Production and processing equipment and method for high-glossiness draw-textured yarn

Abstract

The invention provides production and processing equipment and method for high-glossiness draw-textured yarn, and relates to the technical field of spinning. The production and processing equipment for the high-glossiness draw-textured yarn comprises a rack, a mounting plate fixedly connected to the side wall of the rack and a cross beam fixedly connected to the inner side of the rack. According to the production and processing equipment and method for the high-glossiness draw-textured yarn, the refractive index and transmissivity of fiber are ensured through four-leaf spinneret orifices, polymer dissolution caused by nano Ag2O during modification, addition and blending in the later stage can be prevented by using a chemical coprecipitation method, the interfacial effect of solid-liquid reflection is reduced through pulping operation, and the esterification rate in the polymerization process is improved. A pressurized esterification processing technology is adopted, the reaction activity is guaranteed, the reaction rate is increased, air is blown by an air blower to enter an annular blowing channel to cool tows, the air filtered by an air filter box is free of impurities, tow surface pollution is avoided, and meanwhile air pressure is adjusted by an air pressure adjusting box. The problems of many broken filaments and easy end breakage of the tows are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a production and processing equipment and method for high-gloss stretched textured yarn. Background technique [0002] Polyester is an important variety of synthetic fibers. It is the trade name of polyester fiber in my country. It is made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) as raw materials. , the fiber-forming high polymer obtained through esterification or transesterification and polycondensation reaction - polyethylene terephthalate (PET), the fiber made by spinning and post-treatment, the so-called polyester filament, It is a filament with a length of more than one kilometer, and the filament is wound into a group. According to different production methods, polyester filament is generally divided into three categories: primary filament, stretched filament and textured filament. [0003] Stretch textured yarn generally...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a production and processing equipment and method for high-gloss stretch-textured yarn, which solves the problem of polyester stretch deformation produced by traditional high-gloss stretch-textured yarn production and processing equipment and methods. The post-filament processing products are poor in comfort and flexibility, the surface of the tow has poor refraction and reflection effects on light, the gloss is dull, and there are many hairs, which are easy to break, and the woven fabric lacks softness and beauty.
