Embodiment 1

[0020] The processing method of worm's ovum in the cashmere fabric of embodiment 1 comprises the following steps:

[0021] S1: Put the cashmere fabric in deionized water, heat it to 50°C, wash it under ultrasonic conditions, and dry it;

[0022] S2: Enzyme treatment solution is prepared. The main components of the enzyme treatment solution are cutinase, protease, glycoside hydrolase, pH regulator and water. The pH value of the enzyme treatment solution is 7.5-7.6;

[0023] S3: placing the cashmere fabric obtained in S1 in the enzyme treatment liquid, heating up and keeping warm for reaction;

[0024] S4: Take out the cashmere fabric, transfer the liquid into a steaming device to steam the cashmere fabric, wash and dry it.

[0025] The cutinase in the enzyme treatment solution is fusca cutinase, and the concentration of cutinase in the enzyme treatment solution is 10 mg / L; the concentration of protease is 0.3 mg / L; the concentration of glycoside hydrolase is 4 mg / L.

[0026] ...

Embodiment 2

[0030] Embodiment 2 is based on embodiment 1, and the difference is that the deionized water washing temperature in S1 is 60° C.; the pH value of the enzyme treatment solution is 7.7 to 7.9; the concentration of cutinase in the enzyme treatment solution is 5 mg / L; the concentration of protease 1 mg / L; the concentration of glycoside hydrolase is 1.5mg / L.

[0031] The treatment time of the cashmere fabric in the enzyme treatment solution is 8 hours, and the temperature of the heat preservation reaction is 50°C.

[0032] Steaming time is 2min.

Embodiment 3

[0034] Example 3 is based on Example 1, the difference is that the deionized water washing temperature in S1 is 55°C; the concentration of cutinase in the enzyme treatment solution is 8 mg / L; the concentration of protease is 0.7 mg / L; the concentration of glycoside hydrolase It is 2.5mg / L.

[0035] The treatment time of the cashmere fabric in the enzyme treatment solution is 7 hours, and the temperature of the heat preservation reaction is 55°C.

[0036] Steaming time is 8min.

Abstract

The invention discloses a treatment method of worm egg shells in a cashmere fabric. The method comprises the steps of pre-washing, preparation of an enzyme treatment solution, an enzyme treatment reaction, steaming, washing, drying and the like. According to the treatment method of the worm egg shells in the cashmere fabric, scale layers of cashmere fibers and the worm egg shells are simultaneously hydrolyzed by a compound enzyme composed of cutinase, protease and glucoside hydrolase. Steaming helps to increase the breakage probability of the worm egg shells, the treated cashmere fabric is softer in hand feeling, and the local color depth caused by the worm egg shells is improved.

Description

technical field [0001] The invention relates to the technical field of cashmere fabric production, in particular to a method for treating insect eggshells in cashmere fabrics. Background technique [0002] Cashmere is a special animal wool fiber. Animals usually have protein-eating parasites attached to them. Therefore, the cashmere fibers will attach the shells of parasites after death, that is, egg shells. The egg shells and fibers are entangled together, and a small part of the egg shells are deeply entangled with the cashmere. The existing cashmere carding process cannot be completely removed, and increasing the carding intensity will inevitably cause mechanical damage to the cashmere. Insect egg shell is a combination of chitin and protein, usually in the shape of a cyst with an oblate opening and a cavity. The material of the cyst wall is relatively loose, and it has a better affinity for dyes. , The dye is also easy to enter the cavity, resulting in the deposition of...
