Embodiment 1

[0030] The biological decolorization process of the described oxidative method baking oil dyed human hair fiber is as follows:

[0031] (1) Preparation of fermentation broth

[0032] In terms of mass percentage, the components of the liquid fermentation medium are as follows: the addition of oxidative hair dye hair dye is 1.5%, the addition of yeast extract is 0.8%, the addition of sodium chloride is 0.5%, and the addition of dipotassium hydrogen phosphate is 0.5%, the addition of ammonium sulfate is 1.0%, and the balance is water. Based on the total mass of the liquid fermentation medium, inoculate the facultative microorganism strain yeast, and the inoculum amount is 10%. Afterwards, fermentation is carried out at a fermentation temperature of 36°C and a fermentation time of 60 hours to obtain a fermentation broth.

[0033] (2) Pretreatment of human hair fiber dyed by oxidation method

[0034] Take 10kg of human hair fiber dyed by oxidation method, put it into N,N-dimethy...

Embodiment 2

[0040] (1) Preparation of fermentation broth

[0041] In terms of mass percentage, the components of the liquid fermentation medium are as follows: the addition of oxidative method baked oil hair dye pigment is 2.0%, the addition of yeast extract is 1.5%, the addition of sodium chloride is 0.5%, and the addition of dipotassium hydrogen phosphate is 1.0%, the addition of ammonium sulfate is 1.5%, and the balance is water. Based on the total mass of the liquid fermentation medium, Escherichia coli, a facultative microbial strain, was inoculated with an inoculation amount of 8%. Carry out fermentation afterwards, fermentation temperature is 37 ℃, and fermentation time is 65h, obtains fermented liquid

[0042] (2) Pretreatment of human hair fiber dyed by oxidation method

[0043] Take 10kg of human hair fiber dyed by oxidation method, put it into a solution of N,N-dimethylformamide and toluene with a volume ratio of 1:1, bath ratio 1:20, stir, and soak at 30°C for 30 minutes . ...

Embodiment 3

[0049] (1) Preparation of fermentation broth

[0050] In terms of mass percentage, the components of the liquid fermentation medium are as follows: the addition of oxidative hair dye hair dye is 1.2%, the addition of yeast extract is 1.0%, the addition of sodium chloride is 0.5%, and the addition of dipotassium hydrogen phosphate is 0.9%, the amount of ammonium sulfate added is 1.8%, and the balance is water. Based on the total mass of the liquid fermentation medium, inoculate the mixed bacteria of facultative microorganism strain yeast and Escherichia coli, and the inoculum amount is 12%. Afterwards, fermentation is carried out at a fermentation temperature of 32° C. and a fermentation time of 58 hours to obtain a fermentation broth.

[0051] (2) Pretreatment of human hair fiber dyed by oxidation method

[0052]Take 10kg of human hair fiber dyed by oxidation method, put it into a solution of n-butanol and chloroform with a volume ratio of 1:2, bath ratio 1:30, stir and soak...

Abstract

The invention belongs to the technical field of human hair product processing, and in particular relates to a biological decolorization process for human hair fiber dyed with oxidation method. The present invention uses the oxidation-processed hair-dyeing pigment as the only carbon source for fermentation, adds an organic solvent to prepare a fermentation medium, screens and ferments facultative microorganisms that can grow and metabolize using the oxidation-processed hair-dyeing pigment as a carbon source, and obtains a fermentation liquid. Then, adding the pretreated oxidized oil-dyed human hair fiber into the fermentation broth for treatment, thereby removing the pigment in the oxidized oil-dyed human hair fiber. The invention solves the long-term problem that human hair products enterprises cannot decolorize human hair fibers dyed with oxidation method, greatly expands the raw material sources of human hair products enterprises, and reduces the cost of human hair products. In addition, the invention has simple process, good effect, little damage to hair quality, and has very good industrial application prospect.

Description

technical field [0001] The invention belongs to the technical field of human hair product processing, and in particular relates to a biological decolorization process for human hair fiber dyed with oxidation method. Background technique [0002] Along with the raising of people's living standard, the rich and colorful of recreational activities, people often like to change hairstyle, hair color etc. Under normal circumstances, people use the method of hair dyeing to dye their hair. However, due to the disadvantages of skin allergies, carcinogenicity and hair damage in the traditional dyeing process, more and more people tend to use hair sets instead of directly treating hair. Coloring, especially of human hair products prepared from human hair. Since the human hair products prepared from real human hair are closer to real hair in terms of feel and appearance, the market demand for such human hair products is increasing. [0003] The main raw materials of human hair product...
