The invention discloses a production technology of a continuously spun
viscose fiber with a special-shaped cross section. The production technology comprises the specific processes that a
viscose stock solution is sprayed into an acid bath through a
spinning jet for a reaction to generate as-spun filaments, the concentration of
sulfuric acid in the acid bath is 120-160 g / L, the concentration of
sodium sulfate is 200-270 g / L, the concentration of an auxiliary agent
polyethylene glycol
polyamine BEROL SPIN 652 is 10-200 ppm, the temperature of the acid bath is 47-60 DEG C, the as-spun filamentsare formed in a
glass tube, is subjected to stretch forming at a
spinning speed of 80-170 m / min, and then is wound into a reel through a winding
system, and finally, the continuously spun
viscose fiber with a star-shaped cross section is obtained. The production technology of the continuously spun
viscose fiber with the special-shaped cross section has the advantages that a new technology for continuously
spinning zinc-free fibers through viscose is adopted, the technology is simple, the cost is low, the
pollution to a
water body caused by the
discharge of
zinc sulfate along with
wastewater iseffectively avoided, the
environmental protection effect is better, in addition, the prepared product has a larger specific surface area and also has functions of flatness and smoothness,
moisture absorption, breathability, sweat
discharge and the like, and the market prospect is wide.
