Description

A kind of spinning is with hair-keratin matter solution
Technical field
The present invention relates to a kind of spinning with hair protein matter solution, also relate to a kind of preparation method and application of this protein soln simultaneously, belong to the comprehensive utilization field of hair raw material.
Technical background
Keratin sulfate (Keratin) claim insoluble fibrin again, be constitute that horn matter comprises hair, sends out, plumage, first, angle, hoof, squama etc.In the hair molecular structure of keratin protein very closely, laterally crosslinked between the protein molecule segment through chemical bonds such as disulfide linkage, make it have the cyberspace structure, therefore can not be dissolved in usual vehicle, show dissolving, the fused characteristics not of being difficult for.Make hair-keratin matter dissolving, will at first destroy disulfide linkage between keratin molecule, hydrogen bond etc., generally can adopt highly basic dissolution method, oxidation style dissolving, reduction method dissolving etc.
Summary of the invention
The object of the present invention is to provide a kind of spinning with hair protein matter solution,, improve solvability to reduce cost.
Simultaneously, the present invention also aims to provide the preparation method of a kind of spinning with hair protein matter solution.
Further, the present invention also aims to provide a kind of spinning with of the application of hair protein matter solution as spinning protein fibre aspect.
To achieve these goals, technical scheme of the present invention has adopted a kind of spinning with hair protein matter solution, is prepared by following method: (1) hair cleans and removal of impurities; (2) will clean and removal of impurities after hair join in the alkali lye and dissolve; (3) with the Hydrogen chloride of concentration 15~20%, slowly join while stirring in the good hair protein matter solution of step (2) dissolving, be neutralized to pH=7.5~8.5; (4) spinning: the protein liquid after will neutralizing carries out spinning, removes the above solid impurity of 5 μ m, obtains more purified hair protein matter solution; (5) clarification filtration: in the hair protein matter solution that step (4) makes, add flocculating aids, carry out the essence filter, obtain the protein soln of clear; (6) ultrafiltration desalination and filtering micromolecular compound: the ultra-filtration membrane of selecting molecular weight cut-off 3000~10000 for use; Remove salinity and most micromolecular compound more than 90%; Make protein content in solution reach 6~10%, the spinning that is met the requirement of spinning hair-keratin matter conjugated fibre is with hair-keratin matter solution.
The described hair of step (1) cleans and removal of impurities is: when the raw material that is adopted is the pig hair, after the pig hair dried, remove the coffin in the pig hair, the impurity that sandstone weight is bigger earlier; Scurf in removing the pig hair, impurity that sandy soil are tiny again; After length classifying machine is isolated longer dimension, the higher bristles of economic worth, remaining pig undercoat is beaten through the water unhairing machine and is washed; Further remove impurity, promptly can be used for extracting keratin protein.
Can add 0.1~0.5% sodium hydroxide in the water of described water unhairing machine,, beat wash water and behind quartz sand filtration, can be recycled to remove the lipid impurity in the hair.
The described hair of step (1) cleans and removal of impurities is: when the raw material behaviour of being adopted is sent out; Earlier through removal of impurities, cleaning, branch chi; That isolates longer dimension is used for purposes such as wig manufacturing, and the utility value of remaining size below 20~30mm is lower, can directly be used to extract keratin protein.
The described hair of step (1) cleans and removal of impurities is: when the raw material that is adopted is poultry feather: behind the first dryness in the sun; Economy-combat is loose, selection by winnowing is gone out the bigger sandstone impurity of weight; Beat through the water unhairing machine again and wash, further remove impurity, promptly can be used for extracting keratin protein.
The described hair of step (1) can directly be used to extract keratin protein without removal of impurities for the tankage of woollen mill and mao short flannel that lands.
Alkali lye in the step (2) is prepared by following method: add sodium hydroxide in the water and be mixed with 2.5~5% alkali lye, the sulphite that adds hair dry weight 2~10% again is or/and sulfhydryl compound, and heat temperature raising to 80~98 ℃ get final product.
Described sulphite is any in S-WAT, sodium sulfite anhy 96, potassium sulfite, the Potassium hydrogen sulfite.
Described sulfhydryl compound can be selected any in Thiovanic acid, Thioglycolic acid sodium salt, mercaptoethanol, the halfcystine for use.
The dissolving of hair is in the step (2): the add-on of alkali lye is 5~10 times of hair dry weight, and solution should make temperature remain on 80-85 ℃ after adding, and hair begins dissolving, stirring and dissolving 30~120 minutes after 5-10 minute.
Flocculating aids in said (5) is zeyssatite or perlite, and zeyssatite or the perlite addition in protein soln is 20~150 grams per liters.
Technical scheme of the present invention has also adopted the preparation method of a kind of spinning with hair protein matter solution, may further comprise the steps: (1) hair cleans and removal of impurities; (2) will clean and removal of impurities after hair join in the alkali lye and dissolve; (3) with the Hydrogen chloride of concentration 15~20%, slowly join while stirring in the good hair protein matter solution of step (2) dissolving, be neutralized to pH=7.5~8.5; (4) spinning: the protein liquid after will neutralizing carries out spinning, removes the above solid impurity of 5 μ m, obtains more purified hair protein matter solution; (5) clarification filtration: in the hair protein matter solution that step (4) makes, add flocculating aids, carry out the essence filter, obtain the protein soln of clear; (6) ultrafiltration desalination and filtering micromolecular compound: the ultra-filtration membrane of selecting molecular weight cut-off 3000~10000 for use; Remove salinity and most micromolecular compound more than 90%; Make protein content in solution reach 6~10%, the spinning that is met the requirement of spinning hair-keratin matter conjugated fibre is with hair-keratin matter solution.
Technical scheme of the present invention has also adopted a kind of spinning with the application of hair protein matter solution as spinning protein fibre aspect.
The present invention is that employing waste-low-grade hair is a raw material, through dissolving, purification, processes its keratin protein solution, is used to spin hair-keratin matter conjugated fibre.The hair raw material comprises: extract pig undercoat behind the bristles, people's hair wastes, woollen mill's tankage (land hair), poultry feather etc.; These raw material use propertieies are poor, economic worth is low; The keratin protein solution of processing directly applies to the spinning protein fibre, has excellent development and utilizes prospect.
Adopt method of the present invention, the protein soln after the ultrafiltration can directly be used to spin hair-keratin matter conjugated fibre, has reduced protein dissolving, filtering technological process; Reduced production cost; And because the purification precision is high, can improve stoste stability when being used to spin hair-keratin matter conjugated fibre, reduce filter and spinning jet and change number of times raising stoste utilization ratio; The final yield rate that improves product can obtain better economic benefit.
Method of the present invention is simple and practical, adopts that alkali with low cost dissolves, the method for preparing keratin solution of UF membrane sepn, and the protein soln of processing can directly be used to spin the keratin protein conjugated fibre.Adopting low-grade hair is raw material, with its dissolving and further deep processing and utilization.The hair raw material comprises: extract pig undercoat behind the bristles, people's hair wastes, woollen mill's tankage (land hair), poultry feather etc., these raw material use propertieies are poor, economic worth is low, greatly reduce cost.
