Printing method for polyester fibre/acetate blended high-grade resist printing face fabric

Abstract

The invention relates to the textile printing and dyeing industry. A method for printing a terylene / acetic acid blended high-grade dye-resisting printed fabric, which comprises the following steps: a first step of preparing printing paste: adding dye-resisting agent C into pearlescent pigment printing paste, and adding dye-resisting agent 550 into disperse dye printing paste; a second step of overprinting: carrying out multi-chromatic printing by a flat screen printing machine, drying and cropping; a third step of dyeing a ground color: pad-dyeing the ground color by using the dye-resisting disperse dye prepared in the first step; and a fourth step of post treatment: ageing the fabric dyed with the ground color at a high temperature of between 170 and 190 DEG C, then water washing, and cropping to obtain a product. The method uses differential fiber P / TA blended fabric to develop a new double-component dye resisting printing process, prevents the disperse dye dyed with the ground color from locally dyeing on a printed part, and removing the disperse dye to achieve the aim of fresh color; and proper water washing assistant and water washing temperature overcome the defect of staining of the printed fabric caused by the loose color of the disperse dye. The printed fabric has good printing durability.

Description

Printing method of polyester / acetate blended high-grade resist printing fabric 1. Technical field: The invention relates to a textile printing and dyeing production method, in particular to a printing process for polyester / differential fiber blended fabrics. 2. Background technology: As we all know, Japan, South Korea, and some European countries are world leaders in the application of polyester / new differentiated fibers to develop high-grade textile and apparel fabrics, especially in the high-end printing and dyeing deep processing technology and special printing and dyeing technology. Experience is worth learning from. Although my country's chemical fiber industry started relatively late, the rapid development of my country's synthetic fiber industry in the past decade or so has brought high-speed impetus to the subsequent industrial chain and greatly improved the level of domestic R&D printing and dyeing technology. The new raw material of differentiated fiber (P / TA pr...

AI Technical Summary

Problems solved by technology

The new raw material of differentiated fiber (P / TA printed fabric) is made of polyester filament in the warp direction and 35% polyester staple fiber and 65% triacetate staple fiber blended yarn in the weft direction; Compared with filament fabric, it has excellent drape, soft hand, and cool comfort, so it is widely loved by consumers. However, there are still many deficiencies in the printing process, mainly due to superimposed dyeing to the printed parts. Disperse dyes are difficult to remove, which affects the brightness of the color; floating colors cause staining of printed fabrics during washing, which affects the design and color, and most of the design and color varieties are relatively monotonous
