Method for producing cellulose/cellulose triacetate fabrics

Abstract

Disclosed is a method for producing cellulose/cellulose triacetate fabrics. The method is characterized by the alkali treatment of a conjugated fabric comprising cellulose diacetate fibers with a degree of substitution of 2.0 to 2.75 and cellulose triacetate fibers with a degree of substitution of 2.75 or higher to convert the cellulose diacetate fibers into cellulose fibers.

What is claimed is:  
     
         1 . A method for producing a cellulose/cellulose triacetate fabric, wherein a conjugated fabric comprising cellulose diacetate fibers with a degree of substitution of 2.0 to 2.75 and cellulose triacetate fibers with a degree of substitution of 2.75 or higher is treated with alkali to convert the cellulose diacetate to cellulose.  
     
     
         2 . The method as set forth in  claim 1 , wherein the conjugated fabric is treated with strong alkali, or a combination of strong alkali and weak alkali in one bath or two baths.  
     
     
         3 . The method as set forth in  claim 2 , wherein the alkali is added in combination with a saponifying promoter.  
     
     
         4 . The method as set forth in any one of  claims 1  to  3 , wherein the conjugated fabric further comprises a fiber different from cellulose diacetate and cellulose triacetate.
