A kind of sub-smooth type artificial hair made from animal protein and preparation method thereof
Technical field
The invention belongs to artificial hair and make the field, be specifically related to a kind of sub-smooth type artificial hair made from animal protein and preparation method thereof.
Background technology
By the patent of invention of patent No. CN200510040450.4, made artificial hair made from animal protein has emulation property preferably, but remains aurora, and the euphorosia sense has much room for improvement.
Summary of the invention
The objective of the invention is to disclose a kind of sub-smooth type artificial hair made from animal protein, to overcome aurora and the uncomfortable shortcoming of visual effect that exists in the existing artificial hair made from animal protein.
Another purpose of the present invention is to provide a kind of preparation method of sub-smooth type artificial hair made from animal protein.
For solving the problems of the technologies described above; Technical scheme of the present invention is: the artificial hair of a kind of sub-smooth type animal protein; Mainly form by blend protein, the matt agent of chemical cross-linking agent, chemical modification; It is characterized in that: said matt agent be egg-white powder through the vexed steaming of steam 1 hour, then 140 ℃ of baking ovens baking 1 hour, the insoluble fine powder that makes through porphyrize and 200 eye mesh screens.
Said chemical cross-linking agent is a hydrazine hydrate.
The blend protein of said chemical modification be with gelatin or the deposition keratin protein be that raw material is processed, dressing agent is a vinyl-type monomer; Said vinyl-type monomer is a kind of in acrylonitrile, methyl methacrylate, butyl methacrylate, the methyl acrylate.
Further; The object of the present invention is to provide a kind of spinning slurry that the sub-smooth type artificial hair made from animal protein is used for preparing, it is characterized in that: said spinning slurry mainly contains vinyl graft copolymer and the spin solvent and the initator of matt agent, protein.The content of said matt agent is the 1-20% of the vinyl graft copolymer of protein.
A kind of preparation method of sub-smooth type artificial hair made from animal protein is specially:
(1) in spin solvent, adds protein, at room temperature stir; Splash into vinyl-type monomer and initator then, solution is heated to 60-85 ℃, react after 3 hours, be cooled to 35 ℃ then gradually, add egg-white powder; Reaction vacuumizes and removes residual vinyl-type monomer after finishing, and it is for use to process spinning slurry;
(2) above-mentioned spinning slurry is extruded in the spinneret cap after deaeration and is got into coagulating bath and become tow;
(3) tow that step (2) is obtained, in boiling water stretching 3-6 doubly, relaxation processes in 110-135 ℃ of hot blast then;
(4) step (3) gained tow was handled 2-3 hour in concentration is 2-12%, temperature 90-99 ℃ hydrazine hydrate aqueous solution, silicone oil, oven dry are gone up in washing at last then, promptly get a kind of sub-smooth type artificial hair made from animal protein.
The adding of vinyl-type monomer described in the step (1) is in batches or disposable adding.The addition of vinyl-type monomer with the ratio of the addition of protein is: 1: 0.1-10.
Said matt agent be egg-white powder through the vexed steaming of steam 1 hour, then 140 ℃ of baking ovens baking 1 hour, the insoluble fine powder that makes through porphyrize and 200 eye mesh screens.
Said initator is azodiisobutyronitrile or ABVN, and its addition is the 0.02-1.5% of vinyl-type monomer weight.
The vinyl graft copolymer of protein content in spinning pulp is 5-14wt%.
The addition of said matt agent is the 1-20% of the vinyl graft copolymer of protein.
In the step (2), be advisable with 0.35-0.45mm in used spinneret cap aperture.
Used spin solvent is sodium thiocyanate water solution or solder(ing)acid.The concentration of sodium thiocyanate water solution is 48-56wt%; The concentration of solder(ing)acid is 55-66wt%.
The used coagulation bath temperature of spinning is advisable with 10-25 ℃.Its concentration is advisable with 20-30wt% as far as sodium thiocyanate water solution; As far as solder(ing)acid, be advisable with 20-40wt%.
Beneficial effect: actual effect of the present invention is the light sense that made artificial hair reduces the plasticity silk, and gloss is soft, sends out near true.
The specific embodiment
Through specific embodiment the present invention is further specified below, following embodiment only be for clearly the present invention is described and is done for example, and be not to be qualification to embodiment of the present invention.For the those of ordinary skill in affiliated field, on the basis of description of contents of the present invention, can also make other multi-form variation or change.Here need not all embodiments are given an example.
Related hair mechanical performance is pressed GB/T14335, GB/T14337 and GB/T14343-2003 and is measured fiber number, tensile strength and elongation in the specific embodiment.
Embodiment 1
(1) deposition keratin protein 200 grams are dissolved in the 3500 gram 58wt% solder(ing)acids, stir down for 25 ℃ in room temperature; In 15 minutes, splash into acrylonitrile 100 grams then, in 20 minutes, splash into azodiisobutyronitrile 0.850 gram and acrylonitrile 240 grams again, constantly stir, solution is heated to 82 ℃, reacts after 3 hours, and cooling gradually then under 35 ℃ temperature, adds matt agent 25 grams; Reaction vacuumizes and removes residual acrylonitrile after finishing, and it is for use to process spinning slurry;
(2) above-mentioned spinning slurry is extruded in the micro-pore diameter 0.45mm spinneret cap after deaeration and is got into coagulating bath and become tow; 25 ℃ of the temperature of said coagulating bath, zinc oxide concentration 21wt%;
The tow of processing desalts with 1% aqueous acetic acid, and acetic acid is removed in the clear water washing then;
(3) with the tow that obtains after step (2) washing, in boiling water, stretch 4.2 times, then relaxation processes in 120 ℃ of hot blasts;
(4) step (3) gained tow is 5% in concentration, handled 45 minutes in the hydrazine hydrate aqueous solution of 95 ℃ of temperature, silicone oil, oven dry are gone up in washing at last then, promptly get a kind of sub-smooth type artificial hair made from animal protein.
Said matt agent be egg-white powder through the vexed steaming of steam 1 hour, then 140 ℃ of baking ovens baking 1 hour, the insoluble fine powder that makes through porphyrize and 200 eye mesh screens.
The artificial hair of processing is filament number 55dtex, tensile strength 2.0CN/dtex, elongation 33%; Visual effect is good, electrodeless polished bard eye.
Embodiment 2
1. precipitate keratin protein 200 grams and be dissolved in the 3500 gram 58w% solder(ing)acids, stir down for 25 ℃ in room temperature; In 15 minutes, splash into acrylonitrile 100 grams then, in 20 minutes, splash into azodiisobutyronitrile 0.850 gram and acrylonitrile 240 grams again, constantly stir; Solution is heated to 82 ℃; React after 3 hours, cooling gradually then is under 35 ℃ temperature; Add matt agent 20 grams and 300 purpose carbon powders, 5 grams, stir; Reaction vacuumizes and removes residual acrylonitrile after finishing, and it is for use to process spinning slurry;
Said matt agent is used with embodiment 1.
Following steps are with the step among the embodiment 1 (2), (3), (4), (5).
The black artificial hair of processing thus, filament number 50dtex, tensile strength 2.ICN/dtex, elongation 31%; Visual effect is good, and gloss is soft.
Comparative example
Matt agent is used titanium white powder 0.3wt%, and all the other are with embodiment 1.Prepared artificial hair, its matt effect is inflexible, the outward appearance lackluster.
Titanium white powder is the TA-301 of Japanese fuji titanium Co., Ltd. system.
