The present application priority is claimed on the basis of the provisional patent application US 61/017484, filed on December 28, 2007, to which reference means its full inclusion in the text of the present description.

The technical field

The present invention relates to the structure for use in industrial tissues, such as clothes for papermaking machines and technical fabrics. More specifically, this structure contains both elastomeric yarn (with elastic properties in longitudinal direction or in the axial direction), and relatively inelastic threads in different configurations. This structure has a high degree of compressibility at applying the normal load, as well as a significant capacity to recovery (resilience or the ability of the «springing») after the withdrawal of such a load.

Prerequisites for the creation of the invention

Industrial fabrics represent an infinite structure in a continuous loop, for example loop used as moulding, extrusion and drying fabric (clothes paper machine), as well as the technological tape, such as the ribbon for the Shoe press, calender, or conveying belt, used in the paper machine. Industrial fabrics also applies fabric used in textile finishing. Also to industrial tissues are other endless bands, for which the required properties is a high degree of compressibility and elasticity.

Although this mainly refers to the process of making paper, the use of the present invention is not limited to this application.

In the manufacture of paper fibrous cellulosic form canvas deposition of fibrous pulp, i.e. water-dispersion solution of cellulose fibres, moving on forming fabric in forming part of the paper machine. Through the fabric of pulp divert large amounts of water, leaving the surface of the fabric of fibrous cellulosic fabric.

thus canvas comes from the moulding part in the press section, in which the rows are pressing the shafts. Fibrous cellulosic fabric, supported by press tissue, or, as is often the place, situated between two such pressing tissues, passes through pressing the shafts. In these shafts specified canvas is subjected to compression, which leads to removal from it of the water and causes the adhesion of cellulose fibres, in result of which it becomes a sheet of paper. Press cloth or tissue take in water, which in the ideal case is not fed back into the paper sheet.

At the last stage of the paper sheet is sent to the drying part, which contains at least one number rotated drying drum or cylinder, heated steam from inside. Molded paper, tightly presses the drying cloth for surfaces of drums, consistently moves through a wavy path around each drum in a row. Heated drums reduce the water content of the paper sheet as a result of evaporation.

It should be noted that a kind used in paper-making machine forming, pressing and drying fabrics have the form of an infinite loop and operate on the principle of the conveyor. It should also be noted that the production of paper is a continuous process that runs at a significant speed, i.e. while forming part of a fibrous pulp continuously deposited on forming fabric, only made of paper continuously rolled into rolls on the exit of the drying part.

Woven basis and are a vital part of the above tissue can be made in different forms. For example, they can be obtained infinite textile ， or flat textile ， followed by giving them endless forms with the help of woven seam using at one layer of threads that are oriented in the machine direction and across the movement of fabric in the car. Also in those tissues can be used so-called shtyrevye seams, which also form of oriented in the machine direction of threads to be able to have on the paper machine. Besides, the Foundation can be made of layered by placing one basis inside an infinite loop, formed from other foundations, and their connection with each other or laminating each other using various well-known specialists of funds, such as through staple fiber through both the basics with their connection with each other.

In paper machine clothing, especially in the press tissues used in the press section of the paper machine, the fabric has at least one base, formed from yarns and programmed using a staple fiber normally at least in the contact sheet surface. Press the fabric has the original thickness, weight and the appropriate volume of voids of the estimated value of the volume based on the values of the mass and thickness), which corresponds to the capacity of water treatment. Also may be measured in the contact area of the press fabrics.

Because with the passage of at least one press shaft tight fabric is subjected to normal loads (relative to the plane of tissue during use) and because the fabric is made of compressible and contains compressible components, its volume of voids, and the area of its contact surface is reduced. While we have made various attempts to change the compressibility and increasing the degree of elasticity (springing or recovery) press tissues, forming tissue gradually turn out to be more thin over time and after the passage of millions of cycles pressing. Ultimately arises the need to remove them due to various reasons, for example due to insufficient capacity of water treatment, the appearance of labels and vibration occurs at pressing. Upon the expiration of their term of office they must be removed and replaced with new fabric.

For some time when using new fabrics their density and ability water treatment is less than optimal. Accordingly, the ideal of a press cloth is tight fabric having a permanent working characteristics (such as the ability water treatment) since the first days of its use before being removed from the paper machine.

