Abstract

The invention discloses an electrochemical bleaching and setting process for ultrasonic-plasma pretreatment of black horsetail hair. The process includes washing the black horsetail hair with a detergent, adding medium water, and preforming ultrasonic treatment; then adopting a plasma technology to preform pretreatment; dissolving penetrants of fatty alcohol polyoxyethylene ether and sodium silicate in water, adjusting the pH value, adding hydrogen peroxide, heating the solution, fixing the obtained pretreated black horsetail hair on an anode of a graphite electrode, setting electric field power, preforming electrochemical bleaching treatment, washing with water, and drying; soaking the bleached and decolorized horsetail hair in distilled water, controlling the water content, setting the setting temperature, and setting in wet heat; and stretching and thinning the wet heat-set horsetail hair, pre-steaming and then stretching, steaming, washing with water, treating the hair with a setting agent, steaming and setting, washing with water, treating with boiling water, and air drying.

Description

technical field [0001] The invention belongs to the field of horsetail processing, and in particular relates to an electrochemical bleaching and shaping process for ultrasonic-plasma pretreatment of 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. I...
