| titleOfInvention | PROCEDURE FOR THE PREPARATION OF RECYCLED CELLULOSE FIBERS OF VISCOSA |
| abstract | Process for the preparation of viscose regenerated cellulose fibers comprising preparing alkaline cellulose xanthate with a relatively high degree of polymerization and with uniform distribution of the polymerization, adding and dissolving therein 0.15-0.3% (from the viscose) of an alkylene oxide polymer, or an adduct of an amine and an alkylene oxide or an acid amide to make viscose, spin said viscose in a spin bath containing 0.005-0.3% of a divalent metal salt , and tensioning the resultant filaments, which have a regeneration value of 40-60%, in a second bath having a temperature of at least 80ยบ C and a sulfuric acid concentration of not more than 1.5%.
