A kind of printing and dyeing method of cotton fiber for infants and young children

Abstract

The invention belongs to the technical field of textile printing and dyeing, and discloses a printing and dyeing method for cotton fibers for infants and young children. ) dyeing: carry out dyeing treatment with natural dyeing agent; (3) vacuum pressing: carry out vacuum pressing treatment to the cotton fiber after dyeing; (4) color fixing: carry out color fixing treatment to cotton fiber after vacuum pressing treatment; (5) Impregnation modification: Impregnation and modification of the fixed cotton fibers are carried out with collagen-simulated body fluid composite impregnation solution, and then rinsed and dried. The cotton fiber printing and dyeing method of the invention can not only maintain the strength of the cotton fiber, improve the durability and comfort of the fabric, but also make the cotton fiber have high dyeing fastness, thereby effectively improving the dyeing and wearing performance of the cotton fiber for infants and young children.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a printing and dyeing method of cotton fibers for infants and young children. Background technique [0002] Cotton fiber has good moisture absorption, air permeability, softness, hygiene and wearing comfort, and is welcomed by consumers. In order to achieve the purpose of aesthetics and other uses, it is often necessary to print and dye cotton fibers before they are made into cotton textiles. Infant textiles mainly include outerwear, underwear, towels, etc. Since infants and young children have relatively weak resistance and delicate skin, they are more sensitive to external stimuli, so they have special requirements for the textiles used. The currently commonly used cotton fiber printing and dyeing method usually requires scouring the cotton fiber before printing and dyeing to remove impurities such as pectin, wax and protein in the cotton fiber, which reduc...

AI Technical Summary

Problems solved by technology

The commonly used cotton fiber printing and dyeing method usually needs to scouring the cotton fiber before printing and dyeing to remove impurities such as pectin wax and protein in the cotton fiber, which reduces the strength of the cotton fiber and affects the performance of cotton textiles. There is also the common problem of poor color fastness and easy fading. Because infants are used to licking and sucking items, once the dye is ingested into the body by mouth, it will have adverse effects on infants.
