The invention relates to new carpet structures with enhanced dimensional stability and integrity, and more particularly to such type of carpets, their coatings, which are placed with the use of hooks and loops, as described, for example, in U.S. patent 4822658, class B 32 B 3/00, 1989.

Most carpets are experiencing some stability problems of their sizes when changing temperature and humidity conditions and, in some cases, due to insufficient strength in heavy traffic circulation and trucks, etc., These problems are particularly acute when using nylon as the main NAP layer, so as nylon absorbs moisture and carpeted floor rnym type of material for use in the manufacture of carpets due to its durability and cost.

Typically the nylon used for the manufacture of the pile of the carpet and its wcreplays to the main substrate of polypropylene, with which it fasten mostly latex binder applied to the reverse side of the base.

Nylon pile, which is embedded in the original basis, in itself elastic and relatively stable and resistant to the formation of folds and wrinkles as a result of changes in atmospheric humidity or temperature, however, this semi-finished product has no stability, weight or strength of the pile to be carpeted. It's just a piece of textile material. Typically, the integrity give this initial basis by attaching a latex binder for bonding together the tufts of the pile, remaining under the original framework to add weight, stability and durability of the substrate. However, once this is done, problems can occur due to the growth of the fibers in the main pile as a result of changes in relative humidity or temperature in the atmosphere cause excessive tension in your carpet as a whole. The result may appear folds, wrinkles and stratification, and in areas of high traffic of human sweat the size and the destruction of some types of carpets, especially carpet carpets and rugs width of about 6 feet (1.83 m) in width or less, which consists in increasing their heavier and more rigid fastening nylon pile tufts in the backing using more and more of adhesive, glue or binder. Other attempts have been made to enhance dimensional stability carpets by introducing the basis of optical fibers. Although these attempts can provide greater stability, they do not fully satisfy the requirements of the stability and integrity in a changing atmospheric conditions imposed on the absolute majority of the carpet, especially carpet large width exceeding 6 ft (1.83 m). Most of these carpets require bonding to the floor almost all their wrong side, usually by gluing support the stability and integrity in a changing atmospheric conditions. This method complicates the laying of carpets "free-floating" system, i.e. a system in which the carpet is fixed when laying only on the perimeter and along the seams.

One of the approximations to the solution of this problem is moisture carpet during A the Penzion 2 January 1996 Hydration to produce a deliberate evocation of the expansion of the carpet and then the carpet is fixed in place using a system of hooks and loops. This approach, however, does not answer the question of how to get the carpet, which didn't begin to swell, when the pile of nylon fiber becomes wet.

The closest analogue of the claimed group of inventions is a carpeted floor, the base of the carpet and method for the production of carpets for U.S. patent N 4822658. In this patent presents the basis of carpet for use in a carpet laid on the floor with additional hooks, siteplease the loops available on the wrong side of such a framework, with loops sewn into and through the first layer so as to essentially cover the first side of the layer exposed loops, the first layer is a first bottom layer of fibrous nonwoven material, and the second side of the lower layer has a binder for fixing the loops in the lower layer.

Known carpeted floor (see the aforementioned patent), with exceptional dimensional stability, containing the first part of the carpet, consisting of a main SL is om, that left the pile tufts on the second side of the base layer and the binder covering the pile tufts, and the second part in the form of the basics about the first part.

Also known is another basis of carpet containing bottom layer of nonwoven fibrous material having two opposite first back and the second hand, and intended for use in a carpet laid on the floor with additional hooks, siteplease the loops available on the wrong side of such a framework, and loops, stitched and substantially cover the first side of the lower layer and on the second side of the lower layer binder for fastening loops in the lower layer.

Another famous carpeted floor has a main layer with pile, essentially covering the first side of the layer, while the pile is stitched through the core layer so that the left pile tufts on the second side of the base layer and the first binder, coating the pile tufts to bond the pile with a layer for laying on the floor with additional hooks, siteplease the loops available on the reverse side of the base, and the first side of the layer of the framework is attached to the second is upomyanuty patent).

Also known is a method of manufacturing a multilayer carpeting with top component of the pile and the bottom layer framework including manufacturer located above the pile of the component layer with a cloth, stitched and pinned layer by wrapping the connecting beams and pile fastening to additional hooks on their second side to the reverse side of the upper component.

The disadvantage of the coating, and the method is not achievable desired stability and strength in direct relation to the value.

It is desirable to have a number of designs that can be used to create a carpet with a given stability in accordance with predefined criteria, to meet the requirements meets the intended use of them assumed rates. Useful if such designs can be selected when you want to achieve given the selected parameters, dimensional stability and the desired level of integrity.

