Problems solved by technology

However, chlorine-containing oxidants will produce a large amount of AOX (adsorbable organic halides) during the finishing process of sweaters, which will seriously pollute the environment and cause harm to the human body; the process is relatively complicated, the operation process is long, and the energy consumption is large. Can cause severe yellowing of wool textiles

Embodiment 1

[0029] An anti-pilling finishing process for wool fabrics, comprising steps:

[0030] (1) Pre-treatment: use combed yarn to weave wool fabric, wash and dry the wool fabric before treatment;

[0031] (2) Enzyme finishing: immerse the pre-treated wool fabric in the finishing solution. The order of immersion in the finishing solution is as follows: the first step: immerse in hydrogen peroxide with a concentration of 40ml / L and a temperature of 50°C for 40 minutes; the second step : immerse the wool fabric soaked in hydrogen peroxide in a solution containing chitosan 2g / L for 1.5h, and the temperature of the solution is 40°C; the third step: immerse the wool fabric soaked in chitosan solution in a solution containing 3% protease (owf ) solution, the bath ratio: 1:30, the solution temperature is 60°C, and the immersion time is 38min;

[0032] (3) Milling: put the wool fabric through enzyme finishing into the milling finishing solution of the ultrasonic cleaner, turn on the ultraso...

Abstract

The invention discloses an anti-pilling finishing process for wool fabrics, comprising the steps of: pretreatment; enzyme finishing; shrinking; scaling and anti-pilling one-bath method; cleaning; drying; padding; The fabric is dried, calendered and shaped. In the present invention, by adding an enzyme finishing process before the milling process, the disulfide bond of the oxidizing agent is converted into a sulfonic acid group, which destroys the continuous distribution of the lipid layer on the surface of the wool fiber, increases the hydrophilicity of the wool fiber surface, and then treats it with protease. It can further increase the removal effect of wool surface scales, and ensure the effect of the subsequent one-bath scaling and anti-wrinkle process.

Description

technical field [0001] The invention relates to an anti-pilling finishing process for fabrics, in particular to an anti-pilling finishing process for wool fabrics. Background technique [0002] Wool textiles are deeply loved by consumers for their good thermal performance, softness, fluffy and fullness. However, there is a scale layer with a special structure on the surface of the wool fiber. In daily clothing, due to the friction of external force, the scale layer will move directionally, and the phenomenon of felt shrinkage will occur, which will cause itching to the human body. Therefore, wool fabrics must be finished to meet the machine-washable standards stipulated by the International Wool Bureau. At the same time, finishing can greatly improve the feel of wool textiles (such as softness, smoothness, etc.), thereby improving their wearing performance and product added value. . For a long time, domestic sweater finishing enterprises have mostly used chlorine-containi...
