Description
Technical field
The present invention relates to a kind of compound viscose staple fibre and manufacture method thereof, especially a kind of feather protein viscose staple fibre and manufacture method thereof belong to the Material Field of textile industry.
Background technology
Silk fabrics is merrily and lightheartedly soft, and gloss is graceful, and good hygroscopicity is comfortable and easy to wear, deeply is subjected to the domestic consumer's of place welcome, but owing to producing the raw material of silk fabrics---the silk shortage, can not satisfy people's needs of life, people then seek a kind of raw material of alternative silk.Once developed regenerated protein abroad, and with milk casein, soybean protein, peanut protein and zein raw material, all because humidity is too low, and eliminated by other fiber, and then developed again the fiber of vinylon and so on, this fibrid intensity is high, but degree comfortable and easy to wear is poor.People attempt again with milk casein and high polymer, and the co-blended spinnings such as, polyvinyl alcohol fine such as propylene are made composite fibre, and this fibre property is better, similar real silk, but the milk casein is expensive, and production cost is high.Therefore be badly in need of developing novel good, the cheap azlon of fibre property that has.
Feather is birds and the cornified derivative of bird epidermal cell, accounts for about 10% of its body weight.According to surveying and determination, the crude protein quality mark of feather keratin is more than 80%, and the amino acid masses mark is more than 70%.One of country that China is in the world herding, poultry farming is maximum, keratin resource is extremely abundant, especially in modern agriculture, large-scale poultry farming has produced a large amount of keratin wastes, wherein feather waste output surpasses 1000kt, except small part as the warming packing material, the overwhelming majority goes out of use and is not fully used, this has not only polluted surrounding environment, but also has wasted a large amount of animal protein resources.
In recent years, the molecular structure owing to the feather keratin uniqueness is found in research, so that the feather keratin material has excellent biological characteristics and good material mechanical performance.Under certain condition with certain density protein hydrolysate stoste and cellulose (viscose glue) stoste, carry out spinning by certain proportioning mixing, and be processed into desirable regenerated protein through post processing, like this in the peptide bond among the protein fibre (-CO-NH-) and the cellulose-OH forms hydrogen bond, produce stronger molecule adhesion, thereby form the composite fibre of novel protein.
The patent No. is that the CN00109055.0(patent name is " production method of regenerated protein stoste, regenerated protein and products thereof ") patent of invention, a kind of preparation method of the feather protein stoste of regenerating is disclosed, and by the mixing weighing spinning of will regenerate feather protein stoste and cellulose stoste, make regeneration feather protein fiber.The disclosed production method of this patent still comes with some shortcomings, and does not consider the set problem of protein, and protein easily comes off from cellulose surface, causes the protein lost in the production process higher.
Summary of the invention
In order to overcome existing silk fabrics silk shortage, the expensive problem of alternative materials, the invention provides a kind of utilization can not spin protein feather regeneration generate albumen stoste and cellulose xanthate solution through static mixing with spin front injection and carry out feather protein viscose staple fibre and the manufacture method thereof that spinning is made.
Not only fibre property is good, cheap for feather protein viscose staple fibre provided by the invention, raw material sources are extensive, also can utilize discarded protein material, is conducive to environmental protection; The viscose staple fibre mesoptile albumen that obtains by feather protein viscose staple fibre manufacture method provided by the invention is good at the anchor effect of cellulose surface, and is beneficial to spinning moulding.
For achieving the above object, the present invention adopts following technical scheme:
A kind of feather protein viscose staple fibre, it is characterized in that: by feather protein liquid and the cellulose sulfonate solution weight ratio by 1-40%:60-99%, obtain through static blend-spinning-solidify-solidify-post processing, this feather protein viscose staple fibre is the loss late of protein＜30% in process of production, finished product is after 50 washings, and its celloglobulin expulsion rate is no more than 5%.
The manufacture method of described feather protein viscose staple fibre is undertaken by following processing step:
The preparation of A feather protein liquid
Solid weight ratio by 1-10:1 takes by weighing feather protein and NaOH, first feather protein is dissolved in temperature and is 40-90 ℃, concentration and be in 0.1-20%(w/w) the sodium hydrate aqueous solution, constant temperature through 30min-8hr stirs, after obtaining feather protein solution, filtration obtains the feather protein liquid after the uniform modification;
B feather protein liquid and cellulose sulfonate solution blending
With feather protein liquid and cellulose sulfonate solution respectively after the deaeration, be that the weight ratio of 1-40%:60-99% is carried out static mixing and carried out making viscose glue after the deaeration by feather protein liquid and cellulose sulfonate solution again;
The C spinning
Viscose glue adopts the two-bath process wet method to carry out spinning, and namely viscose glue is quantitatively sent into for the sebific duct road by measuring pump and entered spinning machine, by candle filter elimination particle impurities again, and sends into spinneret assembly by curved tube, and viscose glue by spinneret orifice, forms the viscose glue thread under pressure;
D solidifies and curing
The viscose glue thread out after, enter coagulating bath, behind coagulation forming, become nascent strand; Nascent strand is sent to boundling stretching in the fixation bath by draw-off godet, when nascent strand stands to stretch, finally finishes the disintegrating and regeneration process, and namely feather protein anchors at cellulose surface, forms the fibre bundle with stable skin-core structure;
