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.

Embodiment 1～12

[0016] 1. Preparation of finishing agent: Add the required amount of alkylsulfonate and sodium bicarbonate into a certain amount of water, heat the water to about 40°C, and stir to form a uniform solution.

[0017] 2. Anti-pilling treatment of fabrics: immerse the selected fabric containing acrylic fibers in the above-mentioned finishing agent. The fabric needs component A 0.04~2.8g. 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.

[0018] Pilling performance was measured on the same treated and untreated fabrics.

[0019] The composition of the finishing agent prepared in each embodiment and the fiber composition of the test fabric are shown in Table 1, and the comparison results of the pilling performance...

Abstract

This invention relates to a finishing agent used for declining acrylic fibre balling up property, which comprises a water solution including compound A and compound B, wherein the A content is 0.05-3.50wt%, B content is 0.1-6.0wt%, the A is alkyl sulfonate of the C8-C18, B is baking soda. When using, soaking the acrylic fibre or the textile including acrylic fibre into the agent, then drying the textile with a certain agent water in 60-120 Deg. C. The valid component of the agent is innocuous to the human, and has no objectionable odor; besides, it is effective to against balling up of the acrylic fibre.

Description

technical field [0001] The invention relates to a finishing agent for reducing the pilling performance of acrylic fibers, and the finishing agent contains alkyl sulfonate. 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, yarn structure, fiber linear density, and fiber cut length, etc. These are the important reasons for its easy pilling.