The technical result of the present invention is that it provides a framework carpet and base with excellent stable is velichenie mass of the binder and its density on the wrong side of the base layer basics, which would seem rather complicated, easier than solving the problem of providing dimensional stability carpet under varying atmospheric conditions, as well as the fact that elastic stable in size light auxiliary layers may be attached if necessary as a basis for giving the required stability of the core layer.

According to one aspect of the present invention, this result is achieved by the fact that created the basis of carpet for use in a carpet laid on the floor with additional hooks, siteplease the loops available on the wrong side of such a framework, with loops sewn into and through the first layer so as to essentially cover the first side of the layer exposed loops, in which the first layer is a first bottom layer of fibrous nonwoven material, and the second side of the lower layer has a binder for fixing the loops in the lower layer, on the second side of the lower layer coating to reduce the penetration of the binder in the lower layer, which is thermally bonded to stabilize the fibrous layer of nonwoven material or the bottom layer bonded point bond.

The first layer of the framework is a layer of nonwoven fibrous material from thermally bonded polyester fibers and loops sewn into the first layer technology Malimo". The amount and viscosity of the binder at the second side of the first bottom layer of fibrous nonwoven material basis consistent with the density of the lower layer so that such binder penetrates into both sides of the lower layer to fasten the hinges in the lower layer, but without the pollution of the loops on the first side.

According to another aspect of the present invention, also ensuring the achievement of a specific result, created carpeted floor, with exceptional dimensional stability, containing the first part of the carpet, consisting of a main layer with pile, essentially covering the first side of the layer, and the pile is stitched through the core layer so that the left pile tufts on the second side of the base layer and a binder, ohvatyvayuschie in and around the pile of beams, in order to allow the pile tufts to expand and shrink, while the second part is formed from one or more layers so as to have a predetermined resistance to expansion and shrinkage is at least equal to or greater than the force of expansion and shrinkage of the first part of the carpet under the influence of cyclic temperature and humidity and loads from the movement of human traffic through the pile of the carpet.

The second part of the carpet is made of one or more layers of the following materials: (a) a woven material, nonwoven material, c) the foam and binder that is chemically compatible with/and placed between the layers to bind the layers together.

The second part of the carpet is made of the above-mentioned layer non-woven fabric and non-woven material is a fibrous layer and/or the fibrous layer is bonded or bonded by point bonding.

Binder for carpet forms a layer is slightly deeper than the top of the pile tufts, and the wrong side of the bottom layer is essentially covered with stitched through the bottom layer of loops. Hinges are fixed in the lower layer using a binder, priklauso this layer to layer, raspolojena the basis of carpet, containing bottom layer of nonwoven fibrous material having two opposite first back and the second hand, and intended for use in a carpet laid on the floor with additional hooks, siteplease the loops available on the wrong side of such a framework, with loops sewn in and substantially cover the first side of the lower layer and on the second side of the lower layer binder for fastening loops in the lower layer, the lower layer is made of polyester fibers, and on the second side of the lower layer is pre-coated to reduce the penetration of the binder in the lower layer.

The basis of the number and viscosity consistent with the density of the lower layer so that such binder penetrates on both sides of the lower layer to secure the loops in the lower layer; but without contamination of the loops on the first side and/or bottom layer stable point bonding, and/or a layer of foam attached to the fibrous non-woven material from outside loops attached to the nonwoven fibrous layer from the side opposite the hinges.

The Foundation is also characterized by the fact that the foam contains a cavity Il the AET also carpeted floor, having the main layer with pile, essentially covering the first side of the layer, while the pile is stitched through the core layer so that the left pile tufts on the second side of the base layer, and the first binder, coating the pile tufts to bond the pile with a layer of, for laying on the floor with additional hooks, siteplease the loops available on the reverse of the second side of the base, and the first side of the layer of the framework is attached to the second side of the base layer, and the reverse loop of the second side of the Foundation is fixed in the layer basics, in which the binder contains a cavity inside and around the pile tufts to ensure the expansion and shrinkage of the beams.

The second binder in the carpet surface is selected from latex, vinyl acetate and urethane, and a loop sewn in the bottom layer technology Malimo".

