Abstract

The invention discloses a composite cellulose viscose filament made by mixing wood and bamboo to make composite cellulose new pulp as raw material and a preparation method thereof. The raw material pulp is wood and bamboo raw materials according to the following weights The composite cellulose pulp prepared by proportioning and combining: wood: bamboo = 1% to 99%: 1% to 99%; the preparation method includes the following process steps: dipping, pressing, pulverizing, yellowing, dissolving, grinding, filtering , defoaming, spinning, refining and drying; the invention expands the raw material source of viscose fiber, and solves the problems of low production efficiency and high cost; the composite fiber obtained by spinning has bright luster and excellent natural coloring. It is a pure natural green environmental protection product, and has unique antibacterial and antibacterial properties that are not found in pure cotton pulp, wood pulp and hemp pulp viscose fibers. The anti-odor function and texture of bacteria can also overcome the problems of low strength and whiteness of bamboo viscose fiber alone, and the raw materials are easily available, the production process is optimized, the efficiency is high, and the advantages of various natural cellulose can be integrated 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 wood pulp or wood pulp or bamboo pulp as a single raw material. A regenerated cellulose fiber made from silk, refining, drying and barreling 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 compoundi...
