Problems solved by technology

[0008] Although the process of pigment dyeing and printing paste is simple, most of the dyeing agents use formaldehyde-containing carving white powder or decolin and non-environmentally friendly auxiliaries. The dyeing aid is removed from the fabric, which not only cannot be guaranteed to be exhausted, but also requires a lot of water

Abstract

The invention discloses an environment-friendly discharge printing technology which comprises the specific steps of: performing pre-treatment on knitted cloth; then performing rotary screen printing; and finally adopting one of high-temperature roasting and high-temperature steaming. Printing paste used for the environment-friendly discharge printing technology comprises components in percentages by weight as follows: 10-20% of leucotrope, 12-50% of a solvent, 20-30% of a paste material and the balance water. The printing paste disclosed by the invention does not contain odor from free formaldehyde and free sulfur, so that the environment-friendly discharge printing technology which uses the printing paste does not need water-washing and soap-washing. Thus, the environment-friendly disperse dye printing technology is not only environment-friendly, but also saves plenty of water and energy, and is in accordance with a principle of low carbon economy.

Description

Technical field: [0001] The invention relates to a knitting printing process and the printing paste used therein, in particular to an environment-friendly dyeing printing process and the printing paste used therein. Background technique: [0002] Displacement dyeing printing is one of the three printing methods of fabrics (direct printing, dial dyeing printing and resist printing). Traditional dial dyeing printing is mainly for woven fabrics. The background color area is large, and the color is deep and bright, with a unique style. It is difficult to use direct printing to achieve the effect of fine patterns, so dial dyeing printing is required. [0003] The earliest dial-dyeing printing (in the 1950s) was cotton twill fabric, which printed dragon and phoenix patterns on the background colors of red, maroon and navy blue. The most important is vat dyes (printing paste) and insoluble azo dyes (background color). The dyeing paste is mainly made of white powder, caustic soda a...