Were made various attempts to change the properties of extruded tissue, especially compressibility and elasticity. For example, it was proposed to place in the structures of elastic thread. These threads have elastic properties in thickness direction or in the radial direction (in the case of circular cross-section), and may also have elastic properties in longitudinal direction or in the axial direction.

One such example is disclosed in international patent application WO 2004/072368 A1. However, the approach has some drawbacks. In this example, the compressibility provided only the elastic part of the thread (with elastic properties in thickness direction), and thus limited to this part. Although can also be used larger thread, this ultimately leads to a decrease in performance. Larger threads also have more weight and may lead to undesirable appearance of labels on the sheet. When using a string bicomponent type of core and shell there is a danger of retinal shell from the core. Finally, the degree of compressibility is limited to a maximum of some part of the thread diameter.

In a patent application, US no 2007/0163741 A1 revealed another example that uses an array of compressible threads bicomponent type attached to the back side sewn press fabrics. According to the disclosure of the said application shell is made of elastomeric and can provide reduced vibration. In addition, the core corresponds to the value of from 200 to 2000 denier, and the full size ranges from 0.3 mm up to 1,2 mm in diameter. Use threads of this size may be limited due to their weight and possible appearance of labels.

In U.S. patent №4,350,731 uncovered is one example where for the manufacture of compressible press fabrics are covered yarns. In this example, the degree of compressibility and recovery is also provided exclusively elastomeric layers covering of the shell.

Another example of a compressible elastic structures of this kind have been revealed in the GB 2197886. In this patent disclosed compressible thread, alternating in some way with functional threads, bearing load (stretching), and ensure applied under normal load formation of dense, essentially a single-layer framework, without thickening and long beams with obtaining essentially patterns basis.

Inclusion in the tissue elastic threads (with elastic properties in thickness direction or radial direction) to some extent, increases the elasticity or the ability of a «springing» these tissues after removal of the normal load. However, using these threads compressibility, and the ability to «springing» are also limited in the best case some part of the thread diameter.

As stated above, due to the limited elasticity new forming tissues are relatively high, exceeding the optimal value of the volume of voids for provision of water treatment. Then they are sealed and reach for some time optimal level of performance. However, after that, due to their limited elasticity they continue to shrink, which ultimately leads to the necessity of their removal and replacement.

Some special types of structures referred to , because threads, oriented in the machine direction, and threads, oriented across the movement of fabric in the car, not intertwined with each other, and placed perpendicular to each other in different planes.

Another example of a multilayer disjoint structure containing layers of functional threads that are oriented in the machine direction, and functional threads directed across cloth movement in the car, which are located in different planes 90 angle relative to each other, disclosed in U.S. patent №4,555,440. As in the above examples, this structure is referred to the incompressible due to the small thickness change in the application or removing the normal load. In one of the variants of realization of the specified patterns revealed one compressible elastic layer threads, to some extent, to ensure the availability of these features in the structure, otherwise incompressible.

The essence of the invention

In accordance with the above, the main objective of the present invention is essentially a compressible and elastic bases of in comparison with the basics of the art.

The present invention offered a supportive framework in which the elastomeric yarn (with elastic properties in longitudinal or axial direction) intertwined with the use of special drawing weave and used at least as a layer supporting base in clothes paper machines, industrial process tapes, tapes for textile finishing and other tapes, in which the required properties is a high degree of compressibility and elasticity.

In all of these embodiments of the used elastomeric filament with elastic properties in the direction of its length or in the axial direction. Elastomeric filament may also have elastic properties in the thickness direction. A thread can be performed in any suitable for application forms and can be, for example, a single , twisted , fiber coated with a thread of different materials, multicomponent thread, thread knitted, twisted thread or braided thread. Threads can be partially made of elastomeric material, such as in multicomponent thread in which as one of the components used elastomer material, or string can be entirely made of elastomeric material. It can be done twisted, twisted, knitted or braided. She may have a cross-section of a circular or any non-circular, including square, rectangular, elliptical and a polygonal shape. Examples of suitable elastomer materials include polyurethane, rubber or material under the trade mark «Lycra». Elastomeric filament can also have a cross-section made of any number of various geometric configurations, including round, , square, rectangular, elliptical and a polygonal configuration.

