Problems solved by technology

In the prior art, the above phenomenon can be avoided by selecting the hydrogen peroxide oxidation method, but the hydrogen peroxide oxidation method will inevitably cause damage to the surface of the wool fiber, which will eventually lead to damage to the strength of the wool fiber.

Embodiment 1

[0027] The chlorinated anti-shrinkage mercerizing treatment method of the wool top of embodiment 1 comprises the steps:

[0028] S1: Put the wool top after the needle opening treatment in the penetrating agent aqueous solution with a pH value of 3.5, add a chlorine-containing descaling agent to the aqueous solution, react at room temperature for 20 minutes, and then export the wool top;

[0029] S2: import the wool top obtained in S1 into the reduction treatment solution, raise the temperature to 33°C, keep the temperature for 1.5h, and then raise the temperature to 80°C for 20min;

[0030] S3: Place the wool tops obtained in S2 in a hydrolysis solution containing protease and peptidase, soak at 42°C for 30 minutes, wash and dehydrate with washing solution, and repeat the washing and dehydration operation twice;

[0031] S4: placing the wool obtained in S3 in an aqueous solution containing an anti-shrinkage agent and a softener, washing, drying, and needle carding again to obt...

Embodiment 2

[0035] The difference between Example 2 and Example 1 lies not only in the formula of the treatment solution, but also in the process parameters of dechlorination, reduction, hydrolysis and softening and anti-shrinkage treatment, specifically: the chlorination and anti-shrinkage mercerizing treatment of wool tops in Example 2 The method includes the following steps:

[0036] S1: Put the wool top after the needle opening treatment in the penetrating agent aqueous solution with a pH value of 4.5, add a chlorine-containing descaling agent to the aqueous solution, react at room temperature for 10 minutes, and then export the wool top;

[0037] S2: import the wool top obtained in S1 into the reduction treatment solution, raise the temperature to 38°C, keep the temperature for 1 hour, and then raise the temperature to 90°C and keep it for 10 minutes;

[0038] S3: Place the wool tops obtained in S2 in a hydrolysis solution containing protease and peptidase, soak at 50°C for 20 minutes,...

Embodiment 3

[0043] The chlorinated anti-shrinkage mercerizing treatment method of the wool top of embodiment 3 comprises the steps:

[0044] S1: Put the wool top after the needle card opening treatment in an aqueous penetrant solution with a pH value of 4, add a chlorine-containing descaling agent to the aqueous solution, react at room temperature for 15 minutes, and then export the wool top;

[0045] S2: import the wool top obtained in S1 into the reduction treatment solution, raise the temperature to 35°C, keep the temperature for 1.2h, and then raise the temperature to 85°C for 15min;

[0046] S3: Place the wool top obtained in S2 in a hydrolysis solution containing protease and peptidase, soak at 46°C for 25 minutes, wash and dehydrate with washing solution, and repeat the washing and dehydration operation 3 times;

[0047] S4: soft, the wool obtained in S3 is placed in an aqueous solution containing an anti-shrinkage agent and a softener, washed, dried, and needled again to obtain a ...

Abstract

The invention discloses a chlorinating and shrink-proofing mercerization method for wool tops. The method comprises a wool top chlorinating step, a reduction step, a hydrolysis step, a softening and shrink-proofing step and the like. The wool tops exported from the step S1 are not padded, so that peptide chains, which are not subjected to enzymatic hydrolysis, of scales on the fiber surface are not completely stripped. A penetrant is brought into the reaction in the step S2 along the wool tops, so that improvement of the infiltration capacity of horse radish peroxidase is facilitated, and the rate of enzymatic reaction is accelerated. The wool treated by the method disclosed by the invention is full, and excellent in elasticity; the scales on the wool surface are thoroughly stripped after mercerization; and the wool has relatively high stability in a dye bath or a bleach bath after a shrink-proof agent for softening and shrink-proofing treatment forms a film.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a method for chlorination and anti-shrinkage mercerizing of wool tops. Background technique [0002] The scale layer is a unique structure of wool fiber, which makes wool have special luster and milling performance, but also leads to difficulty in dyeing wool, poor shape stability when washing and itching when wearing. The squamous layer is composed of keratinized flat cells through a cell membrane complex. The principle of mercerizing wool is to use appropriate physical and chemical methods to soften and degrade the scales of wool, so that the scales of wool are damaged and partially or completely peeled off, so as to improve the surface shape of wool fibers and make them feel like cashmere. with gloss. The physical method in the prior art includes the resin increment method, and the chemical method is commonly used the thinning and decrementing method. At present, the common...
