Embodiment 1

[0031] A kind of catalase catalyzed bleaching and decolorization process of black horsetail hair, is characterized in that, comprises the steps:

[0032] (1) Infiltration pretreatment:

[0033] Soak the black horsetail hair in water for 5 minutes to remove sweat stains and other impurities on the surface, put it into the infiltration pretreatment solution at a bath ratio of 1:10, and infiltrate the pretreatment solution at a pH of 6 and a temperature of 40-50°C for 1 hour. Wash with water and cold water in sequence;

[0034] (2) Scaling:

[0035] Acid treatment, oxidation and scale removal first: put the horsetail hair after permeation pretreatment into the acid treatment solution, the bath ratio is 1:10, stir for 5 minutes, take it out, and wash it with water twice;

[0036] Protease descaling: Put the acid-treated, oxidized and descaled horsetail hair into the protease treatment solution at a bath ratio of 1:10, the pH is 7, soak at a constant temperature of 40-50°C for 70...

Abstract

A black horsetail hair catalytic bleaching and decolorization process utilizing catalase is disclosed. The process includes soaking black horsetail hair in water to remove surface sweat and other impurities; adding the horsetail hair into a permeation pretreatment liquid for permeation pretreatment, taking the horsetail hair out, and washing the horsetail hair with hot water and cold water in order; stirring the horsetail hair after permeation pretreatment in an acid treatment solution, taking the horsetail hair out, and washing the horsetail hair with clear water; then subjecting the horsetail hair after oxidation and scale stripping through acid treatment to constant-temperature soaking treatment in a protease treatment solution, taking the horsetail hair out, and washing the horsetail hair with clear water; in a sealed environment, subjecting the horsetail hair after scale stripping to heating treatment in a catalytic treatment solution, taking the horsetail hair out and washing thehorsetail hair with water; subjecting the horsetail hair after complexing catalysis to temperature maintaining and bleaching in a bleaching solution, taking the horsetail hair out and washing the horsetail hair with water; adding the bleached horsetail hair into a catalase bleaching solution, adjusting the pH of the solution with diluted acetic acid or diluted aqueous ammonia until the pH is neutral, bleaching the horsetail hair in a water bath, taking the horsetail hair out, washing and drying the horsetail hair; and treating the bleached horsetail hair in a solution containing a flourescentbrightener, and cleaning and drying the horsetail hair.

Description

technical field [0001] The invention belongs to the field of horsetail processing, and in particular relates to a catalase-catalyzed bleaching and decolorization process for black horsetail hair. Background technique [0002] Horsetail hair is widely used in carded wool spinning products because of its good elasticity, bending resistance, impact resistance, soft luster, plumpness, good air permeability and smooth wool feeling. Value and moderate price win the favor of consumers all over the world. It is understood that the chest interlining and shoulder pad interlining of modern high-end suits and women's clothing are basically made of natural ponytail interlining. But, because horsetail hair color and luster is relatively monotonous and black is in the majority, so most of them are unfavorable for dyeing required bright colors, can only do dark color product, and this has directly influenced the development and the utilization of horsetail hair. In order to further develo...
