Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of high-performance viscose filament fiber and its preparation method which is produced with composite cellulose pulp as raw material. The new type of pulp is used as raw material, which expands the raw material source of viscose fiber and solves the problems of low production efficiency and high cost
Cotton, linen and bamboo composite fibers produced by spinning are bright in luster, have natural and excellent coloring properties, rebound properties, moisture absorption and release properties, and air permeability are even better than various synthetic fibers. It is a pure natural green environmental protection product. At the same time, it has unique antibacterial, antibacterial and deodorizing functions and textures that are not found in the use of cotton pulp, hemp pulp, bamboo pulp, and viscosity fibers. It can also overcome the problems of low strength and whiteness of bamboo viscose fibers alone, and the raw materials are easy to obtain. Production Process optimization, high efficiency, low cost, can combine the advantages of various natural cellulose according to needs

Description

Technical field: [0001] The invention relates to a viscose filament and a preparation method thereof, in particular to a composite cellulose viscose filament produced by using composite cellulose pulp as one of the raw materials and a preparation method thereof. Background technique: [0002] At present, viscose fiber is made of cotton pulp or wood pulp or bamboo pulp as a single raw material. A regenerated cellulose fiber made by other processes. Fabrics made from natural fibers have good hygroscopicity, dyeability and antistatic properties. With the improvement of people's living standards, the requirements for fabrics are getting higher and higher, not only the pursuit of comfort, but also more emphasis on environmental protection, antibacterial and antibacterial properties, etc. The existing composite viscose fibers are all produced on the spinning machine For example, the semi-continuous centrifugal spinning machine is used for compounding instead of directly compound...
