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 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 compoun...
