral wound stripes 1116 material and is not the textile cloth outer surface 1112 tape 1110 is smooth and steady, and there are no places to weave, which prevent the surfaces of the textile fabrics to be absolutely smooth. Preferably, the strip of material can be stripe thermoplastic material, such as film or foil, and can be made of any polymeric material, preferably polyester (PET). However, you can use other materials, such as other polyesters (for example, polyethylene Naftalan (PEN) or polyphenol sulfide (PPS)). You can also use polyamides or polyetheretherketone (PEEK). As for the layered material that contains at least two layers, each layer can be formed from the same material or different materials. Material film or foil can be uniaxial or biaxial oriented with sufficient module and stability in both directions, native and cross, for the intended way. In addition, the film or foil can contain reinforcing fibres in machine direction or transverse direction or in both directions, machinery and transverse, or in any random direction. Reinforcing fibres can be enabled through the process of extrusion or pultrusion with which the fibers can be extruded or obtained by pultrusion together with the material, forming a film or foil. Reinforcing fibres can be generated from high-modulus of the material, such as, for example, aramids, including Kevlar and Nomex®, but are not limited and can provide the film or foil additional strength, modulus, tear resistance and/or spreading of cracks.

Alternatively, the strip of material can be a band of nonwoven material generated from low-melting fibers, such as polyamides, which can be kardovani and United igloprobivnye or other appropriate means and that can be fused transmission strip of material, for example, through the heated zone of contact with the formation of a smooth surface on one or both sides of the strip of material. In addition, non-woven material may contain a mixture of different materials, such as, for example, a combination of low-melting and high-melting fibers, such as 90% low melting of polyamide 6 in combination with 10% polyamide 6,6, or any other combination, matched to give the required characteristics. Alternatively part of nonwoven material may contain two fiber, such as, for example, fibers, containing the core and shell, which can include low-melting material outside and functional material inside. In addition, the strip of material can be covered with polyurethane resin to make the surface of the fabric additional smoothness. The coating can improve the removal of the cloth, and/or the structural integrity of the band's material. The above structure can then be perforated in the above way.

On figa illustrated image of the upper side of fabrics, ribbons or sleeves 1302 containing through cavities drilled essentially a diagonal pattern, in accordance with the alternative implementation of the present invention. For example, through emptiness 1304 drilled in accordance with diagonal 1306 in relation to the transverse direction (L) fabrics, tapes or sleeves. Similarly, on FIGU illustrated by the image of the bottom side of the fabric 1302 containing through cavities drilled on the merits in a diagonal pattern. As illustrated, through emptiness 1304 drilled in accordance with diagonal 1306. Illustrated image tissue 2302 contain svetlanoy cloth length 15 m, in which the size of the holes on the top side is, for example, about 1.5 mm (in the transverse direction)x 1.2 mm (machine direction), and the size of the holes on the bottom side of approximately 0.65 mm x 0.5 mm for Example, the distance between the holes in the transverse direction is approximately 1,695 mm, and the distance between the holes in the machine direction is approximately 1,18 mm

Similarly, on figa-14C illustrated image of fabrics, tapes, or sleeve, containing a through cavities drilled different patterns in the different aspects of the present invention. For example, fabric 1402 contains through cavities drilled in the picture that looks like a square scheme 1403. Larger image of the site a within the tissues 1402 number 1404b. To increased image section 1404b added dotted areas 1405 for improved visual perception of the figure-drilled holes. Similarly, another larger image area a within the tissues 1402 number 1406b. To increased image area 1406b added dotted areas 1407 for improved visual perception of the figure-drilled holes.

In accordance with another example of fabric 1410 contains through cavities drilled so that improved appearance square schemes 1411. Larger image of the site a within the tissues 1410 number 1412b. To increased image area 1412b added dotted construction lines 1413 for improved visual perception of the figure-drilled holes. Similarly, another larger image area a within the tissues 1402 number 1414b. To increased image area 1414b added dotted construction lines 1415 for improved visual perception of the figure-drilled holes.

In accordance with another example, fabric 1418 contains through cavities drilled in accordance with another figure 1419. Larger image of the site a within the tissues 1418 number 1420b. To increased image area 1420b added dotted chalk line 1422 for improved visual perception of the figure-drilled holes. In short, through cavities or holes, formed in fabrics, tapes or sleeves according to the present invention can be separated flat jumpers that can be of any geometric shape of the desired size. Despite the fact that the drawings depicted geometric shapes, such as a diamond, and square, these forms are represented only as examples, and end-to-end figure cavities or holes can be modified with the formation of almost any shape jumpers, such as, for example, diamond-shaped, triangular, square, rectangular, round, hexagonal or polygonal shapes, as well as an image of plants, in the form of a parallelogram.

As noted earlier, having features of the invention fabric may be used as tape or sleeves, which are used in processes such as dry air, the formation of a cloth, meltblown (melt blowing), spunbond (spunbonding) or hitrospleteniya in water flow (hydroentangling). Fabric according to the present invention may contain one or more additional layers on the top or bottom of the base, formed with the use of the bands material, only to ensure the functionality and not for gain. For example, used additional layers can be formed from any woven or non-woven materials, systems of threads, oriented in the machine direction (MD) or in the transverse direction (CD), twisted in a spiral bands of woven material, the width of which is less than the width of fabric, fiber paintings, films or combination thereof, and may be attached to the base using any suitable known way. Thermal lamination connection and chemical compound are only some examples.
