Abstract (en)

Improvement of specular gloss of viscose fiber using nanocrystalline cellulose The invention relates to a process for imparting gloss onto the surface of a viscose fiber material, characterized in that (v) a viscose fiber material is immersed in a liquid hydrophilic medium to give a swollen viscose fiber material, (vi) said swollen viscose fiber material is treated with a suspension or solution of nanocrystalline cellulose in a liquid hydrophilic medium, (vii) said treated viscose fiber material is washed with water and optionally with aqueous sulfuric acid, (viii) said washed viscose fiber material is dried.