In the first variant of realization structure used most simple form, as described next. Layer (1) of threads used as the top layer is in the form of an array of parallel functional threads. As functional threads, you can use the thread of any known specialists type. For example, in the case of orientation in the machine direction or in the direction of the tissue in the car as filaments can be used thread, bearing tension load. As stated above, they can be made of any size, shape and famous specialists configurations on the basis of any materials to suit specific applications. As the polymer structure of the press tissue preferably use polyamide. The next layer (2) of threads is executed in the form of an array of parallel threads, oriented 90 angle relative to ply (1) threads. As the threads of this layer uses elastomeric yarn. The third layer (3) threads is also made in the form of an array of parallel threads, which are located on the opposite side of the layer (2) and are oriented perpendicular to the layer (2). The thread layer (3) are located in such a way that each of them aligned with the gap between two adjacent threads layer (1). These arrays threads are fixed to each other in some way. For example, they may be attached to the fibrous material layer, as indicated in the above-mentioned U.S. patent №4781967. In another variant of realization of the threads of one layer can be connected with the threads related layer in the place of their contact by well-known specialists glues, adhesives or thermal melting/welding.

It should be noted that the system (1) and (3) threads may be similar or different for material, configuration, forms etc. the Only requirement is to thread layer (3) were located in the intervals between adjacent threads layer (1) or Vice versa.

It should also be noted that the number of threads layers (1) and (3) do not necessarily coincide, and the number of threads layer (3) may be only a part from the number of threads layer (1) or Vice versa. For example, a layer (3) may contain only half the number of threads layer (1)that by using ensures the formation of gaps between the threads layer (3) and additional volume of voids/ability water treatment/ability water-selection. Another variant of implementation of the same algorithm variant of implementation, the use of woven binding threads. This structure at least on the contact sheet by well-known specialists of different ways can be additionally attached rapping.

In accordance with the above, the following steps are compressible elastic industrial fabric, thread containing focused essentially parallel to the direction of passing across the movement of fabric in the car, and threads, essentially parallel machine direction. Any number of threads, oriented at least one of the directions machine direction or direction across the cloth movement in the car, can contain elastomer material with elastic properties in the axial direction. All the threads of a single layer should be made elastomeric, for example in the structure, in which the series used the thread, oriented in the machine direction, threads, oriented across the movement of fabric in , and again the thread, oriented in the machine direction, all the threads oriented across the movement of fabric in the car must be met elastomer. The fabric can contain the first layer of parallel yarns, perpendicular to the movement of fabric in the car or in the machine direction; a second layer of parallel yarns, which is located on one side of the first layer and filaments which are one of the directions across the movement of fabric in the car or machine direction other than the direction of the threads of the first layer, and contain elastomeric yarn; and the third layer of parallel yarns, which is situated across the first layer the second layer and the threads of which are in the same direction as the threads of the first layer.

Parallel threads of the third layer are aligned so that they can be located in the intervals between parallel threads of the first layer. The fabric can contain any moral sense. In compressible elastic fabrics number of threads in the third layer is smaller than the number of threads in the first layer. Thread of the second layer can also be perpendicular to the threads of the first and third layers. Thread second layer of tissue can be arranged at an angle smaller than 90 degrees relative to the threads of the first and third layers, for example under an angle 45.

The proposed fabric can also include a fourth layer of parallel yarns, oriented in the same direction as the threads of the second layer, and containing elastomer material; and the fifth layer of parallel yarns, oriented in the same direction as the threads of the first layer, and aligned in the same vertical plane passing in the thickness direction, and that the thread of the first layer.

In one of the embodiments of fabric can contain a layered structure. For example, the fabric can contain two woven layer elastomer layer located between them. Another example tissue may contain connecting thread, twisted between the layers of the layered structure. In another variant of realization of the connecting and elastomeric yarn fabric pass in one direction, for example across the movement of fabric in the car. In this implementation, the layer of elastomeric yarns is located within a two-layer structure.

Compressible elastic fabric can be made in the form of whole cloth or a piece of cloth, selected from the group consisting of clothes for the paper machine, forming fabric, press cloth, drying cloth drying fabric for through drying air, the basis tape for Shoe press, basis tape for calender, the basis of technical fabrics, the basis of transport of the tape and the tape used for obtaining the nonwoven materials through means such as aerodynamic blowing from the melt, forming way of melt and threads. In case if the fabric is made as a basis for drying fabrics, dryer fabric can optionally contain the opposite direction on its contact surface, containing an angle extrusion tabs.

