Problems solved by technology

However, according to the current relevant research reports, the contradiction between the whiteness, yield and strength of human hair fiber bleaching has not been effectively overcome. A high yield, high whiteness, and low damage human hair fiber bleaching process At the same time, the bleaching process that is applicable to the process improvement of existing enterprises is a dual need to improve product quality and meet market demand

Embodiment 1

[0036] (1) Pretreatment of human hair fiber by pretreatment liquid:

[0037] The ferrous ions in the pretreatment solution have a good adsorption effect on the melanin in the protein fiber, and at the same time can realize the catalytic decomposition of hydrogen peroxide. Add 35g / L tartaric acid and 20g / L ferrous sulfate solution to the dry human hair fiber, the bath ratio is 1:8, and the constant temperature of the water bath is 80°C for 3h.

[0038] (2) Batch-feeding oxidatively bleached human hair fibers:

[0039] Oxidative bleaching agent decomposes and releases active oxygen during bleaching, and then the active oxygen acts on the chromophoric group of melanin, destroying the pigment structure and decolorizing the fiber. At the same time, it will also strongly damage the hair keratin, break the disulfide bond between the horny macromolecules, and cause serious damage to the hair fiber. And the large amount of energy released when hydrogen peroxide decomposes can promote...

[0048] (1) Pretreatment of human hair fiber by pretreatment liquid:

[0049] The ferrous ions in the pretreatment solution have a good adsorption effect on the melanin in the protein fiber, and at the same time can realize the catalytic decomposition of hydrogen peroxide. Add 35g / L tartaric acid and 20g / L ferrous sulfate solution to the dry human hair fiber, the bath ratio is 1:8, and the constant temperature of the water bath is 80°C for 3h.

[0050] (2) Batch-feeding oxidatively bleached human hair fibers:

[0051] Oxidative bleaching agent decomposes and releases active oxygen during bleaching, and then the active oxygen acts on the chromophoric group of melanin, destroying the pigment structure and decolorizing the fiber. At the same time, it will also strongly damage the hair keratin, break the disulfide bond between the horny macromolecules, and cause serious damage to the hair fiber.

[0061] (1) Pretreatment of human hair fiber by pretreatment liquid:

[0062] The ferrous ions in the pretreatment solution have a good adsorption effect on the melanin in the protein fiber, and at the same time can realize the catalytic decomposition of hydrogen peroxide. Add 35g / L tartaric acid and 20g / L ferrous sulfate solution to the dry human hair fiber, the bath ratio is 1:8, and the constant temperature of the water bath is 80°C for 3h.

[0063] (2) Batch-feeding oxidatively bleached human hair fibers:

[0064] Oxidative bleaching agent decomposes and releases active oxygen during bleaching, and then the active oxygen acts on the chromophoric group of melanin, destroying the pigment structure and decolorizing the fiber. At the same time, it will also strongly damage the hair keratin, break the disulfide bond between the horny macromolecules, and cause serious damage to the hair fiber.

Abstract

The invention discloses a human hair fiber bleaching process, comprising the following steps: (1) surface pretreatment of human hair fibers; (2) batch feeding oxidation treatment of pretreated human hair fibers; (3) human hair fibers after oxidation treatment Restoration of hair fibers. The invention has simple process, low cost and easy industrialization, solves the problems of low yield and large fiber damage in the process of human hair fiber bleaching, and has good development prospect and economic value.

Description

technical field [0001] The invention belongs to the field of textile dyeing and finishing, in particular to a process for bleaching human hair fibers. Background technique [0002] With the improvement of living standards, wigs have become a must-have for people with scarce hair and beauty lovers. These people need wigs of more colors to dress themselves up. In addition, as a beauty-loving fashion, wearing wigs is deeply loved by many stars, actors and high-consumption groups, and people update wigs more and more frequently, which promotes the development of the wig industry. Although chemical fiber wigs are bright in color and cheap, if they are worn for too long, they will cause discomfort such as stuffiness and dryness, and may even cause skin diseases. Human hair is a natural fiber, and its moisture absorption, air permeability and flame retardancy are far better than chemical fiber wigs, so wigs made of human hair are still people's first choice. The hair color of Chi...
