Embodiment 1

[0017] Add the compound amino acid and ferrous sulfate obtained by hydrolyzing keratin into water, so that the concentration of compound amino acid is 3g / L, and the concentration of ferrous sulfate is 5g / L, and stir for 20 minutes; heat up to 50°C, add human hair to be treated Fiber, make the mass ratio of human hair fiber to water 1:15, soak for 20 minutes; add hydrogen peroxide with a concentration of 30%, make the mass ratio of hydrogen peroxide to human hair fiber 0.5:1, bleach for 50 minutes, take out the human hair Fiber, washed. The whiteness, breaking strength and yield of the product are shown in Table 1.

Embodiment 2

[0019] Add the compound amino acid and ferrous sulfate obtained by hydrolyzing keratin into water so that the concentration of the compound amino acid is 1g / L, and the concentration of ferrous sulfate is 3g / L. Stir and react for 30 minutes; raise the temperature to 60°C, add human hair to be treated fiber, make the mass ratio of human hair fiber to water 1:5, soak for 30 minutes; add 30% hydrogen peroxide, make the mass ratio of hydrogen peroxide and human hair fiber 2:1, bleach for 30 minutes, take out the human hair Fiber, washed. The whiteness, breaking strength and yield of the product are shown in Table 1.

Embodiment 3

[0021] Add the compound amino acid and ferrous sulfate obtained by hydrolyzing keratin into water, so that the concentration of compound amino acid is 5g / L, and the concentration of ferrous sulfate is 10g / L, and stir for 10 minutes; heat up to 40°C, add human hair to be treated fibers, so that the mass ratio of human hair fibers to water is 1:30, soak for 10 minutes; add hydrogen peroxide, so that the mass ratio of 30% hydrogen peroxide to human hair fibers is 0.3:1, bleach for 100 minutes, take out the human hair Fiber, washed. The whiteness, breaking strength and yield of the product are shown in Table 1.

Abstract

The invention provides a method for bleaching complexing catalysis human hair fibers. The method is characterized by comprising the following steps that 1) compound amino acid and ferrous sulfate areadded into water, so that the concentration of the compound amino acid is 1-5 g / L, the concentration of the ferrous sulfate is 3-10 g / L, and a stirring reaction is carried out for 10-30 minutes; 2) the temperature rises to 40-60 DEG C, and the human hair fibers are added into the solution prepared in step 1), so that the mass ratio of the human hair fibers to water is 1:(5-30), and soaking is carried out for 10-30 minutes; 3) hydrogen peroxide is added, so that the mass ratio of the hydrogen peroxide to the human hair fibers is (0.3-2):1, bleaching treatment is carried out for 30-100 minutes,and the human hair fibers are taken out and washed. The compound amino acid is prepared by hydrolyzing keratin. According to the provided technical scheme, the method has the advantages of high bleaching efficiency and small damage to the human hair fibers.

Description

technical field [0001] The invention relates to a method for bleaching human hair fibers, in particular to a method for complexing and catalyzing the bleaching of human hair fibers, and belongs to the field of hair product processing. Background technique [0002] With the improvement of the quality of life, the practicality and fashion of wigs have been recognized by people, and gradually become daily consumer goods. According to the type of raw materials, wigs can be divided into two categories: chemical fiber silk and human hair. Among them, wigs made of human hair have the advantages of high fidelity, not easy to knot, and no side effects on the scalp. Therefore, high-end wigs are made of human hair fiber. [0003] At present, the human hair fibers used to make wigs mainly come from China, India, Pakistan and other Asian regions, and the color of human hair fibers is mainly black. However, modern people need to diversify the color of wigs, and the required colors of t...
