Problems solved by technology

However, the obvious defect of these finishing agents is that the selection of their effective components is not ideal. Among them, aniline, aniline hydrochloride, aniline acetate, and aniline sulfate are harmful compounds to the human body, and the acrylic fiber produced is easy to change color. , N, N-dimethoxydihydroxyethylene urea has a strong odor, and the fibers and fabrics treated with it will be harmful to health if they are in contact with the human body for a long time, or they will bring discomfort to the contactor.

[0017] 1. Preparation of finishing agent

[0018] Add the required amount of alkyl sulfonate and sodium bicarbonate into a certain amount of water, heat the water to about 40°C, and stir to form a uniform solution.

[0019] 2. Anti-pilling treatment of fabrics

[0020] Immerse the selected fabric containing acrylic fiber in the above-mentioned finishing agent, the amount of finishing agent is based on component A, and the dry weight of acrylic fiber or fabric containing acrylic fiber requires 0.04-2.8 components g. The finishing agent is heated to 50-80°C in advance, and its temperature is kept within this range, and the soaking time is 10 minutes. After the treatment is completed, the liquid content of the sample fabric is controlled at 60-120% by means of squeezing liquid, and then the fabric is dried at a temperature of 80°C.

[0021] Pilling performance was measured on the same treated and untreated fabrics.

[0022] The composition of the finishing agent prepared in e...

Abstract

This invention relates to a method for decreasing acrylic fiber balling up property, which comprises the following steps: a) soaking the acrylic fiber or textile contenting acrylic fiber into the finishing agent 5-60 minutes in 50-80 Deg.C; b) drying the fiber or textile with the liquid content 60-120% in 60-120 Deg.C. The finishing agent is the water solution of compound A and compound B, wherein the content of A is 0.05-3.50wt%, B: 0.1- 6.0wt%, A is the alkyl sulfonate of C8-C18, B is baking soda; it needs A 0.04-2.8g per 100g acrylic fiber or textile.

Description

technical field [0001] The invention relates to a method for reducing the pilling performance of the acrylic fiber, in particular to a method for reducing the pilling performance of the acrylic fiber by dipping the acrylic fiber or a fabric containing the acrylic fiber with a finishing agent. Background technique [0002] Acrylic fiber accounts for a large proportion of synthetic fibers, its characteristics are close to wool, soft, fluffy and warm, and has excellent light resistance and radiation resistance. It is ideal for making underwear, fabrics, sweaters, blankets and Ideal raw material for fabrics such as carpets. However, fabrics containing acrylic fibers, especially knitted fabrics, are prone to pilling after being subjected to frequent friction, which not only affects the appearance of the fabric, but also causes poor styles such as hand feel. It is generally believed that the occurrence of this pilling phenomenon is related to factors such as fabric structure, yar...
