This invention relates to the field of textile materials and multilayer fabrics.

A multi-layered fabric is known, containing interwoven frame and filling layers, the latter of which are located along the weft threads of the frame layers and are interconnected in pairs 1.

The disadvantage of such a fabric is that the vertical filling layers are connected in pairs with adjacent layers, but there is no connection with the adjacent pairs of filling layers, therefore the overall strength of the fabric, ijQeHHO, in the longitudinal direction, V does not increase enough with increasing. the link filler layer. However, due to the fact that the operating time of two adjacent vertical filling layers occurs simultaneously, rapport grows 11 | duck replenishment and complicates the T1 technological weaving process.

Closest to the described invention by its technical essence, and the achieved result is multi-layered, contains intertwined frame and fill-in layers, the last of which have a weave of interlacing and are additionally interconnected by interlacing 2.

The disadvantage of this fabric is that the links between all the filling layers along the fabric are made by one branch of the filling base systems, and the second

10, the branch continues to produce filling layers and weak links are formed at the junction points. Therefore, the fabric has uneven strength in the longitudinal and in

15 vertical directions.

The aim of the invention is to increase the strength and dimensional stability.

The goal is achieved by the fact that a multi-ply fabric, containing intertwined skeleton and filling layers, the last of which have a woven weave and are additionally connected between

25 by itself, by interlacing, has a weave interlacing of the filling layers among themselves.

FIG. 1 shows one Russian

30 multi-layered fabric with one additional continuous connection between the filling layers in the middle of the fabric in height, with a longitudinal incision; in fig. 2 is the same, with three additional continuous links between adjacent filling layers; in fig. 3 - one-layer multi-layered fabric of increased thickness with three additional continuous links between the filling layers; in fig. 4 - two Russian multi-layered fabric with one additional continuous connection between the filling layers in each trench and reinforced tie-over in the middle frame layer, longitudinal section; in fig. 5 - one multi-layered fabric with additional continuous connections between the filling layers on each weft yarn, longitudinal section; in fig. 6 - one multi-layered fabric with two additional continuous bonds at the frame layers and one continuous connection between the filling layers in the middle part of the fabric, longitudinal section.

To obtain a single-layered multilayer fabric, four groups of filler base are needed — threads 1–4 and four frame groups — threads 5–8. Weft threads are indicated in the order of sequential introduction of threads 9–26 into the fabric. All filler layers are produced sequentially from top to bottom and in the opposite direction over the entire height of the fabric.

The weft thread 9 is interwoven with the filling main threads 1,2. When laying the weft yarn 13, a system of yarns 3.4 is put into operation and the weft yarn 13 is laid in the throat, formed by the yarns 1, 2 and 3, 4 of the filling base, where they are joined by a weave.

1 -D.B of this work, the threads 1,2 of the filler base are temporarily turned off and they are deflected to the upper part of the pharynx. The development of the lower part of the vertical layers continues with the filaments of 3.4 filling the base according to a given shedding program.

The weft yarns 14, 15, 16 are interwoven only with filler cores 3,4, and weft thread 1 is interwoven with filler 3J4 and skeleton 7.8 main threads Mif, the image of the lower skeleton link. By laying the weft yarns 17, 18 in the throats, which are formed by filling the main yarns 3,4 and 7/8 of the yarn, the accumulated area of the filling layer is connected to the fabric. This is followed by the next link in the filling layer. The weft yarns 19, 20, 21 intertwine only with the main filler yarns 3,4 and the lower part of the filler layer is formed, which is produced from the lower layer to the upper one. The weft thread 22 is interlaced simultaneously with both the filling threads 3,4 of the warp and the threads 1,2, which are re-activated, and the filling thread 3,4 of the warp is disconnected from the work after the weft yarn 22 has been laid. For this, the yarns 3.4 of the warp are deflected to the lower part of the pharynx.

At the time of incorporation into the process of tissue formation before the threads of the 1,2 filling layer are turned off, a bond is formed from these threads between the adjacent filling layers in the area between the weft threads 13 and 22. Further, the weft threads 23, 24, 25 are interwoven with the main filling threads 1 , 2 and forms the upper part of the second filling layer. The weft thread 26 is interwoven at the same time as with the filament threads 1,2 and with the skeleton threads 5,6. As a result, the top link of the second filling layer is fixed in the multi-layer fabric.

Next, the next link of the filling layer follows and the process of tissue formation is repeated.

As can be seen from this example, to obtain one additional continuous communication, it is necessary to have two main thread systems for the filling layers.

To obtain the fabric shown in FIG. 2, you need four filler base systems 1, 2, 3, 4, 7, 8, 9, 10 and two frame systems: threads 5, 6, 11, 12. The sequence of fabric production is carried out in accordance with the sequence numbers of the weft yarns 13,14,15, ... 30.

The nature of the interlacing of the base with the weft yarns, the sequence of switching on and off of the individual systems, the warp threads is determined by the program of work of the shedding machine (cardboard), which is prepared in accordance with the fabric structure produced.

