Abstract
The invention provides a rabbit hair fiber processing method. The rabbit hair fiber processing method has the advantages that rabbit hair fibers are dyed after oxidation treatment, enzyme treatment and reduction treatment, so that the rabbit hair fibers are bright in color and luster, clear in grain, soft in hand feeling, high in elasticity, free from hair shedding and machine washable, cleaning and flattening effects on the rabbit hair fibers are achieved, intertwining of the rabbit hair fibers during spinning is reduced, high durability is achieved, and the rabbit hair fibers do not fade and discolor during long-term use.
Description
Technical field
The present invention relates to the technical field of rabbit hair processing, particularly relate to a kind of processing method of Pili in Fetus of Haired Rabbit rabbit fur fibre.
Background technology
Along with China's economy constantly develops and the improving constantly of personal consumption ability, the people to the requirement of haberdashery towards future developments such as " light, soft, warm, beautiful, dry and comfortable ", rabbit hair clothing item has then all possessed above-mentioned advantage, and the advantage of the rabbit hair is then cotton, chemical fibre and other animal hairs are incomparable.Especially the rabbit hair of Pili in Fetus of Haired Rabbit is not only also thin than the thinnest wool, the clothes that the Pili in Fetus of Haired Rabbit rabbit hair makes, strong, the frivolous softness of wettability power, elegant in appearance.
The Pili in Fetus of Haired Rabbit kind of China, German Angola Pili in Fetus of Haired Rabbit, genealogy of law Angola Pili in Fetus of Haired Rabbit, the Japanese Angola Pili in Fetus of Haired Rabbit introduced the eighties in last century the earliest, biotechnology through multi items is hybridized, the improvement of traversed by, formed characteristic in be Pili in Fetus of Haired Rabbit, single become mildewed rabbit year wool product of only growing up exceedes external kind, reaches between 1.5 kilograms to 2.5 kilograms.
The rabbit hair of Pili in Fetus of Haired Rabbit forms primarily of keratoprotein, does not have that the rabbit hair of treated Pili in Fetus of Haired Rabbit can not be exposed to the sun by high temperature, the sun, moth attacks.Rabbit fur fibre has three layers, bosom be medullary substance layer, form porous organization by the withered cell being full of air, its outer second layer is cortical layer, is made up of fusoid horn cell, this is the major part determining rabbit hair quality, outmost third layer is scale layer, arranges horn cell closely and forms, smooth surface by one deck as scale, reflective power is strong, and the rabbit hair is seemed, and gloss is stronger.
The rabbit hair is a kind of senior wool textile raw material, because the medullary substance layer of the rabbit hair is flourishing, fiber is light and warmth retention property is large, fibre weight in unit are is more, thermal property compares cotton, wool is all good, but rabbit hair intensity is not as good as wool and cotton, its fiber is soft, be applicable to slubbing, spinning, also can be used for knitting, weaving, with wool, nylon, terylene etc. blending can become the rabbit hair yarn of different size, and the grease of the rabbit hair is few, generally do not need to carry out degreasing scouring of wool, can directly weave, in addition find through research, rabbit hair feltability is large, stir easy entanglement more, as through degreasing scouring of wool, easy entanglement, add the difficulty of weaving.
The fine, soft fur of the rabbit hair and rabbit suede, natural torsion, can uphold, and rabbit hair intensity is also known as pulling force, and without the rabbit hair of pulling force, its fiber damaged, can not as textile raw material, if the rabbit hair makes moist, by the vexed embrittlement that also can go bad without pulling force simultaneously.Because the scale structure on rabbit hair surface is different from wool, its smooth surface, rub little, between fiber, cohesive force is poor, when fabric cleans, easily falls hair, is the technology barrier hindering high-grade rabbit hair fabric.
CN1032374A discloses and adopts radio isotope cobalt-60, and high-pressure electronic bundle and neutron beam etc., carry out radiation treatment to the rabbit hair, make rabbit hair rough surface.But need special device in this kind of method production process, as more than 100,000 electron volts high pressure or adopt radioactive material, have hidden danger for safety in production, this kind of method is less on fibre strength impact, is only only applicable to the fiber surface etching of disperseing simultaneously.
CN101748600A discloses and rabbit fur fibre DCCNa is carried out chemical treatment, although this kind of method improves the spinnability of rabbit fur fibre, but due in chemical treating process, destroy the integrality of rabbit fur fibre surface scale, cause rabbit fur fibre easily to rupture.
CN103046330A discloses a kind of method of rabbit hair fibre modification process of having dyeed, by operation process such as reduction, oxidation, polymerization weightening finish, antistatic and soft treatment, by taking apart and the structural disulfide bond of rabbit fur fibre of recombinating, strengthen the covalent bond between the flexibility of yarn and fiber molecule, utilize the adhesion between polymer increase rabbit fur fibre, re-use softener and make the rabbit hair possess soft feel.But because the rabbit fur fibre of dyeing is carried out reprocessing by it, make the rabbit hair color and luster after processing dull, not nature.
Method in above-mentioned patent, the problem solving rabbit fur fibre cohesive force difference achieves must effect, but or cannot apply in actual production, or cause rabbit fur fibre easily to rupture, or reduce natural colored and the feel of rabbit hair products.Therefore be necessary that research is with the processing technology improving rabbit fur fibre further.
Summary of the invention
Not enough for prior art, the invention provides a kind of processing method of rabbit fur fibre, by method provided by the invention, the quality color and luster after the processing of the rabbit hair can be significantly improved, and spinnability is protected.
To achieve the above object of the invention, the present invention includes following technical scheme:
