Printing and dyeing auxiliaries for wool and cashmere

Abstract

The invention provides printing and dyeing auxiliaries for wool and cashmere. The printing and dyeing auxiliaries comprise, by weight, 2-4 part of ethylene glycol, 3-4 parts of amino-silicone oil, 40-52 parts of deionized water, 10-12 parts of benzyl sodium naphthalene sulfonate, 6-7 parts of high-permeability agent OP-6, 10-11 parts of citric acid, 3-5 parts of methyl siloxane, 6-7 parts of sodium diethylhexyl sulfosuccinate and 8-10 parts of ethylene oxide. Compared with the prior art, the printing and dyeing auxiliaries have the advantages that the citric acid and the amino-silicone oil are combined, the dyeing effect and fixation effect of dye on wool and cashmere products can be increased, color fastness is increased, color improving and protection performance can be increased, the dyeing effect can be guaranteed, dust and impurities on the surface of wool can be removed favorably, and wool yarn spun by the processed wool is good in softness, excellent in anti-pilling performance and the like.

Description

technical field [0001] The invention relates to a printing and dyeing auxiliary for wool and cashmere, which belongs to the field of wool products production auxiliary. Background technique [0002] The preparation process of wool and cashmere involves printing and dyeing processes, and when fabrics with poor color fastness encounter water, sweat, sun, saliva or physical friction, the dyes are easy to fall off and fade, which affects the appearance, and the fallen dye molecules or heavy metals Ions may be absorbed by the body through the skin and pose a health hazard. Therefore, auxiliaries are often used in the printing and dyeing process to improve the dyeing effect and increase the color fastness. Printing and dyeing auxiliaries include printing auxiliaries and dyeing auxiliaries. Printing auxiliaries include thickeners, adhesives, cross-linking agents, emulsifiers and other printing auxiliaries. Dyeing auxiliaries include dyeing agents, leveling agent etc. Although th...
