Abstract

The invention relates to textile materials, in particular to multi-layered fabrics, which makes it possible to improve their performance characteristics by increasing the strength of the fabric to abrasion and adhesion during impregnation. The fabric includes upper and lower frame and filling layers consisting of main and weft threads. The main yarns are divided into two groups, one of which is intended to weave the filling layers only with the upper skeleton layer, and the other - only with the lower skeleton layer. Inside each group, the main threads are divided into two groups shifted by half a duck rapport and connected to the respective skeleton layers by a single-day weave. As a result, in the framework layers, the main threads are perpendicular to the surface of the fabric, which leads to the formation of funnel-shaped depressions on the surface of the fabric, which contribute to better adhesion during impregnation. 2 hp ff, 9 ill.

Description

The invention relates to textile laminates for various purposes, having good adhesion with synthetic materials.

The purpose of the invention is to improve performance by increasing the fabric's abrasion resistance and increasing adhesion during impregnation,

Figs 1-5 show the weave patterns of the invention according to the invention with the location of the weft yarns of the filling layers covered by the main yarns on the same level; Figures 6-9 are the same, with the arrangement with mixing of weft yarns of filling layers covered with main yarns.

Figure 1 shows a four-layer fabric. To obtain such a fabric, one system of main yarns and one system of weft yarns are needed. All main threads have the same training.

The rapport of the fabric on the base is equal to four different weaves of the main space, adjacent to the lower frame layer formed by weft threads with numbers 8 and 12, there is a fixing layer consisting of the main threads 1 and 3, which go to the upper frame layer.

Figure 2 shows a five-layer fabric. To obtain such a fabric, one system of main threads and one system of weft threads are needed. The rapport of the fabric on the basis is four yarns, the rapport of the weft fabric is ten yarns. The shedding process when weaving the weft yarns is the same as in the previous case.

Figures 3, 4 and 5 show similar fabrics consisting of six and seven layers. In these fabrics, the rapport on the basis is also equal to four strands, and the duck rapport is on twelve and fourteen whales respectively. The semilayer fabrics shown in Figures 4 and 5 are different from each other.

spun yarn, rapport of duck fabric - eight yarn. The main threads are divided into two groups: yarns with numbers 1 and 3 emerge onto the front surface - the uppermost frame layer of the fabric, and yarns with numbers 2 and 4 emerge onto the wrong surface - lower frame layer of fabric. When the weft yarn 5 is laid, the main threads 1 are raised and form the upper branch of the pharynx, all other main threads form the lower branch of the pharynx. When laying the weft yarn 6, the main yarns 1, 2 and 4 are raised, and the yarn 3 is lowered. When laying the weft 7, the main threads 4 are raised, and the threads 1, 2 and 3 are lowered. When the weft 8 is laid, the main threads 1, 3 and 4 are raised, and the threads 2 are lowered. When the weft 9 is laid, the main threads 3 are lifts, and the main threads 1, 2 and 4 are lowered. When the weft thread 10 is laid, the main threads 2, 3 and 4 are raised, and threads 1 are lowered. When laying the weft 11, the threads 2 are raised, and all the other threads are lowered. When weaving the weft yarn, 12 yarns 1, 2 and 3 are raised, and yarn 4 is lowered. In the space adjacent to the upper frame layer formed by weft threads 5 and 9, there is a fixing layer consisting of main threads with numbers 2 and 4, which exit to the lower frame layer of the fabric.

at stake -----. Weaving influences weft density and surface structure. The weave shown in .4 allows for greater weft density than the weave shown in Fig. 5, in turn, the latter weave has a more prominent surface structure, which contributes to better adhesion with synthetic materials.

The fabrics depicted in Figures 6 through 9 differ from the previous fabrics in that the anchoring layers consisting of warp threads are arranged obliquely with the displacement of the weft threads of the adjacent filling layers. For example, in the four-ply fabric shown in Fig. 6, the main thread 1 after reaching the upper skeleton is a flip-flop layer (weaving with its weft thread: and then skewing around the weft threads 6 and 11 located in the adjacent vertical filling layers In this case, the resulting fixing layers connect not only the vertical layers of the weft yarns, but also the horizontal layers of the weft yarns adjacent to the outer layers.

In the carcass layers, the main threads are perpendicular to the surface of the tunic, which leads to the formation of funnel-shaped depressions on the surface, which contribute to better adhesion during impregnation.

All fabrics were developed on a brand weaving machine with a tumbler carriage. As the basis used hlopkolavsanov yarn. Cotton was used as a duck.

The multi-ply fabrics depicted in Figures 1-9 can be produced from yarn and thread of any composition and type. These fabrics have high manufacturability, they can be produced on conventional weaving machines without the use of special devices and technologies. Fabrics have increased strength to the destructive effects of various types. Having a high filling with fibrous material, fabrics have a high resistance to the passage of liquids and gases, and after special treatment they can be used as an insulating material. In addition, fabrics can be used after appropriate finishing instead of duplicated fabrics, for example, in the manufacture of sports shoes.
