Wrapping system of chinlon hemp grey yarn and preparing technology of chinlon hemp grey yarn

Abstract

The invention discloses a wrapping system of chinlon hemp grey yarn and a preparing technology of the chinlon hemp grey yarn. The chinlon hemp grey yarn are woven from chinlon yarn and polyester yarn. The wrapping system comprises a yarn feeding mechanism, a preprocessing mechanism, a covering yarn drafting mechanism and a coiling mechanism. The yarn feeding mechanism comprises two yarn bobbins for containing the chinlon yarn and the polyester yarn and a yarn feeding roller, and the yarn on the yarn bobbins is driven by the yarn feeding roller to enter the wrapping system. The preprocessing mechanism comprises a heating box and a cooling plate, wherein the heating box is a transformable heating box and is used for conducting heating and plasticizing on the yarn, and the cooling plate is used for fixing a curled structure after the yarn is twisted. The covering yarn drafting mechanism comprises a false twister, a second roller, a yarn stitching machine and a third roller. Drafting force is produced by the second roller and the yarn feeding roller and by the second roller and the third roller. An auxiliary roller is arranged between the yarn stitching machine and the third roller. By means of an existing elasticizer structure, a yarn path is lengthened to be about 5 m, and the tension of the yarn and the overall tension uniformity are effectively adjusted.

Description

technical field [0001] The invention relates to the field of chemical fiber coated yarns, in particular to a coating system of nylon hemp yarn and a preparation process thereof. Background technique [0002] Color spun yarn is colored yarn that is dyed first and then spun; colored yarn is colored yarn made by scouring and dyeing natural colored yarn. Nylon is the Chinese name of synthetic fiber nylon, and the translated name is also called "Nylon". , "Nylon", the scientific name is polyamidefibre, that is, polyamide fiber. Polyester is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions. - Polyethylene terephthalate (PET), fibers made by spinning and post-processing. Yarns made of black polyester and white polyester blends are collectively called hemp gray yarns. [0003] At present, hemp yarn is generally woven by wrapping m...

AI Technical Summary

Problems solved by technology

[0003] At present, hemp ash yarn is generally woven by wrapping machine / covered yarn machine, and the yarn is covered through the bobbin and the spindle that drives the bobbin to rotate. This structure has a short silk path (about 2m), and the tension of the weaving hemp ash yarn The uniformity is poor. For the hemp gray series yarns with high color fastness requirements, it is easy to cause different patterns / types (different depth and light lines) and graining (horizontal stripes)
