Technical two-layer fabric for the production of footwear made of cotton polyester yarn with a linear density of 38 • 3 tex, characterized in that, within the weaving pattern, each first weft thread has three main floors, and the next weft thread has one main floor, the layers being tied individual warp threads or through dressing with all warp threads passing from layer to layer. 2. The fabric according to claim 1, characterized in that the yarn is composed, in%: Dacron - 25 ± 5 Cotton - 75 ± 5e

Description

Technical two-layer fabric for the production of shoes

The proposal relates to weaving and can be used in the production of harsh two-layer fabrics used as a fabric basis for the manufacture of artificial leather for the tops of tarpaulin boots.

Known severe two-layer fabric fabric for the production of tarpaulin according to TU 17 RSFSR-D18-102-0005-91 from cotton-polyester yarn. The main requirements for the fabric are strength and abrasion resistance, as well as the ability to impregnate and stiffness.

The challenge facing the claimed utility model is the creation of lightweight fabrics, sparse on the basis or item: from: su.

This result is achieved by the fact that in the two-layer fabrics lightweight for the production of shoes made of cotton polyester Fiber yarn with a linear density of 38x3 tex within the weave pattern, each first weft thread has three main overlaps, and the next weft thread has one main overlap, while the layers are tied with separate threads adjacent warp layers or through dressing with all warp threads passing from layer to layer. The yarn has in its composition in%:

Drawings are depicted on:

Figure 1 is a repeat of the weave and cross-section of the fabric with ligation of the layers separately; strands of adjacent layers OCHOE.LI,

figure 2 rapport of weaving and cross-section of fabric with a cross dressing with all warp threads passing from layer to layer.

The proposed weave is used for single-fuel dressing, since all the threads involved in the weave have the same work time.

The fabric is produced on ATT 120-5M or STB type machines.

Figure 1 presents the pattern of weaving fabric with a bandage of individual threads of adjacent layers of the base. As can be seen from the figure, the dressing of the layers is carried out by 3 and 4 warp threads within the same rapport, then to 1 and 2 warp threads are each located in its own layer. This fabric is basic.

According to the test results, with a decrease in the surface density of the fabric by 110 g / m2 as compared with the well-known serial fabric according to TU 17 of the RSFSR-D18-102-C05-91, the strength of the weft remained the same, the strength of the backing decreased by not reducing the density of the backing.

Figure 2 shows the structure of a two-layer fabric with through dressing. All warp threads pass from one layer to another, while maintaining a given pattern of weaving. In this interweaving, compaction of the layers occurs at the intersection of adjacent warp threads. As can be seen from the figure, the warp thread 1 goes around the first weft and then goes into

 ate. tissue and in such a way all whales smallpox gastuguy formation of both one and the second layer of fabric.

According to the test results with a decrease in the surface density of xivaHH by y and g / m2 as compared to the serial production ... -. remained the same, and the strength of the base decreased disproportionately to the decrease in the density of the base.

Similar results were obtained with a decrease in the surface density of the fabric by 190 g / m2 and 210 g / m2 due to the unloading of the fabric both on the basis and on the weft with the indicated repeat patterns.

Example 1

Cotton polyester yarn 38x3 tex.

In rapport, the first weft thread has 3 main overlaps, the second one.

Bandaging of layers - with separate warp threads of adjacent layers.

The number of warp threads is 265.

The number of weft threads is 211.

When tested, the tissue obtained the results;

Fabric Width - 90.2 cm

Turning density - 618 g / m2

Base strength, Ro - 85.6 kg / 2cm

The strength of the duck, RU - 67.5 KG / 2SM

Elongation at break: based - 22.6%

duck -11.2%

Example 2

Polyester yarn yarn 38x3 tex.

In rapport, the first thread has 3 main overlaps, the second one.

When fabric was tested, the results were as follows: Fabric width - 91.5 cm The highest density - 637 g / m2 Base strength - 85.2 kg / 2cm

Duck Strength - 66.3 KG / 2SM

Elongation at break: based - 24.7%

duck 10%
