Aug 01, 2018

It started in the late 1960s.A method of printing in which a dye is printed on paper or other materials and then heat pressed to transfer the pattern to the fabric.Used for printing of chemical fiber knitwear and garments.Transfer printing through dye sublimation, swimming, melting, shantou - ink layer stripping process.

Transfer printing is to print the dye material on transfer printing paper first, and then transfer the dye from the pattern to the textile by heat treatment during transfer printing, and fix it to form the pattern.The most commonly used transfer printing method is to use disperse dyes on synthetic fiber fabrics by dry transfer.This method is to select the combination of disperse dyes and paste powder (Shanghai sixi chemical industry), alcohol, benzene and other solvents and resin grinded into ink, printed on tough paper to make transfer paper.When printing, the patterned side of the transfer paper is overlapped with the fabric. After hot pressing for about 1min at high temperature (220 degrees), the disperse dyes sublimate into gas and transfer from the paper to the fabric.After printing does not need to wash treatment, so does not produce sewage, can obtain the color bright, the level clear, the flower shape delicate effect.However, in addition to the dyes and auxiliaries in the pulp, a large number of transfer paper is needed, which is difficult to be recycled after printing.