To achieve a technical result in the production method of the multilayer carpeting with top component of the pile and the bottom layer basics, vkluchaysya by embracing the connecting beams and pile fastening the first side of the base, containing loops to attach additional hooks on their second side to the reverse side of the upper component, and optionally included to determine the force of expansion of the upper component when the carpet is subjected to moisture, and a layer basis is chosen so that it was tough enough to be equal to or exceed a certain force of expansion of the top of the pile component in the assembled carpet, to essentially eliminate the expansion and shrinkage of the carpet due to absorption of moisture, when the carpet is laid as part of the loose installation, this binder contains a cavity inside and around the pile of beams, to allow expansion and shrinkage beams and/or binder is flexible in order to allow the extension surrounded by the connecting pile beams in such a way as to prevent substantially the extension of the carpet.

The method is characterized by the fact that there is a pile made of nylon and/or in which the definition of force expansion includes wetting the top of the pile component to enable the component expanded to its maximum width, the fixing component and in which the pile tufts secured in the upper layer component with a binder, and/or in which the layer framework includes a lower fibrous layer of non-woven material, and/or in which the hinges are fixed in the lower layer with a binder and coating placed on the bottom layer to reduce the penetration of the binder in the lower layer.

Variants of the present invention is described below with reference to the accompanying drawings, which depict:

in Fig. 1 is a cross - section of carpet made in accordance with the present invention;

in Fig. 2 - basis containing second layer of fibrous nonwoven material;

in Fig. 3 is an alternative framework that contains two additional layers of fibrous nonwoven material;

in Fig. 4 - alternative bases containing a layer of foam;

in Fig. 5 is a cross - section of carpet and bases made in accordance with the present invention.

In one aspect of the upper composite part carpet, made in accordance with the present invention includes a binder, which is applied on the wrong side of the main bases for fixing the inserted pile tufts in the base. Binder is selected so that it can absorb the swelling or rasshirennoi strength, to inform carpet integrity required for installation and use.

In preferred variants spanning the top of the composite part may be such that contains air trapped them to absorb the expansion of the fiber or binder may contain ordinary latex with less filler than is usually present in the latter case, the latex is more viscous and less rigid than latex composition applied in real time on the wrong side of the main canvas carpet. Generally true that the greater the degree to which a binder can absorb the expansion of the fiber, the less must be the atmospheric stability, which is required to create at the bottom of the base.

Carpet is considered to be stable in size, on the one hand, when the proposed expansion and shrinkage of the first part of the carpet, which consists of a felted fibrous part of the base layer and the binder to pile tufts from the bottom side of the base layer, the power stability carpeted second part, consisting of a preferably non-woven pretannage material made of polyester fibers, allogennogo material in each layer, specify what kind of material is injected: woven or non-woven material, thermally bonded, bonded at specific points or not, specify the weight of the binder and the coverage of pile tufts. If you use low weight of the binder, and if you created a cavity around the pile tufts, as a rule, less atmospheric stability that you want to create in the basis.

The generated layer 1 (see Fig. 1) preferably from the melt of the polyester fiber layer. This layer can be thermally bonded (for example, point bond) or not bonded, depending on the degree of stability required from this layer. In the layer sewn, preferably technology Malimo", loop 3, preferably made of polyester yarn. Hinges are fixed in the layer by applying a suitable binder 5, which preferably penetrates into the lower layer of nonwoven fibrous material sufficiently to cover the fiber loops around the layer, but not to penetrate into the loops, so as not to significantly reduce their ability to be interfaced with appropriate hinges, designed for fastening carpet during installation, as described in U.S. patent 4822658.

In addition, as shown layer 7 preferred nonwoven fibrous material of polyester fibers may be bonded to the first layer, to increase the dimensional stability of the Foundation of the carpet. Specifically, in the version shown in Fig. 2, layer 1 is relatively easy non-woven fibrous material, which is simply sewn layer of loops 3. Flashing weakens this layer and it is preferable to attach another layer 7 to provide dimensional stability. Glue or binder 5 is applied on the contour on the wrong side of the substrate, and then stack layer 7. A binder is used for fastening loops in layer 1, and to bond the layers together. Layer 7, which is relatively heavy in comparison with the layer 1 and significantly tougher, so all carpeted the composition has a consistency that is required for the installation and use of the carpet. Further, other layers may be attached, as shown in Fig. 3, to which is attached a second adhesive coating or binder 9 and the third layer is preferred fibrous non-woven material of polyester fiber.

Suitable fibrous non-woven material is one of the materials of the type described in U.S. patent N 4093763 and 4172166, or industrial manufactured by Akzo Nobel (the Netherlands), the material is called GOLBAG or manufactured by Freudenberg Spunwed Co. (in Darchelle could be first pre-coated before applying the layer of glue or adhesive 5, 9, to limit the penetration of the binder or glue inside the fibrous layers of nonwoven material, if so desired. This application can be significantly more effective in the case of layer 5 in order to prevent substantial penetration of the binder into the loop 3.

