Polyamide filament elastic yarn processing process applicable to sizing of short fiber sizing machine

Abstract

A polyamide filament elastic yarn processing process applicable to sizing of a short fiber sizing machine relates to the technical field of weaving polyamide filament elastic yarn sizing. The process comprises performing a warping step through the creel of a small V-type column tensioner arranged on a warping machine, wherein the weight of the tension bars of the tensioner is 2.6 g, and the single yarn tension of the tension bars of the tensioner is 9 g; performing a sizing step through the short fiber sizing machine, during which applied sizing agent contains low-polymerization degree PVA (polyvinyl alcohol) and polyacrylate adhesives, the sizing temperature is 50-60 DEG C, and yarns in every area are straight and flat without twisting. The polyamide filament elastic yarn processing process applicable to sizing of the short fiber sizing machine facilitates sizing of the polyamide filament elastic yarns through the short fiber sizing machine, effectively avoids yarn scraping and breakage and further ensures subsequent normal production of polyamide filament elastic fabric.

Description

technical field [0001] The invention relates to the technical field of sizing nylon filament elastic yarn for weaving. Background technique [0002] In the weaving and weaving process, the varieties currently produced on the spun sizing machine are spun yarns with a fiber length of less than 58mm, while the production of such varieties as nylon filament elastic yarn requires a special sizing machine for filaments. The existing spun sizing machine has a long process route, insufficient smoothness of the cylinder drying cylinder, and many guide rollers. When producing nylon filament elastic yarn, it is easy to scrape and break the yarn when it is produced, and it cannot be produced normally. [0003] If a special sizing machine for filaments is used to sizing nylon filament elastic yarn, the following problems exist: [0004] 1. If the sizing rate is too high, not only the surface size film of the silk is too thick, it is easy to cause sizing, but also the sizing silk is hair...

AI Technical Summary

Problems solved by technology

[0004] 1. If the sizing rate is too high, not only the surface size film of the silk is too thick, it is easy to cause sizing, but also the sizing silk is hairy and difficult to weave;

[0005] 2. If the moisture regain is not well controlled during sizing, it is easy to cause sticking, which makes weaving difficult;

[0006] 3. After sizing and drying, it is easy to generate static electricity, and nylon filaments are easy to break
