Title:
MODIFIED ACETATE FIBER FABRIC AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JP3204915
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a fabric composed of a modified acetate fiber having ultra fine crimps, capable of preventing the weakening of the fiber to improve the tensile strength thereof, excellent in touch feeling with a smooth gross and a silky hand touch due to the fine crimps thereof, and having a sufficient strength for a use as a clothing, and to provide a method for producing the same fabric.
SOLUTION: This modified acetate fiber fabric is obtained by performing an alkali-treatment of an acetate fiber fabric in a spread state in an aqueous solution containing an alkali compound for converting the surface of the acetate fiber to a cellulose, then enzyme-treating the cloth with a cellulose decomposing enzyme to decompose and remove the part made as the cellulose and then heating the cloth at ≥96°C under a wet heat for developing crimps in a fiber axis direction. The acetate fiber contained in the fabric has ≥5000 crimps/m random crimps and ≥0.5g/d tensile strength.