In this example, as in all subsequent tissue structures, vertical filling layers are produced sequentially from top to bottom and bottom to top, etc.

The weft thread 13 is interwoven simultaneously with the skeleton threads 5.6 and the filling weft threads 1/2, forming the link of the upper skeleton layer. At the same time, the yaw-forming of the filling main yarns 1,2 and the upper frame yarns 5,6 is going on and the weft thread 13 is laid. The weft thread 14 n is interwoven only with the main filling yarns 1,2. When the weft yarn 15 is laid, the filling new system 3,4 is turned on, and the main threads 1,2 and 3,4 are interlaced with the weft 15. After this, the main filament yarns 1,2 are turned off. Thus, the weft thread 15 connects the two adjacent vertical links of the filling layer, respectively, developed respectively from the filling systems of the warp threads 1,2 and 3,4 and connects the follower and the previous vertical filling bases between the same threads of the thread. layers. The weft thread 16 is laid in the throat, which is formed only by filling the main threads of 3.4. The weft thread 17 is intertwined at the same time with two systems of filling the main threads 7.8, which are put into operation, and threads 3,4, which are turned off from work. Therefore, the weft thread 17 connects between each other two adjacent vertical links of the filling layer produced from the threads 3,4 and 7,8, the warp and is also connected by these threads with the subsequent and previous adjacent vertical filling layers. The weft 18 is only interwoven with the filling core yarn 7.8. The weft thread 19 is intertwined simultaneously with two systems of filling the main threads 9, 10, which turn on the work, and threads 7, 8, which are turned off from work. Therefore, the weft thread 19 interconnects the two adjacent vertical links of the filling layer, produced from the threads 7,8 and 9,10 of the warp, and is also connected by these threads with the subsequent and previous adjacent vertices of the filling layers. The weft thread 20 is intertwined only with the filling main threads 9, 10. The weft threads 21, 22 are laid in the throats, which are formed simultaneously by the threads 9,10 of the filling base and the skeleton threads 11,12, forms the link of the lower frame layer and attaches to the fabricated section of the fabric. After that, the next filling layer is produced from the bottom up. The weft thread 23 is interwoven with the filaments 9, 10 of the filler base. The weft thread 24 is interwoven simultaneously with two systems of filler backing — threads 7.8, which are put into operation, and threads 9.10, which are turned off from work, and so on. The process of tissue formation is repeated in the same sequence, but from the bottom up to the end of the rapport. In this structure, between the skeleton layers, three longitudinal continuous additional bonds are obtained, which are formed from filling core threads and are evenly spaced along the height of the fabric. In this case, to obtain three additional longitudinal links, four main thread systems are needed to generate filling layers, i.e. the number of additional continuous longitudinal links is obtained by one less than the total number of main threads for generating filler layers. Since the longitudinal links are evenly spaced along the height of the fabric, the average consumption of the filling bases is the same and they can be wound from one side. To produce the fabric depicted in FIG. 2, you need four filler base systems: threads 1, 2, 3, 4, 7, 8, 9, 10, and two framed threads, 5, 6 and 11, 12. The process of making tissue takes place in the order of numbering of weft threads 13,14,15, ... 38 tons. from top to bottom and then in the opposite direction. Since continuous additional communications are obtained evenly along the height of the fabric, the average consumption of the filling bases is the same and can be wound from one direction to another. To produce a multi-layered fabric, which is depicted in FIG. 4, you need four systems of filling the main threads 1,2,3,4,9,10,11,12. and three systems - 5,6; 7.8; 13.14. The filler layers of each tus are produced in opposite directions. The first filling layer of the upper russa is developed from the top down, and the bottom one - from the bottom up. Weft yarns are laid alternately in the upper and lower russes. Weft yarns are designated in the order of sequential introduction to the throat: threads 15, 16, 17, 40, 40. The weft yarn proklyudyvayut alternately in the upper and lower rus. The weft thread 15 is laid in the throat, which is formed by the threads 1,2 of the filling base and the threads 5, 6 of the upper frame, the base, and the link is formed; the upper frame layer. The weft thread 16: is laid in the throat, forming 11, 13 of the filling base and yarns 13, 14 of the lower frame base, and is formed. link of the lower frame layer. Then follows the laying of the weft yarn 17 in the upper rue, which is interwoven only with the filling main threads 1,2. The weft thread 18 is laid in the throat, which forms only the filling

bearing main threads 11, 12 lower rus. The weft thread 19 is interlaced with the filling main threads 1,2, and the weft thread

20 is intertwined with yarns 11, 12 of the additional base. Pointed thread

21 is intertwined simultaneously with two systems of filling the main threads 3,4, which are put into operation, and threads 5,6, which are turned off from work. Therefore, the weft thread 21 interconnects two adjacent vertical links of the additional layer, produced from the threads 5,6 and 3,4 of the base, and is also connected by these threads with the subsequent and previous adjacent vertical filling layers. Also, the weft thread 22 is intertwined simultaneously with two systems of filling the main threads 9, 10, which are included in the operation, and the threads

11, 12, which are turned off. The weft thread 22 interconnects two adjacent vertical links of an additional layer produced from the strands 9, 10 and 11, 12 of the warp, and is also connected by these threads with the subsequent and previous adjacent vertical filling layers. The weft thread 23 is interwoven only with the filling of the main threads 9,10. Pointed thread

25 is interlaced with thread 3.4 of the filling base, and the weft thread

26- with threads 9, 10 bases. The weft yarns 27, 28 are interwoven with the main filler yarns 3.4 and 9, 10, as well as with the yarns 8, 7 medium

-frame layer and fix the second filling layer in the middle frame layer.

