Description

 The invention relates to the production of textile materials, in particular to the manufacture of fabrics blouse, shirts, underwear and children's assortment.

 Known fabric [1] made plain weave and containing a pair of spaced warp and weft, forming square cells with a constant density of warp and weft.

 The disadvantage of this fabric is the small size of the pattern, consisting of two warp and weft, located with a constant density, which reduces the consumer properties of the fabric.

 Closest to the proposed one is a combined weave fabric [2] containing warp and weft yarns arranged in groups with densified and sparse strips along the warp and weft, made by different weaves, and having at least two types of weaves in separate strips along the warp. The fabric pattern on the base is alternating densified and rarefied stripes. Some of the strips sealed along the base are formed by interlacing of satin 5/2, others by two interlacing: weft half-rips 1/3 or 3/1 with elements of shaped matting. Stripes sparse at the base are formed by the following weaves: plain and main half-rips 1/3 and 3/1.

 The weft fabric pattern is alternating, densified strips formed by weaves with weft repeat in separate strips equal to 36 threads. Duck-tightened strips are formed by interweaving: the main half-rips 1/3 and 3/1 with elements of shaped matting and satin 5/2. Stripes thinned through the weft are formed by weaves: linen, satin 5/2, weft half-rips 1/3 or 3/1. The densified strip contains 10 weft threads, and the sparse strip contains 26 weft threads. The cohesion coefficient of the densified weft strip is 3.6.

 The disadvantage of this fabric is its relatively low consumer properties, due to the reduced service life due to the loose structure, reduced strength and low cohesion coefficient of the compacted strip on the weft, which negatively affects the breaking load of the fabric on the base and weft.

 The purpose of the invention is the improvement of consumer properties of the fabric by increasing the service life.

 For this purpose, in a fabric of combined weaving containing warp and weft yarns located in groups with densified and sparse strips along the warp and weft, made by different weaves, and having in separate strips along the warp at least two types of weaves with a total rapport of the weft equal to 36 threads ; the weft rapport of each strip along the warp is no more than 8 threads, while all the compacted and rarefied weft strips are made by weaving corresponding to the weaving of the compacted and rarefied strips along the warp, and the number of weft threads in the compacted and rarefied strips is at least 4 threads.

 Comparative analysis with the prototype showed that the invention differs from it in that the rapport for the weft of each strip along the warp is no more than 8 threads, while all the compacted rarefied strips in the weft are made by weaving, corresponding to the weaving of the compacted and rarefied strips on the basis, and the number weft threads in compacted and sparse strips is at least 4 threads.

 Thus, the proposed fabric meets the criteria of the invention of "novelty."

 Comparison of the invention not only with the prototype, but also with other solutions in the art, allowed to identify in them the features that distinguish the proposed solution from the prototype, which allows us to conclude that the invention meets the requirement of conformity with the inventive step.

 The positive effect of this invention is achieved by increasing the cohesion coefficient of the densified strip across the weft, the presence of a repeat pattern of weaving on the weft of each strip along the warp of not more than 8 threads, the correspondence of the weaves of all compacted and sparse strips along the warp and weft, the number of weft threads in the densified and sparse strip of at least 4 threads.

 Figure 1 presents an abbreviated based on the pattern of weaving one of the classic fabrics of combined weaving "Kisei" art. 1436; in FIG. 2 abbreviated based on the weave of the proposed combination fabric.

 The combined weave fabric is made of threads arranged in groups with densified and sparse strips along the warp and weft, has a weft rapport of each strip along the warp of not more than 8 threads, while all sealed and sparse weft strips have weaves corresponding to the weaving of the compacted and sparse strips along basis, and the number of weft threads in the compacted and rarefied strips of at least 4 threads.

 PRI me R. The combined weave fabric was developed on the basis and the weft of cotton yarn pneumomechanical spinning method with a linear density of 18.5 tex. The fabric pattern at the base is alternating compacted A, B, C, E and sparse D, F stripes (figure 2). The strips densified on the basis are formed by the following weaves: band A weft half-rips 3/1; lane B satin 5/2, lane C weft half-rip 1/3, strip E weft half-rip 1/3, linen, weft half-rip 3/1.

 Stripes D and F, sparse on the basis, are formed by plain weaving.

The number of warp threads in the i-th strip is determined by the formula:
M _oi n _oi R _obi , where R _obi rapport based on the weaving of the i-th strip;
n _oi is the number of repetitions of R _obi in the i-th band.

Sealed and sparse strips on the basis contain the following number of warp threads:
lane A: M _oA 1-4 4 strands;
lane B: M _oV 1˙ 4 + 4 ˙5 24 threads;
lane C: M _oC 1 ˙ 4 4 strands;
lane D: M _oD 7 ˙2 14 threads;
lane E: 1 M _oE ˙10 10 strands;
Band F: M _oF 7 ˙2 14 threads.

 In addition, bands E and F alternate 3 times in the pattern repeat of the fabric.

The total rapport of the fabric pattern on the basis is M _oz M _oA + M _oV + M _oC + M _oD + +3 (M _oE + M _oF ) 4 + 24 + 4 + 14 + 3 (10 + 14) 118 threads.

 The weft fabric pattern is alternating, compacted I and sparse II strips. The densified I and sparse II stripes on the weft are formed by weaves with rapport on the weft of not more than 8 threads. In the proposed case, the largest weft repeat pattern in strip B is 5 threads. The densified I strip contains 10 weft threads, and the rarefied II strip contains 26 weft threads. The densified I and rarefied II strips along the weft are made with weaves corresponding to the weaves of the sealed A, B, C, E and the diluted D, F strips on the basis: weft half-rips 3/1 and 1/3, satin 5/2, linen.

The average density of the tissue on the basis is P _OSR = 220 n / dm. The density of the tissue in the weft in the compacted I strip is P _uI 500 n / dm, in the rarefied II band P _uII 200 n / dm.

 The cohesion coefficient of the compacted I strip in the weft is 8.5.

 An increase in the coefficient of cohesion of the compacted I strip in the weft by 2.36 times compared with the prototype has a positive effect on improving the physico-mechanical properties and durability of the fabric.
