Dyeing Process of Mercerized Cotton Yarn

Abstract

The invention discloses a mercerized cotton yarn dyeing process. According to the technical scheme, the mercerized cotton yarn dyeing process comprises the following steps: performing singeing on mercerized cotton yarns, and removing villi formed by fibers on the surfaces of the mercerized cotton yarns; processing raw yarns into skein yarns by using a skein machine; soaking and rolling the skein yarns with an alkali liquid, performing mercerization treatment so as to obtain good gloss, and cleaning the surfaces of the skein yarns; adding neutralization aids and an alkali liquid for treating the surfaces of the skein yarns; adding water, active dyes and aids, heating to 60 DEG C, keeping the temperature, performing yarn dyeing, and cleaning for multiple times later; adding a softening agentand water, heating to 40 DEG C, keeping the temperature, dewatering and drying, turning over the yarns, finally forming yarn barrels, and packaging and storing in warehouses. The process has the effects that processing procedures are shortened and water resources can be saved.

Description

technical field [0001] The invention belongs to the technical field of fabric printing and dyeing, and more specifically relates to a mercerized cotton yarn dyeing process. Background technique [0002] Mercerized cotton yarn is made of cotton, which is worsted to make high-weaving yarn, and then mercerized to make a smooth, bright, soft and wrinkle-resistant high-quality mercerized yarn. [0003] The Chinese patent with the current notification number CN101892569B discloses a process for mercerizing dyeing of loose fibers, including mercerizing dyeing of loose fibers, finishing and dehydration drying, wherein mercerizing dyeing of loose fibers is first mercerized and then dyed, and both mercerizing and dyeing are carried out Finished in the dyeing vat, and the mercerizing process does not add tension, the mercerizing dyeing includes the following steps: put the loose fiber in water with a bath ratio of 1:6-10 at room temperature, add mercerizing additives, the dosage is 80-...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, similar to the above-mentioned loose fiber mercerizing dyeing process, the loose fiber without the loosening process is directly dyed. Since the loose fiber is fluffy and disorderly piled up, it needs to be neutralized and washed many times for uniform dyeing, prolonging the dyeing process, resulting in waste of water
