Abstract

The invention provides a method for treating wool through a biological method. The method comprises: (1) washing a waste keratin material in hot water with a temperature of 55-65 DEG C, drying, and crushing; (2) washing waste shrimp shell and / or crab shell, drying, crushing, carrying out a reaction for 16-25 h at a temperature of 50-75 DEG C in a 3-4% hydrochloric acid solution, washing to achieve a neutral state, and drying; (3) mixing the waste keratin material, the obtained shrimp shell and / or crab shell intermediate material, and distilled water, and carrying out a reaction for 110-130 min at a temperature of 230-240 DEG C to obtain a degradation product solution obtained by dissolving with superheated water; (4) impregnating wool fibers or wool or a whole wool billet cloth in the solution of Na2SO3 Or NaHSO3 and a nonionic surfactant, and treating for 30-40 min at a temperature of 50-70 DEG C; and (5) impregnating in the mixed solution of the 40-100 g / L degradation product dissolved with superheated water and a 5-18% o.w.f Na2SO3 solution, and drying. According to the present invention, the method has advantages of simple process, easy condition control, waste recycling, no chemical reagent introduction, green environmental protection, energy source saving, biocompatibility, and environment friendliness.

Description

technical field [0001] The invention relates to a method for treating wool with a biological method, in particular to a method of degrading waste keratin and pretreated shrimp shells and / or crab shells by using a superheated water method to obtain a degradant solution dissolved in superheated water in wool or wool. Antibacterial, antibacterial, and anti-felting applications for wool products. Background technique [0002] As the earliest natural fiber material used by humans, wool has many excellent properties that other fibers cannot match, such as good elasticity, strong moisture absorption, good warmth retention, not easy to stain, soft luster, etc., making wool textiles have always been used as textiles. An important part of the raw material exists. Wool products of different styles can be made into thin and medium-thick spring, autumn and summer fabrics with good elasticity, smooth hand feeling, thick body and natural luster, and winter fabrics with rich texture, full ...