In another variant of realization of compressible elastic industrial fabric contains threads oriented across the movement of fabric in the car, and threads, oriented in the machine direction. Any number of threads that are oriented in the machine direction, and threads directed across cloth movement in the car, intertwined with the formation of woven material. Any number of threads contain elastomer material with elastic properties in the axial direction. The fabric can additionally include the linking thread. The fabric can also include 2-, 4-, 6-, 8- figure. Compressible elastic industrial fabric can be as tissue; the tissue obtained infinite textile，; and fabrics, made with the possibility of stitching being installed on a machine. In another variant of realization of fabric can contain a layered structure. For example, the fabric can contain two woven layer with elastomeric cloth, located between them. Another example tissue may contain connecting thread, twisted between the layers of the layered structure. In another variant of realization of the connecting and elastomeric yarn fabric pass in one direction, for example across the movement of fabric in the car. In this implementation, the layer of elastomeric yarns is located within a two-layer structure. The fabric can contain elastomeric yarn, made of rough basis, and connecting thread made of a smaller basis, than the base of elastomeric yarn. The fabric can also contain elastomeric yarn, oriented across the movement of fabric in the car, and threads, oriented in the machine direction and located on the top of elastomeric yarns; and the binding threads are made smaller than elastomeric yarn.

In another variant of realization of fabric can contain four end, woven from the top layer of elastomeric yarns so that after each second iteration figure layer connecting thread; and four end, woven from the bottom layer of elastomeric yarns so that after each second iteration figure layer connecting thread. The fabric can also contain one layer containing an elastomeric filament, and functional thread, passing in the same direction and elastomeric filament, and alternating with elastomeric filament; and elastomeric filament is made larger functional thread.

compressible elastic industrial can be performed in the form of whole cloth and a piece of cloth being selected from the group consisting of paper machine clothing; forming fabric; press cloth; drying fabric; drying cloth for air blowing; the basis tape for Shoe press the basis tape for calender; the basis of technical fabrics; the basis of the conveying belt; and the tape, which is used in the nonwoven processes, such as aerodynamic blowing from the melt, forming way of melt and threads. In case if the fabric is made as a basis for drying fabrics, dryer fabric can optionally contain the opposite direction on its contact surface, containing an angle extrusion tabs.

Detailed description of the invention

Although the following description refers to the press tissue, the present invention can be used as a tissue or tapes of other types, including drying fabric. As shown on the attached drawings, tight cloth has the first 10 or top layer of 12 containing an array of parallel functional threads 14, oriented in the machine direction. They can be made of any shape and size from any suitable material. This applies to all mentioned in the description of the threads.

The second or middle layer 16 threads 18 oriented 90 angle relative to the first layer 10. Threads 18 have an elastomeric characteristics as defined above.

It should be noted that during the use of fabric arrays threads in the layers of 12 and 20 can be oriented in machine direction or in a direction across the cloth movement in the car.

In another variant of realization of position and orientation of the layers of 12 and 20 of each other and/or the magnitude of the gaps between them are chosen the same as the above option implementation, however layer 16 oriented angle smaller than 90 degrees relative to the layers of 12 and 20, preferably at an angle of 45 degrees.

In another variant of realization used the principle similar to that described above, however, the structure formed by the method similar to that described in under joint consideration of the application, US no 11/893874, a link which means its full inclusion in the text of the present description. According to this method, form the full length and width of the array are oriented in the machine direction functional threads (for example, thread, bearing tension load). To this array has added another layer of necessary elastomeric yarns, transversely oriented cloth movement in the car. These focused across the movement of fabric in the car threads can be perpendicular or at an angle smaller than 90 degrees relative to the threads that are oriented in the machine direction. At the subsequent folding fabric according to the manner revealed in the present application, the layers of 12 and 20 threads form to accommodate between the two layers 18 elastomeric yarns that can be placed perpendicular to each other or crossed at a sharp angle. The magnitude of the gaps between oriented in the machine direction threads selected so as to ensure the possibility for accommodation threads in these intervals. Using the proposed fabric as the press fabrics for additional bonding patterns at least to one of the surfaces can be attached additional fiber.

