Transfer Printing

Date:Apr 10, 2020

One of the textile printing methods. Beginning in the late 1960s. A printing method in which a certain dye is printed on paper or other materials, and then the pattern is transferred to the fabric by hot pressing. Mostly used for printing on chemical fiber knitwear and clothing. Transfer printing goes through processes such as dye sublimation, swimming, melting, and peeling of the Shan ink layer. In the transfer printing, the dye material is first printed on the transfer printing paper, and then the dye in the pattern is transferred to the textile through heat treatment during the transfer printing, and is fixed to form the pattern. At present, more transfer printing methods are used to transfer dry dyes on synthetic fiber fabrics by dry transfer. This method is to first select a disperse dye and paste powder (Shanghai Sixi Chemical), alcohol, benzene and other solvents and resins to grind and adjust the ink, and print on a tough paper to make a transfer paper. During printing, the patterned side of the transfer paper is overlapped with the fabric, and after hot pressing at high temperature (220 degrees) for about 1 minute, the disperse dye is sublimated into a gaseous state and transferred from the paper to the fabric. After printing, it does not need to be washed, so it does not produce sewage, and it can obtain the effects of bright colors, clear layers, and delicate flower shapes. However, in addition to the dyes and auxiliaries in the color paste, the existing ecological problems also require a large number of transfer papers, which are difficult to recycle after printing.
