Abstract

The invention provides a wetting transfer printing process of a polyester-cotton blended fabric and relates to the field of printing and dyeing. The wetting transfer printing process comprises the following steps: coating printing paper with a modifier, coating the printing paper with a separation agent, preparing transfer printing paper, carrying out transfer printing and press-rolling and carrying out color fixation to obtain a finished product. According to the wetting transfer printing process, the printing paper is modified and the strength, the smoothness and the moisture absorption property of the printing paper are greatly improved; in a subsequent transfer printing process, a transfer printing pattern has a vivid pattern, a fine figure, a clear layer and a strong stereoscopic impression; the separation agent can be used for reducing the adsorption effect of printing paper fibers on dyestuff and improving the printing coloring rate of the dyestuff and can also be used for improving the time of transfer-printing a figure pattern to the fabric; a common universal fabric alkali liquid padding procedure is replaced with a procedure of spraying alkali liquid to the fabric, so that the dosage of the alkali liquid is greatly reduced and the production cost and environment protection pressure are reduced; in a transfer printing process, transfer printing parameters are controlled and the fabric has high apparent color yield and color fastness; the brute force is also reduced in an acceptable range.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to a wet transfer printing process of polyester-cotton blended fabrics. Background technique [0002] Printing and dyeing is a major technical link in the fabric processing industry chain, which determines the final quality and market value of textiles. At present, fine control has not been achieved in the production process of printing and dyeing technology, the utilization rate of dyestuffs is low, and the amount of sewage discharge is large. In the production of circular flat screen printing, each ton of fabric consumes about 200 tons of water, and its water is only used as a reaction medium. Therefore, due to its extensive production process, it will eventually carry a large amount of waste liquid and dyes into sewage and waste water. The economic benefits and environmental protection of printing and dyeing production Protection contradictions are becoming increasingly promine...