In another variant of realization of the structure formed by the way, a similar method is revealed in the above-mentioned U.S. patent №4555440, the link on which means its full inclusion in the text of the present description. For illustrative purposes, figure 1 shows only two layers of 12 and 20 threads, oriented in one direction and one layer of 16 threads oriented perpendicular to that. Structure built by weaving the similarity 24, as shown in figure 1. It should be noted that such woven binding threads can be in the machine direction or across the movement of fabric in the car. Thread layers of 12 and 20 are in the form of functional threads. If they are oriented in the machine direction, at least one of the two layers can contain thread, bearing tension load. They can be made the same or different from each other in terms of shape, configuration, material, etc. Layer 16 formed of elastic filaments. As above, the magnitude of the gaps between matching threads 14 and 22 choose so, to provide the possibility for accommodation threads in between. The binding threads of 24 may be in the form of similarity or also in the form of a functional of threads that can positively influence, for example, on the stability of fabric in a direction across the cloth movement in the car. As in other of the above options for the implementation of the proposed fabric as the press fabrics for additional bonding patterns at least to one of the surfaces can be attached additional fiber. In addition, depending on the application instead of padding to the structure can be attached microporous film.

When the load perpendicular to the plane of tissue layers of 12 and 20 threads move one towards the other and placed in between, which provides compression of the main fabric almost to the full diameter of the thread. However, more important is the fact that after removal of load elastic filament 18 «»that leads to the displacement of layers of 12 and 20 from each other.

In addition, as described in the patent '440, you can use more than two layers of functional threads that are oriented in the machine direction, and more than one layer of threads directed across cloth movement in the car, as shown in fig.4. When using, for example, three layers of threads that are oriented in the machine direction, two layers of the three should be located on some distance from each other for the hosting of threads in between. For example, upper and middle layers can be oriented in such a way that the threads in the middle layer are in the interval between two adjacent threads upper layer and the thread in the lower layer is laid in the direction of under the top or middle layers. In addition, two layers of threads directed across cloth movement in the car, can be performed elastomer. In one variant of realization of only one layer can be formed elastomer, and another layer can be made of functional threads to increase stability in a direction across the cloth movement in the car or providing a larger volume of voids under load. As above, the threads in the upper, middle and lower layers can be made the same or different from each other in terms of shape, configuration, material, etc.

In figure 4 The shows another option woven structure in which the fabric 10 contains five layers, which are essentially in parallel planes and each of which contains a parallel thread. Thread in the first, third and fifth layers (i.e. layers 12, 20 and 28) are oriented in the machine direction, and the threads of the second and fourth layers (i.e. layers of 16 and 26) are oriented in the direction across the movement of fabric in the car. As shown in the drawing, oriented in the machine direction threads 22 of the third layer 20 is located, as described above, at some distance from each other in between threads 14 of the first layer 12 and the fifth layer 28. The second layer 16 and fourth layer 26 contain elastomeric yarn 18. The binding threads of 24 oriented across the movement of fabric in the car.

Layers are not intertwined. At least one relatively thin thread of 24 used for the connection of layers in the vertical direction. For example, for the connection threads of the Central or middle layer with the top and bottom layers can be used two threads 24' and 24”. This configuration provides a lack of lateral displacement of the individual threads in layers. The binding threads of 24' and 24” can alternate from one row to another row, each of which passes in a direction across the cloth movement in the car.

For the manufacture of spiral permed strips of material to provide a structure described in U.S. patent №5360656, can be used patterns of the same type as described above.

All of the above structure can be performed endless in the machine direction. They can also have seam to provide opportunities for stapling are being installed on a machine. One of the ways of formation of a seam in structures is described in U.S. patent №4979543.

In this case, it should also be noted that elastomeric filament can be used in layers, oriented in the machine direction, layers, transversely oriented cloth movement in the car, or layers of both types, provided that there is at least one oriented in the machine direction layer threads, bearing tensile loads to ensure the required strength and resistance tensile structures throughout the time of its use.

Compression/elasticity depends on the elasticity required threads, the size and number of threads, the number of layers of threads and, obviously, directly from the whole structure. The structure according to the present invention can also be performed as part of a layered structure containing other arrays or threads basis.

On 6 shows a 2- with weft thread thickness of 0.35 mm; the diagram shows the threads 18, 24 with two different densities. For 2- surface, for example, for a 5-layer fabric with elastomeric filament 18 can be used 16- figure (16/4=4, 4/2=2 Zev). In the case of fabric stitched being installed on a machine, as the top drawing, you can use 2- figure for fingered threads. As weft thread to stitch threads in 2- figure you can use the same thread, and that, for example, in a 4- figures, to maintain strength loops. As another example, when 2-layered 4/8- textile, you can use a four twisted thread as a duck.

