Patent

CA 2470052

Embodiments of the invention provide a method for manufacturing woven or knit fabrics with improved shrink and crease resistance and good shape memory after repeated washing. The method comprises (a) contacting an enzyme treatment composition with a cellulosic material (e.g., cotton fabric), the enzyme composition comprising an enzyme; and (b) treating the cellulosic material with a polymeric resin composition. Embodiments of the invention also provide a fabric manufactured by sequentially treating the fabric with an enzyme composition and a resin treatment agent.

Dans des modes de réalisation, l'invention concerne un procédé de fabrication de tissus tissés ou de tricots faisant preuve d'une meilleure résistance au rétrécissement et aux plis et d'une bonne mémoire de forme après des lavages répétés. Le procédé consiste à (a) mettre en contact une composition de traitement enzymatique avec une matière cellulosique (p.ex. tissu en coton), la composition enzymatique comprenant une enzyme ; et (b) traiter la matière cellulosique avec une composition de résine polymère. Dans d'autres modes de réalisation, l'invention concerne également un tissu fabriqué par traitement séquentiel de tissu avec une composition enzymatique et un agent de traitement de résine.