Thereafter, the second filling layer is started up in the upper tier and up in the lower tier. When the stitching thread 29 is laid out of work, the filler base system is turned off — strands 9, 10, and it is interwoven with only filament filaments of 3.4. The weft thread 30 is interwoven with the filaments 9, 10 of the filler backing, which are reintroduced. The weft thread 31 is intertwined only with the filling main threads 3,4, and the weft thread 32 is interwoven with only 9, 10 filling bases. The morning thread 33 is intertwined with basic threads 1.2 of the filling layer, which are put into operation, and with main filling threads about 3.4, which are then disconnected from the work. Therefore, the thread 33 is interconnected between two adjacent links of the filling layer produced and the threads 3,4 and 5,6 of the base. These threads are connected to each other by the sequence and previous adjacent filling layers.

The same happens in the lower rus. When the weft yarn 34 is laid, the filling system of the warp is turned on - the yarn 11, 12, and it is laid in the throat, formed by the yarns 9, 10 and 11, 12 of the filling warp, interconnects two adjacent vertical links filler layer, produced from yarns 9, 10 and 11, 12 bases. Thereafter, the thread system 9.1 is turned off, and the weft thread 35 is intertwined only with the filling main threads 1, 2, and the weft thread 36 is laid in the throat, forming the threads 1 12 of the filling base. The weft thread 37 is intertwined only with the filler base 1, 2, and the weft thread 38 is interlaced with only the threads 11, 12 of the warp. The weft thread 39 is curved into the throat, which is formed by the threads 1, 2 of the filling base and the frame threads 5, 6. At the same time, the accumulated link of the top-layer filling layer to the fabric is attached.

The same happens in the lower rus. The weft thread 40 is laid in the throat, which is formed by the threads 11, 12 of the filling base and frame threads 13, 14.

When this occurs, the accumulated link of the filling layer of the lower rus is attached to the fabric.

In the shown multi-layered fabric, additional continuous connections are obtained in the longitudinal direction of the fabric in each race. As a result, with an increased thickness of the fabric, the strength and resistance of the fabric to destructive effects increase. The consumption of the filling bases is the same and can be wound from one side.

The fabric depicted in FIG. 5 is distinguished by high strength both in the transverse and in the longitudinal direction. Here, during the development of a link of a vertical filling layer, with each laying of weft threads between horizontal frame layers, a new system of filling bases is put into operation, and the previous one is switched off from the work, and so it continues until the end of the link.

Claims (2)

To produce such a fabric, sixteen main thread systems are needed. However, the number of frame yarn systems is always four. In this structure, additional links are formed in the Areas between adjacent weft yarns, both vertically and horizontally. Fabric with rapport weave 14 threads can be worked out on an automatic weaving station with a heald carriage, and with a large rapport on a weaving machine with a Jacquard machine. As can be seen from this structure, there are five additional continuous links between the frame layers, t. e. for each weft thread horizontally. The number of filler bases is six, i.e. the number of links is obtained by one less than the number of basic filler thread systems. The consumption of the filler bases is uniform and can be wound from one direction. To fabricate the fabric shown in FIG. 6, six filler backing systems are needed: strands 1,2; 3.4; 5.6; 7.8; 9.10; 11,12 and two frame systems: yarns 13,14 and 15, 16. The sequence of insertion of the weft yarns coincides with the sequence of fabric generation and proceeds as described. In this fabric structure, between the framework layers, there are five continuous longitudinal bonds. The additional connections are horizontally arranged lio to the height of the fabric unevenly but symmetrically, one is continuous communication in the middle of the fabric, and the other two are adjacent to the skeletal layers. In this case, for filling the foundations, two are needed. Fabrics with a thickness of 20-60 mm are developed on an automatic weaving machine with a heald carriage, and fabrics of greater thickness are developed on a loom with a Jacquard machine. Glass yarns, yarns and yarns made from natural and synthetic fibers, metal yarns, carbon yarns, and various combinations of materials are used as materials for making laminated fabrics. As a result of the fabric development of the proposed structures, the strength and dimensional stability of the tissues is increased two or more times, the weaving process is improved, as well as the weave weaving pattern. in this case, decreases. Claims of the Invention The multi-layered fabric containing interwoven frame and filler layers of the latter of which have a weave of webs and are further interconnected by means of interlacing, in order to increase the strength and dimensional stability of the filler layers between them.
