Composite cellulose viscose filament yarn with composite cellulose pulp as raw materials made of cotton, hemp and bamboo mixture and preparation method thereof

Abstract

The invention discloses a composite cellulose viscose filament made of cotton, hemp and bamboo mixed to make composite cellulose new-type pulp as a raw material and a preparation method thereof. The raw material pulp of the composite cellulose viscose filament is Composite cellulose pulp made of cotton, hemp and bamboo raw materials combined according to the following weight ratio: cotton: hemp: bamboo = 1% to 99%: 1% to 99%: 1% to 99%; A preparation method of a composite cellulose viscose filament comprises the following process steps: dipping, pressing, pulverizing, yellowing, dissolving, filtering, defoaming, spinning, refining, drying; the present invention expands the raw material source of viscose fiber , which solves the problems of low production efficiency and high cost; the composite fiber obtained by spinning is bright in luster, has natural and excellent coloring properties, resilience, moisture absorption and release, and air permeability are even better than various synthetic fibers. It is a pure natural green environmental protection product, and it has unique antibacterial, antibacterial and deodorizing functions and texture that are not available in pure cotton pulp, wood pulp, and hemp pulp viscose 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, the production process is optimized, the efficiency is high, and the advantages of various natural celluloses can be integrated according to the 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...

AI Technical Summary

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
