Abstract

The invention relates to a brocade fabric active and neutral dye combination catalytic fixation printing technique. The technical problem to be solved is to provide a printing technique which can produce a brocade printing clothing plus material with top grade and light mass which is comfortable to wear. The technical proposal is that (1) textile pretreatment, the textile is pretreated by desizing, boiling, and bleaching; (2) presetting, technique conditions are that the temperature is 160 to 165 DEG C and the time is 30 seconds; (3)printing formulation preparation, 40 to 50 % of printing thickener, 0.05 to 1.0% of fixation catalytic agent, 1 to 1.5% of alkaline agent, 1% of reserve salt, 5% of urea, active dye and an amount of neutral dye and rest of water; (4)printing technique, according to the formulation in the step (3), the printing is carried out; the aging temperature is 102 to 105 DEG C, and the aging time is 18 to 20 min; (5) washing and soaping, fixing agent FRC is used forthe after-treatment, afterboarding and tentering of the printing plus material. The technique is suitable for textile printing and dyeing industries.

Description

technical field [0001] The invention relates to a catalytic color-fixing printing process of reactive and neutral dyes in the same slurry, in particular to a catalytic color-fixing printing process of active and neutral dyes in the same slurry for cotton nylon fabrics. It is suitable for the textile printing and dyeing industry, especially for the printing of cotton and nylon interwoven fabrics. The present invention is also applicable to the same paste printing of viscose and nylon fabrics, various hemp and nylon fabrics and the like. Background technique [0002] Natural cellulose fiber has always occupied an important position due to its advantages such as comfortable wearing, abundant resources, and strong availability. Cellulose fiber reactive dye printing is an important development direction of natural fiber printing. Reactive dye printing products are bright in color, soft to the touch, and high-grade. Nylon fabric has the characteristics of high strength, high ela...
