Embodiment 1

[0015] A chlorine-free shrink-proof finishing process for wool tops, including the following steps:

[0016] 1) Washing: Wash the wool top with water to remove impurities in the wool top;

[0017] 2) Biological enzyme anti-shrink treatment: immerse the washed wool sliver in a bio-enzyme anti-shrink treatment solution at a temperature of 60℃ for padding treatment, wherein the dipping bath ratio is 1:10 and the liquid pressure ratio is 95% ,

[0018] The bio-enzyme anti-shrink treatment solution includes the following components in mass percentages: hydrogen peroxide 1%, sodium bisulfite 5%, composite protease B 18%, silicone resin 38%, penetrant 9%, acrylic resin 29%;

[0019] 3) Drying: Dry the wool tops that have undergone bio-enzyme shrink-proof treatment to obtain finished wool tops with shrink-proof and anti-pilling properties.

Abstract

The invention discloses a chlorine-free and shrink-proof finishing technology of wool tops. The chlorine-free and shrink-proof finishing technology comprises the following steps: 1) washing with water: carrying out water-washing pre-treatment on the wool tops to remove impurities in the wool tops; 2) carrying out biological enzyme shrink-proof treatment: immersing the wool tops subjected to the water-washing treatment into a biological enzyme shrink-proof treatment solution; carrying out padding treatment, wherein the biological enzyme shrink-proof treatment solution is prepared from the following components in percentage by mass: 1 percent to 3 percent of hydrogen peroxide, 2 percent to 5 percent of sodium hydrogen sulfite, 15 percent to 20 percent of compound proteinase B, 35 percent to 40 percent of organic silicone resin, 7 percent to 10 percent of a penetrating agent and 29 percent to 33 percent of acrylic resin; 3) drying: drying the wool tops subjected to the biological enzyme shrink-proof treatment to obtain a wool top finished product with shrink-proof and anti-pilling performance. By adopting the manner, a technological flow is shortened so that the treated wool tops reach machine-washable shrink-proof effect of traditional chlorination and the anti-pilling performance is improved; in a finishing process, AOX (Absorbable Organic Halogen) pollution is not generated, and energy saving and environmental friendliness are realized.

Description

Technical field [0001] The invention relates to the technical field of wool top processing, in particular to a chlorine-free shrink-proof finishing process for wool tops. Background technique [0002] The surface of the wool fiber has a scale layer with a special structure. Under the friction of external force, the scale layer produces directional movement and felt shrinkage. Therefore, the wool fiber strip must be finished and processed to meet the machine washable standard specified by the International Wool Bureau. At the same time, the finishing process can improve the feel and comfort of wool fiber strips. [0003] For a long time, most companies have used chlorine-containing oxidants to finish the wool fiber strips to achieve a good anti-felting effect. However, the chlorine-containing oxidants will produce a large amount of AOX (adsorbable organic Halides) seriously pollute the environment and cause harm to the human body. At the same time, the process is complicated, the o...
