Abstract

This invention relates to a type of compound cellulose mucilage filament and its process. The compound cellulose is arbitrarily made up by two or more native materials of follows: cotton flock, wood,flax, bamboo, straw and crust as material. The process includes follow technologies: dipping, expression, size reduction, triolation, dissolving, filtration, spinning, refining and drying. This invention expands the source of native material, solve the problem of high cost and low efficiency. It also solve the problem of low strength and whiteness when singly use bamboo viscose fiber.

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 uses cotton pulp or wood pulp or bamboo pulp as a single raw material, after impregnation, pressing, crushing, yellowing, dissolving, grinding, filtering, degassing, spinning, refining, drying 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...
