Problems solved by technology

This method can make the wool fabric meet the machine washable standard, the fabric feels better, the cost is low and the output is high, but the absorbable organic halide (AOX) produced by the wool chlorination process is very toxic, causing serious ecological environment pollution, laws in many developed countries have restricted the use of

Embodiment Construction

[0018] A method for preventing felting of possum hair fiber pretreated with protease according to the present invention will be further described in detail through specific examples below.

[0019] Such as figure 1 Shown, a kind of opossum hair fiber anti-felting method utilizing protease pretreatment comprises the steps:

[0020] (1) Pretreatment: place the possum hair fiber in a solvent with a mass fraction of 1% Ping Ping O, heat wash it at 40-50° C. for 1 hour, and finally wash it with ethanol and hot water to remove residual impurities in the fiber;

[0021] (2) Oxidation treatment of fibers: at normal temperature, a hydrogen peroxide mixed solution is configured, and the fibers are placed in the mixed solution to react;

[0022] Oxidation treatment process conditions: the treatment bath is a solution containing 4-6% hydrogen peroxide with a mass concentration of 30%, pH 3.0-5.0, normal temperature, and treatment time 20-40min;

[0023] (3) reduction treatment of fiber:...

Abstract

The invention relates to a possum hair fiber anti-felting method with protease for pretreatment. The method comprises the steps that firstly, free oily impurities are removed in peregal O; then oxidation treatment is carried out with hydrogen peroxide to improve the hydrophilia of the surfaces of the fibers; then reduction is carried out in sodium hydrogen sulfite and sodium carbonate, and then a decrement reaction is carried out in a protease solution; finally, protease is subjected to inactivation treatment. By means of the method, protease is used for the possum hair anti-felting treatment technology which is an ecological anti-felting technology most possible to replace chlorination anti-felting, and protection of the ecological environment is promoted; on the other hand, the structure of possum hair cytomembrane compounds can be changed after treatment, the dispersing capability of dye molecules in the region can be improved, dyeing potential energy can be reduced, the dyeing activity of hair fibers can be improved, and thus low-temperature dyeing of hair can be achieved.

Description

【Technical field】 [0001] The invention relates to a method for preventing felting of possum hair fibers by using protease treatment, which belongs to the applied technology research on possum hair fiber processing. 【Background technique】 [0002] The surface morphology of possum hair fiber scales, if there are cracks, the shape of the scale edge is mainly jagged, ring, petal, tile. The scales are high in height and large inclination angle, and there is no mosaic connection between scales. As a result, the fabric has poor wettability and high felt shrinkage. In order to improve the wearing performance of possum wool fabrics, such as good gloss, anti-felting, soft touch, bright color, not easy to pilling, etc., so as to meet the needs of "machine washable" easy-care finishing. [0003] At this stage, the anti-felting treatment of wool is mainly done by the chlorination-Hexeter finishing method, that is, the scale layer is first destroyed by a chlorine-containing oxidant, and...
