Viscose rayon filment yarn and process for producing same |
摘要 |
A viscose rayon filament yarn excellent in resistance to deterioration with time and uniform in boiling water shrinkage factor in the longitudinal direction of yarn which has been produced by a continuous spinning process characterized by spinning out a viscose having a sulfur content of sulfur oxides and polysulfides of 0.55% by weight or less based on the weight of cellulose, then allowing the yarn to stand for a time period defined by the following equation and then washing it with water and drying it: 7.5DM+15</=Ts</=10DM+25 wherein DM is denier of the monofilament constituting the rayon filament yarn to be spun and Ts, expressed in second, is the standing time of the viscose filament spun.
