Description
Technical field
The present invention relates to a kind of protein-modified chemical fibre and production method thereof of utilizing poultry feather to make.
Background technology
Yan Zhi azlon is that the protein lysate that extracts from natural animal cow's milk or plant (as peanut, corn, soybean etc.) forms through spinning traditionally, the research history of azlon early, abroad just begin one's study about the late nineteenth and early twentieth centuries greatly, as 1894, in gelatin solution, add formaldehyde and carry out spinning, make gelatin fiber; 1904, Todten Haupt used the casein that refines from cow's milk to carry out spinning, makes casein fibre; Nineteen thirty-five, Ferretti further studies casein fibre, and Italian SNIA company has developed casein fibre; 1938, Britain ICI company made ground nut fiber, and trade name is Atdil, and this fiber water absorption rate is about 14%, and fracture strength is 0.8g/d; 1938, it was the fiber of raw material that Nof Corp. has developed with the soybean; Nineteen thirty-nine, the protein that Corn product Refining company will refine from corn is with alcohol or alkali dissolution spinning and make Zein fibers, and commodity are called VicaraArdilin Fiber, and this fiber proportion is 1.25g/cm
3, water absorption rate is about 10%, fracture strength is 1.06～1.32N/dtex.Early 1940s, the U.S., Britain have developed casein fibre, and commodity are called Aralia (U.S.), and Fibralane (English), proportion are 1.9g/cm
3, water absorption rate is 14%, and fracture strength is 0.704～0.88N/dtex, and ductility is 15%, and resistance to water is bad; 1945, the U.S., Japanology soybean fiber, american goods is called Soylon, water absorption rate is 11%; 1948, U.S. Varginia Carol Chenical company developed Zein fibers Vic-ara; 1969, Tsuruga factory of Japanese Japan company began the development and production milk protein fiber, was named as Chinon (city name of the France of getting), and it is reacted by milk protein and acrylonitrile graft copolymer and makes.
Owing to be subjected to the restriction of early stage scientific and technological level, the azlon of above-mentioned development is low because of brute force, fiber thick, poor, the no taking of physical and mechanical property is worth, the difficulty of manufacturing is big etc., and various reasons fails to realize suitability for industrialized production.Afterwards owing to the reasons such as development of petrochemical industry, the researcher turns on the research direction of new fiber the development of synthetic fiber and regenerated celulose fibre, greatly about the forties in 20th century to successfully developing chemical fibres such as viscose glue, polyamide fibre, terylene, acrylic fibers, spandex between the fifties in succession, and realized suitability for industrialized production.In the age that became a large amount of development of chemical fibre in 50 years subsequently, many clothes, decorating cloth, industrial cloth have substituted the part natural fabric.Though synthetic fiber have many premium properties, also exist hygroscopicity and gas permeability poor, wear shortcomings such as uncomfortable.Because the modern trends towards naturalization to the pursuit of clothes, comfortableization, leisureization, variation, natural fabric has been subjected to people more and more to be favored.But natural fabric middle cotton, fiber crops, wool, silk etc. have been subjected to the restriction of plantation, cultured area, can't develop in a large number.Therefore, since the nineties in 20th century, the development work to azlon begins again to pay attention to both at home and abroad.
In recent years, it is the azlon " chinon " of raw material and acrylonitrile graft copolymer that Japanese Japan spins that company develops again with New Zealand's milk, and it is unique in the world at present suitability for industrialized production casein fiber of having realized.It has gloss and soft feel as the natural silk, and hygroscopicity and wet transmitting performance are preferably arranged, and fabulous heat insulating ability is comfortable and easy to wear, but fiber itself is faint yellow, and poor heat resistance in xeothermic easily yellowing more than 120 ℃, therefore still can't large-scale popularization be used so far.In addition, Japan approximately from during the World War II to postwar a period of time, the research of also once carrying out utilizing the protein of fish to make regenerated fiber.
China once carried out preliminary exploration to azlon respectively in the 1950's, the seventies, but did not succeed.The nineties, Sichuan Province once developed the silkworm chrysalis regenerated protein, though fiber has been realized small lot batch manufacture, low percentages of protein, and weave and print and dye processing in have a lot of problems, had a strong impact on such Products Development and technology popularization.Donghua University, Kingsoft petrochemical industry were once carried out research to the spinning of casein/propylene ester graft copolymer, but also stayed in theoretic discussion, did not see its product; Fudan University and Donghua University once carried out research to the spinning of regenerated silk solution, also failed to realize suitability for industrialized production.
Early 1990s, Henan Hua Kang Biochemical Engineering associating group company begins soybean protein fibre is goed deep into the systematic research exploitation, and through the research of more than ten years, examination is spun into merit in March, 2000, has carried out industrial test in the world first.Article one industrial test production line yearly productive capacity is 1500 tons at present, and the fiber single fiber fineness of being produced was 1.1 and 1.5 dawn, and cutting into staple length is 38mm, 51mm, 76mm.This fiber is compared with the azlon of domestic and international exploitation, has higher strength and other premium properties.
Down fiber (containing duck's down, goose down and chicken feather etc.) the same with natural protein fibres such as wool, silks main be the big molecular composition that forms by the several amino acids condensation.It is the main body that constitutes fiber, also is the base substance of decision fibre chemistry character.Thereby wool often is referred to as the angle protein, and silk is referred to as fibroin, and eider down is referred to as the plumage protein again.Because these protein macromolecule interchains exist disulfide bond, salt type bond, hydrogen bond etc., make big molecule have special network structure, their chemical property is generally comparatively stable.Down fiber and wool surface structure different significantly be that it does not have scale layer, and fiber is short, every plumage filament length degree is generally 1～3cm, existing with a suede form is to grow many tiny plumage silks in the every principal fiber, and the tiny plumage silk of each root becomes the principal fiber of another unit, so form elegant and unique down fiber repeatedly, in each suede piece, comprising tens essentially identical fibers of internal structure, therefore all can produce certain repulsion and make it apart from keeping maximum between every fiber, this just makes eider down produce bulkiness.
The awkward water-soluble sterol of the outermost layer of down fiber and the bilayer cell membrane of triguaiacyl phosphate formation, this layer bimolecular film accounts for about 10% of whole down fiber weight, and inner slit and cavity are more, cause the proportion of eider down light especially, its critical surface tension is minimum in all proteins fiber, so the water resistance spy of down fiber is good, clean eider down can not be soaked into by pure water under the normal temperature.In addition, do not cause the down fiber smooth surface owing to down fiber has the phosphorus sheet, its coefficient of friction is littler than wool, silk, and fiber is short, all spinning has brought certain degree of difficulty to down fiber for these, so there is not eider down directly to be used to the report that spins up to now.
Therefore contain a large amount of alkaline side group and acidic pendant groups in the eider down molecular structure, have the amphotericity that not only is acid but also is alkalescence.Aspect physicochemical property, down fiber is heated and can not be melted and decomposes.Eider down dewaters in the time of 115 ℃, begins in the time of 150 ℃ to decompose, and disulfide bonds in the time of 200～250 ℃, 310 ℃ of beginning charings, 720 ℃ take fire, and its combustibility is lower than cellulose fibre.In the plumage protein molecule-CONH one key is relatively more responsive to dayligth effect.It is very unstable to seem under the effect of daylight middle-ultraviolet lamp.Generally speaking, eider down is better to the stability of daylight, approaches wool.The acidproof ability of eider down is stronger.
Though down fiber is quite similar with the structure and the performance of fibers such as typical wool, silk, and its special warmth retention property, water proofing property, wrinkle resistance and characteristics such as gentle, sliding, light are arranged again, but owing to be subjected to placing restrictions on of aspects such as economy, technology, eider down often only is used as the filler of clothes and bedding, up to now, be not applied to textile industry as yet as textile material.
Along with the continuous development of China's animal husbandry, discarded poultry feather get more and more.According to the preliminary statistics, the poultry feather of China is annual to be produced more than 200,000 tons, and collect utilize less than 100,000 tons, and not by processing and utilization reasonably.Poultry feather is wasted as abundant protein resource, also causes environmental pollution simultaneously.Aspect the regeneration of down fiber, have only the U.S. and the Japanese work of having carried out this respect, particularly Japan owing to the shortage of natural resources, walk prostatitis in many aspects in the world at the regeneration aspect aspect the high-quality inartificial nature.
