Milk protein fiber/cotton fiber interwoven fabric wet transfer printing method

Abstract

Provided is a wet transfer printing method for an interwoven fabric of milk protein fiber / cotton fiber, comprising steps as follows: 1, preparing a printed thin film; 2, obtaining a wet interwoven fabric of milk protein fiber / cotton fiber; 3, bonding the wet interwoven fabric of milk protein fiber / cotton fiber and the printed thin film together, and entering the resultant into a transfer printing device to perform roll compaction, so as to clearly transfer patterns from the printed thin film to the surface of the interwoven fabric of milk protein fiber / cotton fiber; 4, introducing into a continuous steamer to perform steaming and color development, and performing conventional washing and drying after leaving the steamer. The wet transfer printing of the interwoven fabric of milk protein fiber / cotton fiber can be realized by selecting an appropriate color paste and pretreatment liquid. The pattern designs show fine workmanship, the printed patterns are clear and natural, and the fastness can reach level 3-4 or higher; moreover, the layering of the pattern designs is strong, the white ground part of the pattern designs is pure white and non-yellowing, such that the wet transfer printing can be comparable with the digital direct-jet printing.

Description

technical field [0001] The invention belongs to the technical field of textile printing, and in particular relates to a method for wet transfer printing of milk protein fiber / cotton fiber interwoven fabrics. Background technique [0002] Milk protein fiber uses cow's milk as the basic raw material, first undergoes dehydration, deoiling, degreasing, separation, and purification to become a kind of milk casein with a linear macromolecular structure; then it is blended, crosslinked, and grafted with polyacrylonitrile. It is made into spinning stock solution; finally, it is formed by wet spinning into fibers, solidified, drawn, dried, crimped, shaped, and cut into short fibers. It is a new type of animal protein fiber, which has the advantages of softness, skin-friendliness, breathability, and good moisture conductivity. It is suitable for making high-end underwear, home clothing, etc. [0003] The dyeing process of milk protein fiber is relatively mature, and many companies an...

Problems solved by technology

[0003] The dyeing process of milk protein fiber is relatively mature, and many companies and technicians have conducted research, but there are few reports on its printing process

The main reason is that the milk protein fiber is not resistant to high temperature, and it is easy to turn yellow and hard under high temperature and alkaline conditions, which seriously affects the wearability of the milk protein fiber fabric.
