Problems solved by technology

Regardless of the method, pretreatment or pretreatment process is required, the process is complex, the process is long, and chlorination is polluted
[0014] 2. The treatment effect is not ideal, and it cannot solve the contradiction between refinement and strong maintenance
Treating wool with protease can remove the scales on the surface of the fiber, thereby reducing the diameter of the fiber (the fiber fineness can be reduced by about 2 μm), and improving the fineness of the wool. Serious, it is not conducive to the subsequent textile processing, and has a great impact on the practical performance of the final wool product
Therefore, this reduction treatment is not an ideal method of wool thinning

Abstract

The invention discloses a wool refining treating fluid and a treating method. The treating fluid comprises the following components by weight percent: 0.1-10% of protease, 0.1-10% of activating agent and 0.1-10% of water softener, wherein the pH value of the refining treating fluid is 4-10; the activating agent is at least one of the following components, i.e. urea, thiourea dioxide, glycerol, dithiothreitol, tricarboxylic ethyl phosphine, beta-mercaptoethanol, carboxymethyl phosphate, peregal-10, ABS (acrylonitrile butadiene styrene), tri-propionitrile base phosphate, tri-N-butylphosphine and tri-(2-carboxyl ethyl phosphate) hydrochloride; and the water softener is sodium tripolyphosphate or sodium hexametaphosphate. The treating method uses the wool refining treating fluid provided by the invention, and adopts a bath one-step method treatment technology; and the treatment technology has the following technological process: cleaning wool-wetting and soaking-refining-washing-softening-drying-refining wool.

Description

technical field [0001] The invention relates to natural wool thinning technology, in particular to a wool thinning treatment liquid and a treatment method. This treatment method utilizes activated biological enzyme reduction technology to process ordinary fine wool into finer wool or ultra-fine wool. Background technique [0002] Wool is an important textile raw material. It has the characteristics of good elasticity, strong moisture absorption, good warmth retention, not easy to stain, and soft luster. Its fabrics also have unique styles and functions. In particular, high-grade light and thin worsted fabrics processed from fine wool (18-21 μm in diameter) and ultra-fine wool (15-8 μm in diameter) are the mainstream products of high-end wool textiles today. However, this kind of animal fiber can only be provided by nature at present. Due to the restriction of natural conditions, the quantity of fine and superfine wool is low and the price is high, which is far from meeting ...
