Description
Technical field
The present invention relates to a kind of viscose rayon and preparation method thereof, particularly relate to a kind of Pearl anti-ultraviolet fiber and preparation method thereof.
Background technology
Viscose rayon (viscosefibre), is viscous fine full name. It is divided into again viscose filament yarn and short rayon fiber. The cellulose fibre that viscous fibre is is raw material production with cotton or other natural fiber. In 12 kinds of main textile fabrics, viscous fine moisture percentage meets the physiological requirement of human body skin most, has the characteristics such as smooth nice and cool, ventilative, antistatic, dyeing is gorgeous.
Viscose rayon belongs to regenerated celulose fibre. It is with native cellulose for raw material, makes soluble cellulose sulphonic acid ester through operations such as alkalization, aging, sulfonation, is re-dissolved in sig water and makes viscose glue, make through wet spinning. Adopt different raw materials and spinning technique, it is possible to respectively obtain common viscose fiber, koplon and high tenacity staple fibre etc. Common viscose fiber has general physical and mechanical properties and chemical property, divides again cotton, wool type and long filament type, is commonly called as synthetic cotton, man-made hair and artificial silk.
Viscous fibre is one of ancient fiber species. 1891, Kroes, Buddhist script written on pattra leaves and be first made for sodium cellulose xanghate solution with cotton for raw material than Dare, owing to the viscosity of this solution is very big, thus name " viscose glue ". After acid met by viscose glue, cellulose precipitates out again. According to this principle, within 1893, developing into a kind of method manufacturing cellulose fibre, this fiber is just called " viscose rayon ". By 1905, Miller that etc. invented dilute sulfuric acid and the coagulating bath of sulfate composition, it is achieved that the industrialized production of viscose rayon.
The basic composition of viscose rayon is cellulose. The cross section indention skin-core structure of common viscose fiber, longitudinally straight have ditch horizontal. And rich fine without skin-core structure, cross section is rounded.
Viscose rayon has good hygroscopicity, and when general atmosphere, regain is about 13%. Significantly expanding after moisture absorption, diameter increases up to 50%, so after water, feel is hardened under fabric, shrinkage factor is big. The fracture strength of common viscose fiber is less than cotton, is about 1.6～2.7cN/dtex; Elongation at break, more than cotton, is 16%～22%; Wet strong declining many, be about dry strong by 50%, hygrometric state elongation increases about 50%.
The chemical composition of viscose rayon is similar to cotton, thus more alkaline-resisting and not acidproof, but all more cotton difference of alkaline-resisting acid resistance. In addition the thermal property of viscose rayon is also similar to cotton, and density is 1.50～1.52g/cm close to cotton3. The hydroxyl of cellulosic macromole is prone to multiple chemical reaction, therefore, can pass through the methods such as grafting, viscose rayon is modified, improve viscose rayon performance, and produce the fiber of various specific use.
But, existing viscose rayon, due to function singleness, is not increasingly approved by market. Therefore, urgently it is desirable to develop high performance industry function viscose fiber, promotes the surcharge of viscose rayon, to meet the needs of people's increasingly diversification.
