Description
Technical field
The present invention relates to a kind of viscose and preparation method thereof, relate in particular to a kind of pearl ultraviolet prevention fiber and preparation method thereof.
Background technology
Viscose (viscose fibre) is sticking fine full name.It is divided into again viscose filament yarn and short rayon fiber.Sticking fibre is take cellulose fibre cotton or that other natural fabric is produced as raw material.In 12 kinds of main textile fabrics, sticking fine moisture percentage meets the physiological requirement of human body skin most, have smooth nice and cool, ventilative, antistatic, the characteristic such as gorgeous dyes.
Viscose belongs to regenerated celulose fibre.It is take native cellulose as raw material, makes the soluble cellulose sulphonic acid ester through operations such as alkalization, aging, sulfonation, is dissolved in sig water to make viscose glue again, makes through wet spinning.Adopt different raw material and spinning technique, can obtain respectively 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 type, wool type and long filament type, is commonly called as artificial cotton, artificial wool and artificial silk.
Sticking fibre is one of ancient fiber species.1891, Kroes, Buddhist script written on pattra leaves and at first made sodium cellulose xanghate solution take cotton as raw material than Dare, because the viscosity of this solution is very large, thereby name " viscose glue ".After viscose glue was met acid, cellulose was separated out again.According to this principle, developed into a kind of method of making cellulose fibre in 1893, this fiber just is called " viscose ".By 1905, you waited the coagulating bath of having invented dilute sulfuric acid and sulfate composition Miller, had realized the suitability for industrialized production of viscose.
The basic composition of viscose is cellulose.The cross section indention skin-core structure of common viscose fiber, vertically straight have ditch horizontal.And rich fine without skin-core structure, the cross section is rounded.
Viscose has good hygroscopicity, and under the general atmosphere condition, regain is about 13%.Significantly expand after the moisture absorption, the diameter increase can reach 50%, thus under the fabric behind the water feel harden, shrinkage factor is large.The fracture strength of common viscose fiber is less than cotton, is about 1.6～2.7cN/dtex; Elongation at break is 16%～22% greater than cotton; Wet strong descend manyly, be about and do by force by 50%, the hygrometric state elongation increases about 50%.
The chemical composition of viscose is similar to cotton, thus more alkaline-resisting and not acidproof, but alkaline-resisting acid resistance is all cotton poor.The thermal property of viscose is also similar to cotton in addition, and density is 1.50～1.52g/cm near cotton
3Cellulosic macromolecular hydroxyl is easy to occur the number of chemical reaction, therefore, can carry out modification to viscose by methods such as grafting, improves the viscose performance, and produces the fiber of various specific uses.
Yet existing viscose is not more and more approved by market owing to function singleness.Therefore, urgent expectation can be developed high performance industry function viscose fiber, promotes the surcharge of viscose, to satisfy the needs of the more and more polynary change of people.
