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...
