Problems solved by technology

[0002] Wool fabric is a kind of natural fiber fabric. Wool fiber has excellent performance, excellent curl and elasticity, warm and comfortable, and is deeply loved by consumers. However, wool fabric has insufficient bright colors, poor wet fastness and felting shrinkage. The biggest problem, this is because the wool surface has a tight scale layer, and the outermost layer of wool scales contains a thin hydrophobic layer, which affects the wettability of the wool surface and hinders the adsorption and diffusion of dyes, thus affecting the dye. In addition, its fiber characteristics are easy to feel and shrink, which also brings difficulties to uniform dyeing and printing.

Embodiment 1

[0023] A shrink-proof printing process for wool fabrics, comprising the following steps:

[0024] (1) Ultrasonic cooking pre-treatment: put the woolen fabric in distilled water at 100°C, and perform alternating ultrasonic treatment with high, medium and low frequency ultrasonic waves, first with medium frequency ultrasonic for 3 minutes, then with low frequency ultrasonic for 6 minutes, then with medium frequency ultrasonic for 3 minutes, and then After 2 minutes of high-frequency ultrasonication, the decocting treatment is completed, and after the natural cooling to room temperature, ultrasonic cleaning is performed, and biological enzymes and neutral detergents are added. The amount of biological enzymes is 2g / L, the amount of neutral detergent is 15g / L, and the pH is adjusted to 5.0, low-frequency ultrasound for 8 minutes; wherein, the frequency of low-frequency ultrasound is 25Hz; the frequency of high-frequency ultrasound is 130Hz; the frequency of medium-frequency ultraso...

Abstract

The invention discloses a shrink-proof printing process for wool fabrics. The process includes steps of ultrasonic crabbing pretreatment, alkali shrinkage pretreatment, printing pretreatment, printing, steaming for fixation, after finishing, washing and drying. Before printing, ultrasonic crabbing pretreatment and alkali shrinkage pretreatment are performed, felting of the wool fabrics is improved, and on the other hand, color fastness in printing of cotton and linen fiber fabrics is effectively improved; chlorine is adopted in alkali shrinkage pretreatment to further prevent felting; in addition, a specially-made double-dye printing paste is adopted for printing to further increase the dye sorption rate. The shrink-proof printing process for the wool fabrics has advantages of smoothness in printing, bright color, proper coloring depth, high color fastness to rubbing after printing, wet fastness improvement, felting reduction and the like.

technical field [0001] The invention relates to a fabric processing method, in particular to a shrink-proof printing process for wool fabrics. Background technique [0002] Wool fabric is a kind of natural fiber fabric. Wool fiber has excellent performance, excellent curl and elasticity, warm and comfortable, and is loved by consumers. However, wool fabric has insufficient bright colors, poor wet fastness and felting shrinkage. The biggest problem, this is because the wool surface has a tight scale layer, and the outermost layer of wool scales contains a very thin hydrophobic layer, which affects the wettability of the wool surface and hinders the adsorption and diffusion of dyes, thus affecting the dye. In addition, its fiber characteristics are easy to feel and shrink, which also brings difficulties to uniform dyeing and printing. [0003] Therefore, a new technology is needed to solve the above problems. Contents of the invention [0004] Purpose of the invention: In ...
