AI Technical Summary

Problems solved by technology

[0003] At present, when the webbing is continuously tie-dyeed in dark colors, especially black, the shrinkage of the edge tape is large. After the customer makes the clothes and washes them, the clothes will be deformed due to the large shrinkage, which will bring losses to the customers.
[0004] When making black edging tape, due to the limitation of the machine and the influence of the color fixing agent, when the dyeing machine is dyeing dark colors, the tension regulator should be adjusted tightly (if it is too loose, it is easy to stop and cause color flowers ), the shrinkage rate of the dyed webbing reaches 11% when the adjustment is tight, and it improves after relaxation, but it is still 8-9%, which still cannot meet the customer's requirements

Abstract

A disclosed processing technology for improving dyeing shrinkage rate of a multi-composition core-spun yarn comprises the following steps: yarn matching, dyeing, processing in a steam box, normal-temperature water washing, first water washing, second water washing, third water washing, forth water washing, fifth water washing, sixth water washing, cold water washing, processing in a slurry groove, processing in a flat tube, and discharging of fabric tapes. A prepared fabric tape has the shrinkage of 5th-6th grade and the dye-penetrating degree of 4th grade or more.

Description

technical field [0001] The invention specifically relates to a processing technology for improving the shrinkage rate of the multi-component core-spun yarn during dyeing. Background technique [0002] Cotton, bamboo pulp fiber, and bamboo charcoal fiber can all meet the product's requirements for moisture absorption, breathability and comfort. The good luster and low modulus of bamboo pulp fiber can improve the luster and drape of cotton fiber, and its hygroscopic and quick-drying properties can improve the moisture release performance of cotton fiber. And cotton fiber can also make up for the shortcoming of insufficient wet strength of bamboo pulp fiber. At the same time, bamboo pulp fiber and bamboo charcoal fiber have high dry strength and good wear resistance, and their products have antibacterial, deodorant functions and strong anti-ultraviolet performance. The heat resistance of DOWXLA fiber is greater than 220°C, it has strong stability to most strong corrosive chem...
