Abstract
An improved viscose rayon fiber is disclosed having a degree of polymerization of greater than about 500 and an alkali solubility of below about 7.5%, the fiber also exhibits a tenacity of about 5-6 grams per denier and a conditional elongation of between about 10-20%. This fiber exhibits increased toughness and increased wet strength when compared with prior art rayon fibers.
