Described regenerated celulose fibre, including CUP, chitin fiber, bamboo fibre, Modal fiber, Tencel fiber etc.
In a word, all fibers again recycled for raw material with cellulose all can be referred to as regenerated celulose fibre. The development of regenerated celulose fibre can be divided into three phases generally, defines three generation products. The first generation was 20 beginnings of the century is solve the common viscose fiber that shortage of cotton emerges. The second filial generation is to start to realize the koplon of industrialized production the 1950's, the Modal fiber of production that its major product includes the toramomen (rear called after Polynosic) of Japan's research and development and the change type high-wet-modulus fibre HWM of American R & D and Lenzin company adopts new technology in the later stage eighties. In the later stage sixties, owing to closing developing rapidly of fine production technology, sufficient raw and with low cost, synthetic fibers have greatly impacted the market position of regenerated celulose fibre. Many research institutions and enterprise have increasingly focused on the development and application of shin-gosen. During this period, the development of world's regenerated celulose fibre tends to stagnating. Third generation product is with the short fine Tencel (tencel) of the release nineties in 20th century, long filament Newcell for representative. Realized, advocate the impact of the factors such as nature by health environment-friendly, regenerated celulose fibre has been had new understanding by people, the physicochemical property of a new generation's regenerated celulose fibre there has also been and is sufficiently improved, and therefore, the application of regenerated celulose fibre has reappeared swift and violent growth.
Tencel fiber is also known as " tencel ", also known as " Lyocell (lyocell) ". It is the wood pulp based on coniferous tree, water and solvent NMMO (4-methyhnorpholine-N-oxide) mixing, heating is to being completely dissolved, will not producing any derivant and chemical action, the direct fabrics through remove impurity in course of dissolution, its molecular structure is simple carbohydrate. Tencel fiber can decompose completely in earth, environmentally safe;It addition, the amine oxide solvent that uses is completely harmless to human body in producing, be almost entirely capable of reclaiming, can Reusability, produce the cellulosic molecule contained by Raw pulp and do not play chemical change, no coupling product, outside without garbage discharge factory, is environmental protection or green fiber. This fabric has good hygroscopicity, comfortableness, drapability and stiffness and dyeability is good, in addition again can with cotton, hair, fiber crops, nitrile, the blending such as wash, it is possible to RING SPINNING, air spinning, cored are spun, and are spun into various cotton and wool type yarn, covering yarn etc. Therefore this fiber can not only apply in the fabric production of underwear, and the fabric for coat ready-made clothes uses also very extensive.
Modal fiber, also known as weaving cellulose modal, Modal fibre, is a kind of brand-new cellulose fibre, and the raw material of Modal fiber comes from the timber of the Nature, can natural degradation after using. Owing to this fibrid is that to adopt native cellulose be raw material, there is biological degradability, and in fiber production process, do not produce the serious environment pollution problem of similar viscose rayon, be the novel environment-friendlyfiber fiber of 21 century. Modal fiber price is the half of Tencel fiber, is second filial generation regenerated celulose fibre. Modal fiber with multiple fiber blend, intertexture, can play the feature of respective fiber, reach effect more preferably. Modal fabric lining moisture pick-up properties, permeability are better than pure cotton fabric, and it is soft, and drapability is good, comfortable and easy to wear, bright in color, are a kind of natural mercerising fabrics. Just because of modal fabric is comfortable, good springiness, the characteristics such as breathability is good, it has been used in underwear production by much well-known underwear brand as seven wolves, fibril bird, top-notch player, next, the Davidarchy of Fu Ni etc., also has increasing domestic consumer to like Modal underwear. But also because these characteristics, it is less that modal fabric is used in ready-made clothes, because it is relatively inaccessible to the effect that sizing is moulding.
Bamboo fibre is the New Regenerated Cellulosic Fibers of the development of China's self-developing industrialization after soybean fiber, and bamboo fibre divides bamboo cellulose fiber and bamboo fiber. Bamboo cellulose fiber is with Phyllostachys pubescens Mazei ex H.de Lebaie for raw material, adds functional aid, process through wet spinning in bamboo pulp. Bamboo fiber is the fiber produced after natural biological preparation processes by Phyllostachys pubescens Mazei ex H.de Lebaie. As the bamboo pulp of spinning material, deriving from the fresh bamboo of short-term training, resource is very abundant. Its garbage soil buries, burn and do not result in environmental pollution, belongs to environmental protection fiber, meets the demand of green consumption. It is similar with viscose rayon that bamboo fibre is performance, and bamboo fiber has good moisture absorption, breathability, and its drapability and dyeability are also relatively good, have the gloss as silkworm silk and feel, and have antibacterial, deodorant, anti-ultraviolet function. These natural characteristics of bamboo fibre make its exclusive seat in the weaving of underclothes fabric. Along with the partially healthy naturalization of consumer spending idea, bamboo fibre receives pursuing of Ge great underwear production firm.
Chitin is widely present in the arthropodan shells such as the aquatic products such as shrimp, Trionyx sinensis Wiegmann and insecticide, exists in the cell wall of mushroom, algae. Viscose chitin fibre is to mix, with chitin, chitosan, the fiber made by conventional wet spinning process with cellulose. It has biological activity, biological degradability and biocompatibility, has excellent moisture-absorbing moisture-keeping function. Adopt chitin fiber to take the function of deodorization with cotton blended fabric, in clothes decoration application and development, have vast potential for future development.
CUP is a kind of regenerated celulose fibre, it is to be dissolved in the liquor ammoniae fortis of Copper hydrate or alkaline cupric salt by natural cellulosic feedstocks such as cotton linters, it is made into spinning liquid, in coagulating bath, CUP element molecular chemistry thing disintegrating and regeneration goes out cellulose, and namely the hydrate cellulose of generation obtains CUP through post-treatment. The cross section of CUP is rounded, and without skin-core structure, fiber can bear high elongation, and prepared monofilament is relatively thin, so fabric is soft, gloss is soft, has silky touch. The hygroscopicity of CUP is close with viscose fiber, and its official regain is 11%, and when general atmosphere, regain can reach 12%--13%, and under identical dyeing condition, the dyeing affinity of CUP is big compared with viscose fiber, paints deeper. The dry strong and viscose fiber of CUP is close, but wet is higher than by force viscose fiber, and wearability is also superior to viscose rayon. Owing to fiber is soft, gloss is suitable for, and commonly uses and makees high-grade silk weaving or knitted fabric. Its wearability is more excellent, good hygroscopicity, great pendency sense, and wearability is similar to silk, meets environmental protection dress ornament trend.
