Abstract

The invention discloses a urea-free reactive dye printing method with special mineral soil as a thickener. Mill base is prepared from x% of active dye, 0.5-1.5% of resist salt S, 1-3% of sodium bicarbonate, 60-80% of stock thickener and y% of water, wherein the stock thickener is prepared from, by mass, 48-58% of raw mineral soil and 35-45% of sodium modified mineral soil. The printing process includes the steps of mill base preparing, printing, drying (80 DEG C), steaming (100-102 DEG C, 10 min), water washing (by means of cold running water), soap boiling, water washing and drying, wherein the bath ratio is 1:50, the density of soap flakes is 3 g / L, the density of sodium carbonate is 2 g / L, the temperature of soap boiling is 95 DEG C, and soap boiling time is 10 min. By means of the method, printed fabric has the printing effects of high surface color yield rate, clear pattern outline and soft hand feeling. The method has the remarkable advantages that the special mineral soil thickener replaces a sodium alginate thickener, and cost is reduced; urea-free printing reduces emission of ammonia and nitrogen, and ecological environment protection is easy.

Description

technical field [0001] The invention relates to the technical field of textile printing, in particular to a urea-free reactive dye printing method using special mineral soil as a paste. Background technique [0002] Reactive dyes can be covalently bonded with cellulose fibers, the printed fabrics have high color fastness to washing, and the reactive dyes have bright color, complete color spectrum, and simple printing process, so they are widely used in the printing of cellulose fiber fabrics. [0003] Paste is an important component of printing paste, which plays a decisive role in printing effects such as the surface color yield of printed fabrics, the outline clarity of patterns and the uniformity of color yield on block surfaces. For many years, in the printing of reactive dyes, sodium alginate is the most commonly used paste, because of the evenly distributed carboxyl groups in its macromolecular structure, it can effectively repel the reactive dyes from reacting with th...
