(54) METHOD OF SMOOTHING YARN FROM CELLULOSE FIBERS

The invention relates to the textile industry, in particular, to the technology for the processing of blue bulbs.

An important step in preparing the foundation for weaving is the physicochemical process of yarn sizing. In case of polymer composition, the supramolecular structure of the yarn changes. To ensure that the breakage in weaving is reduced and the quality of the foundations is improved, the choice of the most optimal sizing methods and methods that reduce friction, electrifiedness and increase strength and resistance to wear is of great importance.

npSDKH.

Nowadays, it is very acute. (The issue of processing from low-grade raw bag sack {a X p and l, which in their structure is very loose, loaded with 1 material, is very hot during processing and has a significant breakage in weaving, which leads to a decrease in production).

bones of labor in weaving shops, deterioration of the quality of fabrics.

Closest to the present invention is a method of sizing the bases, according to which the yarn is treated in the first bath in an aqueous medium prepared from rosin-sodium soap and fat-wax (stearin, paraffin), pressed between the shafts and wet into the second jsaHHy with dressing

10 with a solution of acetic acid potassium, starch and other fillers. After that, the yarn is pressed between the shafts to be dried as usual.

The disadvantage of this method is obtaining yarn with high rigidity, brittleness and low resistance to abrasion.

The purpose of the invention is to reduce the breakage of yarn in the process of weaving.

This goal is achieved by the method of sizing of cellulose fibers, which includes pretreatment in an aqueous medium.

spinning, impregnation with starch dressing, spinning and drying, pretreatment is carried out at 6 ° C-7 ° C in the presence of 0.3-O, 5 g / l of ethoxylated alkyl acetate and followed by pressing

up to 50-8O%.

Example. Flax cotton batten no. 5 is pretreated in the first bath (module 1:10) containing O, 3 g / l of oxengshgarted a kilphenol at 60 ° C, then squeezed between shafts to a moisture content of 50-80% and raw yarn is dipped in the second bath (module 1: 1O) with a sizing composition containing, g- / p: starch 40, chloramine 0.125, borax 1, glycerin 2, water to a liter, then re-squeeze and dry. .

Example 2. ./5. The battered yarn # 5 is pretreated in a first bath (module 1:10) containing 0.4 g / l of ethoxylated alkyl phenol at 6 ° C. Then they squeeze between the shafts to a moisture content of 5О-8О% and the wet yarn is immersed in a second bath (module 1:10) with a dressing composition containing, g / l: starch 40, chloramine 0.125, borax 1, glycerin 2, water to liter then re-squeeze and dry.

PRI me R. 3. Linen batt yarn No. 5 is pretreated in the first bath (1: 1O module), containing an increase of 18 Compact low-growth 8 Increase 17,, 2 Increase, 15 Increase. 16 Increase 17.2 27% reduction in bristle bristle 31-32

0.5 g / l of ethoxylated alkylfecop at 60 ° C, then squeeze between shafts to a moisture content of 5–80% and the raw yarn is immersed in a second bath (1:10 module) with its composition containing, g / n: Crasogsal 4O, chloramine 0.125, borax 1, glycerin 2, water to liter, then re-squeeze and dry.

Primer 4, Flax combing yarn NP 5 is pretreated in the first bath ((1: 1O module), containing 0.4 g / l of ethoxylated alkylphenol at 65 ° C. Then it is processed as in Example 1.

P p i. measure 5. / b of the naked batt yarn no. 5, but it is treated in the first bath (module 1:10), containing 0.4 g / l of ethoxylated alkylphenol at 70 ° С. Then there is a processing as in example 1.

The proposed method is used for dressing flax flakes yarn. In parallel, sizing of the bases is carried out by a known method.

The processing results are shown in the table, where examples 1-5 are proposed, and 6 are known.

As can be seen from the table, the proposed method of dressing provides an increase in the strength of yarn by 15-2%, increases resistance to abrasion by 2 times and reduces breakage. 1511 0.13. 0.13 1511, 0.129 Mass 5931 Claims for dressing yarns from whole-grain fibers by pre-treatment in an aqueous medium, pressing, impregnating with starch dressing, pressing and drying, in order to reduce the breakage of the yarn in the process of weaving, about 8666 processing is carried out at 60-7 0 ° C in the absence of 0.3-0.5 g / l of hydroxyethyl alkylphenop with a continuous extraction to a humidity of 50-8O% .5 Sources of information taken into account during the examination 1.
