[0027] (2) Put the descaled human hair fibers into the pre-medium treatment solution and treat them for 55 minutes at 55°C and pH 3. After the treatment, take out the hair fibers, wash them, and dry them for the next step. , wherein the pre-medium treatment solution consists of: 6g / L ferrous sulfate, 0.35g / L thiourea dioxide, 0.15g / L glucose and 1.5g / L hydrosulfite, and the solvent is water;

[0028] (3) Put the human hair fiber treated with the pre-media into the complexing cleaning solution, and treat it at room temperature for 10 minutes, wherein the complexing cleaning sol...

Embodiment 3

[0033] (1) Put the human hair fiber into the descaling agent solution, descale the treatment at 25°C for 30 minutes, take out the human hair fiber after treatment, wash it with water, and dry it for the treatment of the next step, wherein the descaling The composition of agent is: 46g / L sodium hypochlorite, 3g / L peracetic acid, 2.5g / L sodium bicarbonate and 6g / L vitriol oil, solvent is water;

[0034] (2) Put the descaled human hair fibers into the pre-medium treatment solution and treat them for 70 minutes at 60°C and pH 4. After the treatment, take out the hair fibers, wash them, and dry them for the next step. , wherein the pre-media treatment solution consists of: 8g / L ferrous sulfate, 0.5g / L thiourea dioxide, 0.2g / L glucose and 2g / L hydrosulfite, and the rest is water.

[0035] (3) Put the pre-medium-treated human hair fiber into the complexing cleaning solution, and treat it at room temperature for 15 minutes, wherein the composition of the complexing cleaning solution i...

Abstract

The invention relates to a method for bleaching human hair fibers at low temperature with low damage, which comprises the following steps of: (1) placing the human hair fibers into a scaling agent and performing scaling treatment for 10 to 30 min; (2) placing the scaled human hair fibers into a pre-mordanting treatment fluid, and performing pre-mordanting treatment for 40 to 70 min; (3) placing the pre-mordanted human hair fibers into complexing cleaning solution, and performing complexing cleaning at room temperature for 5 to 15 min; and (4) placing the complexing-cleaned human hair fibers into low-temperature activation bleaching solution, and performing treatment for 60 to 100 min. The method ensures simplicity and low cost, easily realizes industrial production, overcomes the shortcomings of more pollutions, high water consumption, high energy consumption, high damage to the human hair fibers and the like in a conventional human hair bleaching process, can improve the whiteness ofthe bleached fibers, reduce the bleaching cost and avoid water body pollutions, and has vast application prospect and economic benefits.

Description

technical field [0001] The invention belongs to the field of bleaching of human hair fibers, in particular to a low-temperature and low-damage bleaching method for human hair fibers. Background technique [0002] With the improvement of living standards, people have higher requirements for their appearance. In recent years, the number of people with hair loss has increased sharply. These people need more colorful wigs to decorate themselves, which promotes the development of the wig industry. In the international market, wigs made of human hair are particularly precious. Due to historical and cultural customs, Asians have the custom of hair storage and hair care. The hair is long and easy to weave into wigs of various specifications. Hair sets made of Asian hair are of higher quality and are popular among European and American consumers. like. But the human hair fibers of most Asians contain natural pigments, all with different colors such as black and dark brown, so it i...
