ABSTRACT:
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 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:
