Description
One, technical field
The present invention relates to a kind of spinning solution of novel textile material, especially a kind of is protein and synthetic raw solution of animal hair's protein for spinning regenerated fibres and the production method thereof of polyvinyl alcohol that raw material extracts with the animal fiber.
Two, background technology
Known animal fiber mainly is to be the animal lint of representative with the wool.Animal fiber is that nature offers human extremely valuable material.With fiber condition it is used at present and still occupies main status, because textile technology is limit, often have a large amount of staple fibres to be abandoned, have a large amount of shabby wool fabrics to utilize simultaneously, this is the waste to the limited nature resource undoubtedly.Therefore, how to make these new fibers of animal fiber regeneration that goes out of use, become important research project.
Three, summary of the invention
The present invention's purpose is animal fiber such as the wool that will go out of use in the fabrication processes, cashmere, camel's hair, the rabbit hair, mohair, yak hair and the animal fiber inferior that can not be directly used in weaving processing, particularly shabby fuzz fabric, utilize biochemical technology that it is dissolved, with the polyvinyl alcohol copolymerization, make the protein fibre that spinning solution is spun into various models then.Especially keratin protein is abundant in the animal wool, the cystine height, thus excellent with fibre strength height, good luster, good springiness, the dyeing of this protein synthesis, and process regeneration spinning can spin the short fiber and the long filament of various fiber numbers, improve quality, widened the purposes of animal fiber.
The present invention is achieved in that this invention stoste by animal wool protein 25-40 part, polyvinyl alcohol 70-59 part, and ethanol sodium sulfonate 1-5 part, sodium hydrogensulfite 0.6-1.2 part and adding boric acid are made; Its production method is, sand dust impurity is removed in the shredding of animal lint, wash fat with alkali soap, add (by weight) sodium hydrogensulfite 0.6-1.2 part, with the dissolving of degrease lint, be made for the protein aqueous solution of 14%＜concentration＜15%, add 1-5 part ethanol sodium sulfonate mixing after the insulation reaction, then with the ratio blend copolymerization of polyvinyl alcohol water solution with 30-41: 70-59 of 14%＜concentration＜15% after, add boric acid adjust viscosity get final product spinning solution.
The regenerated fiber that the spinning solution that utilizes the present invention to realize is spun into, its performance still has skin-friendly, hygroscopicity, gas permeability and the good dyeability of animal fine animal fibre, and more former wool fibre has the characteristic that fine density is littler, feel is more soft, wet putting is good.Compare with the milk protein silk on the market, have very strong price advantage; Compare with the phytoprotein silk that has gone on the market, its character is except the advantage with synthetic plant protein filaments, and elasticity, dyeability, hygroscopicity, gas permeability and gloss are better.The raw material sources of developing this product enrich, turn waste into wealth, and have very high economic benefit and social benefit.
Four, the specific embodiment
Describe situation of the present invention in detail below in conjunction with technological process and embodiment.
With the shredding of animal lint, dedusting,, dry stand-by earlier with alkali soap washing unhairing fat.Dissolving method is: will cleaning lint after the degrease impurity elimination, to be immersed in concentration earlier be 1.5-4%, temperature is at 60-75 ℃ of hydrogen peroxide adjuvant water solution, time 40-70 minute, transfer pH value between 9.5-10.5 with sodium hydrate aqueous solution then, slowly be heated to 100 ℃, be incubated 40-90 minute, can obtain the protein adhesive liquid solution, when being cooled to 80 ℃, the sodium hydrogensulfite or the potassium bisulfite that add 0.6-1.2% again, insulation reaction 30-40 minute, add the 1-5 part parent chromophoric monomer ethanol sodium sulfonate of protein wt again, make its copolymerization, copolymerization temperature is 75-90 ℃, and the time is 40-70 minute;
The colloid protein solution that said method dissolving and copolymerization are obtained, after filtration transparent protein adhesive liquid solution.Adding water becomes this solution ratio the protein solution of 14%＜concentration＜15%; Washing requirement and stoste dissolution process and equipment by the vinylon conventional production process, with polyvinyl alcohol dissolving becoming 14%＜concentration＜15% solution, again that above filtration is good protein adhesive liquid solution and poly-vinyl alcohol solution, with (30-41) part ratio blend copolymerization than (70-59) part, and the control pH value is between 6.5-7.3, then, with boric acid or borax solution as macromolecule crosslink agent, and it is even to add in the raw material insulated and stirred in the ratio of the 50-130PPM of stoste gross weight, make its former fluid viscosity be adjusted to the 800-1200 centipoise, be spinnability spinning solution preferably.
Make after the above stoste, select the spinning technique and the equipment of mature soylon wet method staple fibre for use, with the stoste spinning and to be processed as finished product one be hair protein (or keratin protein) regeneration synthetic fiber.Or its stoste is spun into the protein long filament of various fiber numbers with special-purpose continuous yarn spinning equipment.
The consisting of of various compositions in this spinning solution: animal wool protein accounts for 25-40 part, and polyvinyl alcohol accounts for 70-59 part, and close chromophoric monomer ethanol sodium sulfonate accounts for 5-1 part, and auxiliary material comprise sodium hydrogensulfite or potassium bisulfite 0.6-1.2 part.
