Abstract

The invention provides a mink down hair bleaching processing method. According to the method, the treatments including alkali cleaning, retanning, medium, bleaching, iron removal and retanning are performed on the mink. According to the method, as the treatments including alkali cleaning, retanning, medium, bleaching, iron removal and retanning are performed on the mink, the problem of fur matching is solved, and after the bleaching treatment of the mink down hair, the down hair is clean without impurities, fluffy and natural, and high in moldability; besides, the colors of the mink fabrics can be selected randomly.

Description

Fur bleaching under hair processing method

Technical field

The present invention relates to fur processing technology field, be specifically related to a kind of fur bleaching under hair processing method.

Background technology

Along with the development of leather and fur industry, white mink clothes are more favored by people, and white fur limited amount, and color is also variant, all the time this put at fur products manufacturing enterprise and a great problem of joining in face of skin workman.A kind of fur bleaching under hair processing method will thoroughly solve fur clothes and goods to this bottleneck problem of the requirement of fur color.

Summary of the invention

The invention provides a kind of fur bleaching under hair processing method, the problem of skin difficulty joined by the fur existed to solve prior art.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of fur bleaching under hair processing method, fur is adopted to alkali cleaning, retanning, medium, bleaches, takes off iron and retanning process, and concrete technology step is as follows:

(1) alkali cleaning: at 32 DEG C, fur alkali cleaning process 2 hours, adds salt 40g, adds soda ash 4g in often liter of alkali wash water, add ammoniacal liquor 2ml in often liter of alkali wash water in often liter of alkali wash water, add wetting agent HAC 2ml in often liter of alkali wash water, then goes out skin cleaning;

(2) retanning: at 35 DEG C, is immersed in tanning solution, and tanning solution pH value controls between 6.5 ~ 7, and saliferous 40g in often liter of tanning solution, adds formaldehyde 7 ~ 10ml, next day in often liter of tanning solution, go out skin, cleaning;

(3) medium: at 32 DEG C, is immersed in medium liquid, and medium liquid pH value controls between 6.5 ~ 7, and saliferous 40g in often liter of medium liquid, adds ferrous sulfate 10g, next day in often liter of medium liquid, go out skin, cleaning;

(4) bleach: at 35 DEG C, to fur bleaching, often liter of bleaching liquid salt addition is 40g, often liter of bleaching liquid adds bleaching assistant BLEACH ASSIST MB5ml, to bleach after 15 minutes the hydrogen peroxide 20ml that often liter of bleaching liquid adds 30%, after 1 hour, often liter of bleaching liquid adds the hydrogen peroxide 20ml of 30% again, more often liter of bleaching liquid adds the hydrogen peroxide 20ml of 30% after 1 hour, then after 4 hours, goes out skin and salt is washed;

(5) take off iron: at 35 DEG C, iron process is taken off to fur, saliferous 40g in often liter for the treatment of fluid, containing oxalic acid 2g in often liter for the treatment of fluid, containing bleaching agent AP3g in often liter for the treatment of fluid, after two hours, go out skin cleaning water dumping;

(6) retanning: at 32 DEG C, be immersed in tanning solution, saliferous 40g in often liter of tanning solution, alum 35g is added in often liter of tanning solution, add in often liter of tanning solution and protect hair agent 0.5ml, go out skin, drying, rotary drum brush oil, hold over night, elongate, stretch wide, rotary drum, again through degreasing, turn light, arrange and terminate.

Present invention process method, by adopting alkali cleaning, retanning, medium to fur, bleach, take off iron and retanning process, not only solves the problem of joining skin, after the process of fur bleaching under hair, the pure white free from admixture of lint, fluffy nature, plasticity is strong, allows the color of fur fabric follow one's bent.
