Problems solved by technology

At present, the known wigs are mainly made of human hair and chemical crude fiber. Human hair is extremely scarce and expensive. Chemical fiber hair has many disadvantages, such as irritating the skin, causing allergies and being flammable. Once burned, it will melt into a melt and burn the skin. , the hidden danger is great, some other protein-containing hair materials and variegated human hair need secondary dyeing, and cause pollution to the environment

Embodiment 1

[0006] When the present invention is implemented, it can be realized by the following scheme, by weight: 45 parts of milk protein, 49 parts of polyvinyl alcohol, 0.2 part of crosslinking agent sodium borate, 4 parts of phthalocyanine blue BS, flame retardant trioctyl phosphate 1.8 parts as raw material, first soak milk protein in warm water at 32°C for 2.5 hours, then add sodium hydroxide to adjust the pH value to 7.8, then raise the temperature to 100°C, keep it warm for 4 minutes, and then cool down to 90°C to dissolve the protein into The milk protein aqueous solution with a mass concentration of 22% is ready for use; soak the polyvinyl alcohol in warm water at 30°C for 3 hours, send it to a dissolving machine and heat it up to 90°C, and stir for 120 minutes to completely dissolve the polyvinyl alcohol and become a solution with a mass concentration of 23°C. % polyvinyl alcohol aqueous solution; add the dissolved milk protein aqueous solution into the polyvinyl alcohol aqueo...

Embodiment 2

[0008] The present invention can also be by weight: 50 parts of milk protein, 44 parts of polyvinyl alcohol, 0.2 part of crosslinking agent sodium borate, 4 parts of purple caramel base G (GC), 1.8 parts of flame retardant trioctyl phosphate as raw materials, wherein Soak the milk protein at 33°C for 3 hours, add sodium hydroxide to adjust the pH value to 7.8, then raise the temperature to 100°C, keep it warm for 4 minutes, and then cool down to 90°C to dissolve the protein in milk with a mass concentration of 23%. The protein aqueous solution is ready for use; soak the polyvinyl alcohol in warm water at 30°C for 3 hours, send it to a dissolving machine and heat it up to 100°C, and stir for 120 minutes to completely dissolve the polyvinyl alcohol into an aqueous solution with a mass concentration of 25%; put the dissolved Add the milk protein aqueous solution into the polyvinyl alcohol aqueous solution, stir evenly, add the pigment purple caramel G (GC), after stirring for 60 m...

Embodiment 3

[0010] The present invention can also be realized by following technical scheme, adopt by weight: casein 588kg, polyvinyl alcohol 991kg, crosslinking agent sodium borate 3.5kg, pigment 70kg, fire retardant trioctyl phosphate 31.5kg make raw material, wherein first After soaking milk protein in 35°C for 3.5 hours, add sodium hydroxide to adjust the pH value to 7.7, then raise the temperature to 100°C, keep it warm for 4 minutes, then cool down to 90°C, so that the protein dissolved mass concentration is 25% for later use; Soak vinyl alcohol in warm water at 30°C for 3 hours, put it into a dissolving machine and heat up to 98°C, and stir for 120 minutes to completely dissolve polyvinyl alcohol into an aqueous solution with a mass concentration of 28%; add the dissolved milk protein aqueous solution to polyethylene In the alcohol aqueous solution, after stirring evenly, add the pigment phthalocyanine blue BS, stir for 60 minutes, add the crosslinking agent sodium borate, stir for ...

Abstract

The invention relates to a method for producing bleached and dyed milk protein hairs, aiming at effectively solving the problems that fake hairs can stimulate the skin and cause the skin allergy and are inflammable. The method for producing the bleached and dyed milk protein hairs from the raw materials of milk protein, polyvinyl alcohol, crosslinking agent of sodium borate, pigment, flame retardant of trioctyl phosphate comprises the following steps: soaking the milk protein in warm water and adjusting the pH value of the milk protein to make the milk protein dissolved into the aqueous solution of the milk protein; soaking the polyvinyl alcohol in water to make the polyvinyl alcohol fully dissolved into the aqueous solution of the polyvinyl alcohol; adding and stirring evenly the aqueoussolution of the milk protein to the aqueous solution of the polyvinyl alcohol; adding and stirring evenly the pigment, the sodium borate and the trioctyl phosphate to the mixture of the aqueous solution of the milk protein and the aqueous solution of the polyvinyl alcohol to prepare spinning solution; standing and defoaming the spinning solution; delivering the spinning solution into a spinning machine to dewater the spinning solution and solidify the spinning solution into filament; collecting the solidified filament, drying, preheating, stretching and shaping, concentrating the acetal in the filament with the hydroformylation bath, washing the filament with water, removing the aldehyde in the filament and softening the filament to obtain the bleached and dyed milk protein hairs. The method for producing bleached and dyed milk protein hairs is advanced and ensures that the product of bleached and dyed milk protein hairs has good quality and no side effect, is comfortable to wear, is similar to real hairs and has good decorative effect. The bleached and dyed milk protein hairs are innovation on the fake hairs.

Description

1. Technical field [0001] The invention relates to a wig, in particular to a method for producing milk protein colored hair synthesized with milk protein, polyvinyl alcohol and pigments. 2. Background technology [0002] Wigs are common items used by people to decorate their heads, especially with the improvement of people's lives today, it is common for some people with defective or dissatisfied hair to decorate with wigs, and the demand for wigs is increasing day by day. At present, the known wigs are mainly made of human hair and chemical crude fiber. Human hair is extremely scarce and expensive. Chemical fiber hair has many disadvantages, such as irritating the skin, causing allergies and being flammable. Once burned, it will melt into a melt and burn the skin. , The hidden danger is very big, and some other hair-making materials containing protein and variegated human hair all need secondary dyeing, causing pollution to the environment again. Therefore, improvement and...
