Abstract

The invention relates to the textile industry and reduces the breakage of additional warp threads during weaving. The method consists in feeding the warp yarns from the spool core, determining the processing of the warp of the warp threads and the warp threads when weaving and winding the warp thread onto the warp shaft with a length shorter than the warp threads, based on the following YYPCP - Y. - the length of the additional C (1 - 56) warp on the warp shaft; cf is the average length of the background warp threads on the warp shaft; Yt is the training of an additional warp in the fabric; YC - average processing of background warp threads in fabric. 3 з.п, ф-л, 2 Il.

Description

The invention relates to the textile industry and relates to a method of forming a weaver.

The aim of the invention is to reduce the breakage of the warp threads when weaving - by preventing the sagging of additional warp threads of a different nature.

Figure 1 shows a portion of a bore; Fig. 2 shows a device for operating the warp on a warp shaft for shuttleless looms.

The device for making the basis for weaving machines includes spool pins 1, row 2 and warp shaft 3 with pressure rolls A and 5. In the case of forming the basis for shuttleless weaving machines and eliminating breakage only due to slack in the edges, additional pressure The rolling rollers 5 are tapered and installed at the end sections of the warp shaft 3 (FIG. 2). The background and additional threads are fed from the spool I and wound on the warp shaft. 3 Thus, several warp rolls are formed. Then the threads from several warp shafts are wound on a weaver's heel, which participates in the formation of the fabric on a loom “After the weaving process, the processing of additional warp threads is determined. Based on the formula

If necessary, the formation of striped fabrics from strips of different fiber nature, for example, flax and cotton according to Art. 03 180 (toweling fabric with colored stripes), determines the cutting of linen yarns (additional threads ) and the processing of cotton threads (background threads),

In the case of fabric formation on the shuttleless loom, where the base has the same nature of fiber, determine the processing of the warp threads in the middle part of the fabric and the processing of additional threads in the edges of the fabric.

The winding of the base warp yarns and additional yarns onto the warping shaft, having different lengths, is carried out by pressing additional nty (working less than cutting the background yarns) at a pressure of 1.5-1.8 kg / cm and (or | the increase in tension of additional warp threads by 15-25% compared with the tension of background warp threads.

When making the basis for shuttleless weaving looms with the same

In the base, the length of 1/10 of the warp threads in the edge portions of the warp shaft is successively reduced by 1-2% in the direction to the ends of the warp shaft compared to the length

warp threads and in the middle part

of the warp shaft. In this case, the pressing of the edge threads of the base is carried out by conical pressure rolls 5, tapering

which is 0.03-0.07 and located at. end sections of the warp shaft, and an increase in the tension of the edge threads of the base is carried out on the corresponding nitenate inhabitants 6 o

Example 1: The production of linen bag art, 15 258 from 280 Tex yarn was carried out on an ATPR-120-LM machine, the length of the warp wound 1200 mm, the most extreme warp threads in the edges are 5%, and The average base cutting in the middle of the fabric was 7%. The length of the extreme warp thread in the edges is determined from the ratio of 1200 Top

Thus, the length of the first and last warp threads is less than 2%.

the lengths of the warp in the middle. The number of threads on the warp shaft 190 The distance between the flanges of the warp shaft is 140 cm. The bulk was formed from four warp rollers. The number of threads at the front was 760 threads, and the distance between its flanges was 1–20 cm.

Example 2, Production of linen smooth fabric with color strips of cotton and flax type art 03 180 on a STB 2-180 machine in 3 canvases. The maximum width of the dressing by Byrd is 56 cm for each blade. The number of warp threads in each canvas is 834, the total of 2502 warp threads, including linen threads 96 tex - 1339, and cotton tex - 1163, the distance between the flanges is 180 cm.

The length of the background yarns (cotton yarns) is required. On the warp shaft, it was 1600 m, the cotton yarn was 12.3%, the linen yarns were 7.4%, therefore the length of the additional yarns on the warp shaft (flax yarns) should be be

The proposed method makes it possible to create conditions for the normal production of 15 fabric from strips of threads based on the different nature of the fiber, which was not possible in traditional methods.
