Abstract
Partial dissolution of cellulose by ferric sodium tartrate complex (FeTNa) solution was examined as refining treatment of the organic-solvent spun cellulosic fiber (Tencel). The physical properties, the imbibition of water and the dyeing properties were investigated. As a result of the treatment, the crystallinity and dyeing rate of Tencel fiber were increased. Elastic modulus of the treated yarn was increased because of shrinkage of the original Tencel yarn. The fabric sample knitted with treated yarns showed the improved fibrillation resistance.
