Abstract

SUMMARY OF THE INVENTION: the method provides the formation of fabric with a variable density along the basis of the length of the fabric on a loom. The main threads are divided into two systems according to the width of the fabric. Each of the systems is worn out from separate groups of threads. Section (sleigh with different densities according to ibCHqae are formed due to the increase in Shell a.

Description

The invention relates to the weaving of the textile industry and relates to fabrics with a variable density on a warp basis produced on weaving machines.

The purpose of the invention is the expansion of assortment capabilities by producing fabrics with a variable density of warp yarns along the length of the fabric.

The positive effect of using the proposed technical solution is to increase the efficiency of the method, expanding the range of produced fabrics with the effect of variable density along the base along the length of the fabric.

PRI me R practical implementation of the method,

It is required to produce tissue with a variable density on the basis of a motive cartridge (Fig. 1). Each cell of the motive cartridge is a piece of tissue formed by a group of warp and weft threads. All warp yarns are divided into groups, and they can be moved both vertically and horizontally. For groups of the first warp system, we introduce CTof, and for groups of the second warp system, 0 |. The numbering of tissue sections in the rapport of the motive cartridge is shown vertically. Suppose that each group of the first and second main systems, the threads inside itself has the same raft (L

Consider the implementation of the method of forming this fabric and the weaving machine (FIG. 2 and FIG. 3) D -; .:: -.,.

Fabric 1 (FIG. 3) has .I-1X lengths and consists of groups of the first system 2 of the main fabrics and groups of the second system 3 of the main and weft threads (not shown in FIG. 2). The groups of the first system of 2 main threads (CTt,: STa) and the groups of the second system of 3 main threads (Oi, Oa, Oz) are wound from weaving, navo; they go around the rocks about and make their way into the lamellas (not shown in FIG. 3.). After the lamellas, the groups of the first 2 and second 3 systems of the main threads are pierced into the eyes of the galevs of remiz 4, directing heat. benki 5 and reed (not shown in FIG. 3). Laying of weft threads, their surfing to the edge of the fabric and removal of the produced fabric is carried out in the usual way for a loom (not shown in Fig. 3), i

During the formation of section 1 (Fig. 2) of fabric 1 (Fig. 3), all groups of the first 2 and second 3. The main thread systems are moved in a vertical plane in accordance with the law of weaving with the eyes of hedge hems 4. In this case, the warp threads are intertwined with weft and form tissue sections with a density of Poi .120 n / dm. , When forming section II of tissue T, the groups of the second system of 3 main threads: 0i, Оа, Оз are moved in the vertical plane with the eyes of galevs of remise 4. The groups of the first system of 2 main threads of ST- and STa are moved in the vertical plane with the eyes of galevs of remise 4. At the time of the first the length of these yarns in the upper or lower positions of the group of the first system 2 of the main threads CTi and CTa is moved horizontally by the guide combs 5, the CTi group to the left to the group of the second system of 3 main threads 01, the group of CTgs to the right to the group of yarns, ОЗ; , then the groups of warp yarns CTi and STa are moved in a vertical plane by the eyes of Remise 4. When weaving with weft yarns in the Ot and Oz sections, sections with a plane based on the Poa 240 n / dm are formed, in the 02 section with RSI 120 n / dm, sections CTi and STa with ROO 0.

When forming section III of fabric 1 of the group of the second system, 3 of the main threads Oi, Oa, Oz and the group of the first system of 2 of the main threads cfi, СТа are moved in the vertical plane with the eyes of galevs of remise 4. When weaving with the weft threads, the warp threads of the first 2 and second 2 systems form III tissue sections 1 similar to II regions. When forming IV tissue region 1

0. The groups of the second system of 3 main strands of Or, Oz are moved in the vertical plane by the eyes of the galev remis 4. The groups of the first system of 2 threads of the warp CTi, STa and rpiynny of the second system of 3 warp threads of Oa are moved in the vertical plane by the eyes of the gummy remise 4. At the moment the first length of these yarns at the highest or lower positions of the group of the first system of 2 warp threads ST-), STa and the group of the second system 3 of the warp threads Oa are moved in the horizontal plane by guide combs 5, the group CTi to the right to the tissue site CTi, the group STA left on chastok CTa tissue Og group to the left group

5 strands Then the groups of warp threads SP, STa, 0.2 are moved in a vertical plane with the eyes of the galev remiz 4, When weaving: weaving warp threads with weft threads. . tissue sections are formed; Oi, CTa, Oz with

0 p di 120 n / dm, CTi with Roa 240 n / dm, Oa with Roa 0,: ..... - .. ,, ..., -. ; .- :. Similarly, in accordance with predetermined motive cartridge (Fig. 1), portions V-IX of tissue T are formed.

5 The structure of the fabrics obtained by the proposed method is a fabric that along the length has sections with different warp densities, fixed with weft threads / Patches with different warp densities are formed by increasing the number of warp threads when moving groups in the horizontal plane threads of the first and second systems of the main threads relative to one of the sides

5 adjacent groups of warp threads.

Using the proposed method allows to expand the range of produced tissues with the effect of a pregnant density of the main threads along the length of the fabric.
