The production process of cvc burning cotton, dispersing and co-printing and co-printing with paint color paste

Abstract

The invention discloses a production process of CVC co-printing by one paste for burnout pirnting and disperse dye pirnting with a pigment printing paste. The invention quantifies the auxiliary components in the one paste for burnout pirnting and disperse dye pirnting and process parameters, and employs a unique washing water technology. Specifically, a formula of the one paste for burnout pirnting and disperse dye pirnting is as below: 10%-14% of sodium bisulfate, 1%-6% of a disperse dye, 3%-5% of glycerin, 3%-5% of mineral oil and the balance of an original paste. A formula of the pigment printing paste is as below: 1%-6% of a high temperature coating, 10%-25% of an imitating reactive solid slurry, 1%-3% of a thickening agent and the balance of soft water. The process is as below: after printing, baking at the temperature of 150 DEG C for 2-3 min, conducting high temperature steaming at 170 DEG C for 5-6 min; and conducting water washing process mainly by boiling a disperse agent at 70 DEG C for 15 min twice. The invention overcomes inconsistent points of conditions of the burnout pirnting and the disperse printing, bright color can also be printed on the burnout printing sites, and the disperse dye and pigment can show good dry and wet fastness performance. The process provided by the invention is stable and easy, and can be used for mass production by machine; and the product has various colors, strong stereo feeling of patterns and high contrast.

Description

technical field [0001] The invention relates to a production process of CVC burning cotton, dispersing and co-printing with paint color paste. Background technique [0002] Burnout printing (burnout printing) is a fabric composed of two fibers, one of which can be destroyed by a certain chemical, while the other is not affected; therefore, a chemical can be adjusted into a printing paste for printing Later, after proper post-treatment, one of the fibers is destroyed to form a burnt-out printed fabric with a special style and transparent style. This kind of pattern is either concave and convex in order, or translucent, and has a strong decorative effect. Appropriate resistant dyes can also be added to the printing paste to color another fiber component while rotting one fiber component to obtain a colored burn-out effect. The burnt-out printing of common polyester-cotton blended fabrics is also called burned-cotton printing. [0003] Burnt-out printed fabrics in my country...

AI Technical Summary

Problems solved by technology

Burning cotton drying is more sensitive to the baking temperature, too high or too low temperature will affect the burning effect, too high temperature will cause the polyester fiber after burning to turn yellow; too low temperature will cause insufficient carbonization of cotton fiber and affect Burnt flower effect, increased washing difficulty, disperse dyes are usually steamed at 170°C for 8 minutes at normal pressure, and their fastness and color can be guaranteed. Moreover, many dispersants are not resistant to burning cotton pulp, and there will be burning cotton dispersion. Uneven printing color and other defects

Therefore, the printing process of burning cotton and dispersing the same paste is only a small-scale printing and has not been developed.
