Disperse dye digital printing technology

Abstract

The invention relates to a disperse dye digital printing technology. The disperse dye digital printing technology comprises the following steps that 1, fabric is divided into polyester fabric and non-polyester fabric, wherein the polyester fabric comprises blended fabric taking polyester as the main material, and the non-polyester fabric needs to be subjected to pretreatment to obtain the pretreated non-polyester fabric; 2, disperse dye ink or printing ink for printing is prepared, and the color base is a printing colorant formed by blending the disperse dye; 3, color ink obtained in the second step is printed on transfer paper, namely stained paper through a printing or digital printing method; 4, the front face of the stained paper in the third step is tightly attached to the printed fabric, wherein the printed fabric is the polyester fabric or the pretreated non-polyester fabric; 5, the disperse dye in the color ink sublimates through high temperature pressing to be adsorbed on the surface of the fabric, fixation is conducted on fiber, and patterns with corresponding colors are displayed. The disperse dye digital printing technology has the advantages of being simple in equipment, small in investment, short in technological process, environmentally friendly, good in quality, high in flexibility and the like.

Description

technical field [0001] The invention relates to a disperse dye digital printing process. Background technique [0002] Digital printing technology is a high-tech product that integrates machinery, computer, electronic information technology and gradually formed with the continuous development of computer technology. Its advanced production principles and methods have brought an unprecedented development opportunity to the textile printing and dyeing industry. . In recent years, my country's textile printing and dyeing industry has developed rapidly, and printing output has also increased simultaneously. At the same time, the fashion cycle of clothing is getting shorter and shorter, patterns are changing faster and faster, and production requirements are getting higher and higher. Digital printing is to directly print various special dyes (reactive, disperse, acid and paint) onto various fabrics or other media through various digital means, and then after processing, variou...

Problems solved by technology

[0007] The process of textile digital printing varies with the dyes and fiber types used, but digital printing also has its limitations and shortcomings. The post-treatment of dye digital printing (such as acidic, reactive) still cannot get rid of washing and discharge sewage, and the fabric types are relatively single. , limited to simple fibers
