Abstract
Processes for manufacturing high-tenacity and high-grade rayon filament fibers and filaments, with an average conditioned toughness of approximately 3 to 4 g/d, a wet modulus of approximately 0.4 to 0.6 g/d. D a wet toughness of about 2 to 3 g/d, a conditioned elongation of about 10 to 15 percent, a wet elongation of about 12 to 18 percent, and a crimping greater than about 12 curled per centimeter, which comprises the preparation of a modified viscose spinning solution containing a blend of viscose modifiers that substantially retard regeneration, said modified viscose solution having a saline (nacl) index comprised between about 2.5 and 6, said modified viscose solution being spun at a temperature of about 35º to 45ºC in a spinning bath of the coagulation type, said spinning bath containing the type of coagulation from 4 to 6 percent by weight of sulfuric acid.