In other embodiments of the patterns shown in Fig.7, used multicomponent twisted thread containing elastomer material 16, for multilayer fabric with two-layer configuration. On Fig.8 shows the options for the implementation of layered structures tissue. On fig.8 shows the structure of the basics of thread 18 and threads 14, 20, placed between two layers of fabric.

On In Fig.8 shows woven basis. The Foundation contains the thread of 18 and threads 14, 22, and thread 24. There might also be other options for implementation as of elastomeric yarn use crochet thread instead of yarn.

According to yet another variant of the implementation shown in figure 9, compressible elastic five-layer fabric contains connecting thread 24 oriented across the movement of fabric in the car. An array of 16 threads, thread containing 18, passing across the movement of fabric in the car, is situated between the first array 12 and the third array 20. Thread fourth layer 26 containing threads 18, located in alternating between a vertical plane relative to the parallel elastomeric yarns second layer 16. Threads 14 of the fifth layer 28 are located in the same vertical plane that thread and 14 of the first layer 12. As shown on the drawings, each thread 24 alternately intertwined top and bottom three parallel threads in the first and fifth layers and placed at some distance in the machine direction so that the formation of the long overlap with each of threads 12 of the first layer 12 and the fifth layer 28. As shown on the drawings, elastomeric yarn located within a two-layer configuration figure weaving, which can be used 16 shaft guidance for the case of infinite textile and 8 shaft guidance for the case of a flat weaving. In the tissue under this option implementation, you can use single warp monofilament -, four twisted thread or the threads of other types. You can also use two different warp, more rough framework containing the thread of 18, and less so the basis for threads 24. Fabric structure, shown in figure 9, is used with two separate . However, in the absence of the necessity to obtain the two bases, paper/structure may also contain small connecting thread with elastomeric warp and cross-thread, woven from the top of elastomeric warp.

Interweaving should provide tensile elastomeric yarns and compression basis under the action of normal load and its «springing» after removal of load.

Figure 10 shows another variant of implementation, according to which weave the threads of the basis. As shown in figure 10, the end of the four threads 14 of the first layer 12 woven from the top layers of 16, 22, 26 threads 18 so that after each second iteration figure layer thread, and the end of the four threads 14 woven bottom layers, 16, 22, 26, so that after each second iteration figure layer connecting thread. Each layer should be elastomeric yarn. The thread may or may not be present depending on the required degree of compression.

Figure 11 shows another variant of implementation. Fig.11, 11C and 11D illustrate uncompressed position, and fig.11 and 11TH illustrate compressed position. The drawings one layer contains elastomeric yarn 18 shown in the form of elastomeric weft threads 18, and functional thread 17, passing in the same direction and alternating with threads 18. Elastomeric filament is made thicker thread 17. As shown on the drawings, threads 18, 17 may take place in the machine direction; a layer of tissue may also be executed with the possibility of including more major strands of 18 in the direction of the basics, such as, for example, in multi-axial fabrics. As shown in the drawing, in comparison with the variants of realization shown in fig.11D and NOT, inter alia, the fabric is made of compressible and firm even when a single-layer configuration. In addition, by changing tensions duck and bases can be obtained smoother thread oriented across the movement of fabric in the car and crossing elastomeric yarn.

On fig.12-12TH shows another variant of implementation of the tissue in which fabric is made with curves, oriented to a greater or lesser extent in the machine direction, and contains elastomeric yarn in inner layers. The dimensional drawings represent three layers of 12, 16, 20 elastomeric yarns 18; the top layer of 12 and a bottom layer of 20 pass in a direction across the cloth movement in the car, and the middle layer 16 longitudinally placed in the machine direction. Tripper or binding threads 24 (fabrics, stitched being installed on a machine) pass through the structure or woven into it, as shown on the drawings, with outer surface of the filament 24 are top-oriented across the movement of fabric in the car elastomeric yarns layer 12 down with the formation of the loop from the bottom of one oriented across the movement of fabric in the car threads 18 in the bottom layer of 20 array of elastomeric yarns and then back up. As shown on the drawings, the binding threads of 24 made of curved 30.

In the options for the implementation shown in figure 11 and 12, as well as in above-mentioned cases, interweaving and placement of elastomeric yarn is selected such that the base shrinks at Annex to the normal load, and the «springs» after its removal.
