Embodiment Construction

[0019] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0020] A kind of anti-shrinkage processing method of woolen fabric of the present invention, concrete steps are:

[0021] (1) Oxidation pretreatment: immerse the woolen fabric in a 20-40% oxidizing solution for oxidation treatment. Treatment conditions: PH: 7-8, temperature 30-50°C, time: 20-30min, bath ratio: 1:30-40, oxidizing agent dosage is 3-5% of cloth weight; the oxidizing agent is preferably hydrogen peroxide or peracetic acid .

[0022] (2) Modification treatment: the finished product of step (1) is immersed in a protease solution for treatment. Treatment conditions: PH: 7-8, temperature 30-60°C, time: 30-50min, bath ratio: 1:30-40, pr...

Abstract

The invention discloses a shrink-resistance treatment method of wool textiles. The shrink-resistance treatment method comprises the following specific steps of: oxidization pretreatment; modifying treatment; rinsing; prebaking; ironing; and baking. According to the invention, an oxidant is used for treating the wool textiles first so as to facilitate decrement activity of protease to wool. Long-carbon-chain lipoid on the surface of the wool can be removed by oxidant pretreatment, so that scales are loose, expansive and soft, and protease molecules easily enter inside for hydrolyzing wool scales during protease treatment, and the shrink resistance effect after finishing is good; meanwhile, in the whole treating process, the advantages of low temperature, less energy consumption, no toxic and harmful matters and no environment pollution are achieved.

Description

technical field [0001] The invention discloses a wool fabric treatment method, in particular to a wool fabric anti-shrinkage treatment method. Background technique [0002] As a natural protein fiber, wool has many excellent properties that other fibers cannot match, such as good elasticity, soft luster, strong hygroscopicity, not easy to stain, good warmth retention, etc., so it has always been favored by consumers. However, the particularity of the surface structure causes the wool fiber to have a tendency to feel and shrink, which greatly affects the style and dimensional stability of the woolen fabric. burden. [0003] In order to make wool fabrics like synthetic fibers, can be washed by ordinary hand or household washing machines, anti-shrink finishing is required. At present, more than 90% of shrink-resistant wool has been treated with chlorine and its derivatives. The process has the advantages of low cost and good anti-shrinkage effect. However, during the chlori...