As shown in Fig. 4, a layer 13 of polyurethane foam may also be included as part of the carpet structure made in accordance with the present invention. It can be attached as to create elasticity and to increase the weight of the carpet. In this case, the binder 21 is applied on the underside of the main base and a fibrous nonwoven layer 41 of pretannage material put in line for direct bonding to it. The layer 13 of the foam can be applied directly in the path of mechanical or chemical foaming. Layer 43 knitted fabric containing closed loop 45 on the wrong side, impose on the contour of the layer of foam. In an alternative embodiment, the composition of the foam (which may be in the form of sheet material and knitted fabrics can be manufactured separately and may be used a binder for bonding Panora can be made in accordance with the present invention. It should be borne in mind that any of the bases shown in Fig. 1-4, can be used in the structure of the carpet, made in accordance with the present invention, if the expansion and shrinkage of the first part of the carpet, marked with the letter "A" in Fig. 5, when cyclically varying temperature, humidity (moisture) at least equal or exceed the specified resistance to expansion and shrinkage of the second part "B" of the carpet shown in Fig. 5.

As shown in Fig. 5, the first part of the carpet consists of a propylene base 15 and nylon pile 17, which was stitched through the Foundation, as a rule, continuous beam filaments.

This flashing leaves pile tufts 19 under the main base 15. The ability of these pile beams 19 to the expansion and shrinkage plays a significant role in the trend of the first part "A" of the carpet to the buckling temperature and humidity. Some form of binder required to achieve any degree of bonding of the pile, i.e. a situation in which the tufts of pile 17 of nylon, it would not be easy to pull from the base 15. Thus, the tufts of the pile 19 is surrounded in the minimum required degree svyatitele so, to layer 21 will not extend beyond the upper edge 23 of the pile tufts. This can be achieved partly through the use of a squeegee after application of the binder and before it is cured. The blade smoothes the surface formed by the upper points of the pile tufts and to a certain extent depressions 25 in order to minimize the amount of binder 21 on the first part "A" of the carpet. If possible, part of the cavities or spaces such as 25, may be left.

The second part "B" of the carpet has a base preferably of the spinning material of polyester. In that case, if the carpet must be laid in accordance with the system described in U.S. patent 4822658, substrate-the base must be integrated flash threads or loops 31. Such loops are usually fixed in the substrate 29 with a binder or adhesive 33 applied on the wrong side of the substrate 29 from the side opposite to the protruding hinges 31, and the second layer 35 pretannage material may be superimposed and attached to the layer 29 using the binder 33 or additional binder layer (not shown) may be applied after the junction 33 is already thermofixation. The entire second part "B" of the carpet is usually attached to the first hour usually do the minimum for to save part of the cavities or spaces around the pile tufts.

Depending on the method used for forming pile on the primary layer basics carpeting and style of carpet, a large number of nylon filament yarn placed under the substrate. The number of filament yarn, which leave under the base of the carpet, determine to a large extent, depending on the type of firmware used in the manufacture of carpeting. With direct suture 10-15% of the thread remains under the carpet, while at the patterned seam the number of threads can be 50% or more. In any case, if the quantity is calculated in accordance with theoretical extension or real tests, the exact degree of expansion and shrinkage under specified temperature and humidity of the first part "A" of the carpet can be determined. The preferred method is wetting the first part of the carpet with warm atmosphere and enabling the carpet to expand to a maximum width. The sample can then be locked in this position by the edges and can be determined force shrinkage.

When this force is known, the value of iostat this force, can be defined. The second part of the carpet can be tested for dimensional stability in a simple tension test by placing a part in the condition of stretching in any direction and application of traction.

The basis of the carpet may just be prepared, if required layers of fabric or non-woven material and is preferably bonded thermomicrobium, point bonding or non-point fastening spinning material, more preferably of polyester fibers. This material is flexible, easy and not hard, but it has the resistance to shear in the plane of the layer. The layer of sheet foam material or mechanically foamed material may also be padded.

As shown in Fig. 4, a layer 13 of foamed polyurethane may be included as part of the structure of a carpet in accordance with the present invention. It can be entered as to impart elasticity and increase the weight of the carpet. In this case, the binder 21 is applied on the wrong side of the main substrate and the fibrous layer 41 spinning material is placed in line to directly stick to it. The foam layer 13 may be applied neposredstvennostiu loop 45 on the wrong side, put in line on a layer of foam. In an alternative embodiment, the composition of the foam (which may be in the form of a sheet of foam) and knitted fabrics can be manufactured separately and may be used a binder for bonding foam and layers of the spinning material.
