Title:
CONJUGATED SPUN FIBER OF CELLULOSE ACETATE, METHOD FOR PRODUCING THE SAME AND WOVEN OR KNITTED FABRIC THEREOF
Document Type and Number:
Japanese Patent JP2003055840
Kind Code:
A
Abstract:

To provide a conjugated spun fiber of cellulose acetate developing fine crimp by bending different from spiral state by hot water treatment and to provide a method for producing the conjugated spun fiber and to provide a woven or knitted fabric of the conjugated spun fiber.

This conjugated spun fiber of cellulose acetate is obtained by joining (A) a cellulose acetate in which 74-90% of hydroxy group of cellulose is acetized to (B) a cellulose acetate in which acetized hydroxy group is larger by ≥10% than that of the cellulose acetate (A) in a side-by-side type, and has an irregular cross section in fiber-axis direction and develops fine crimp different from spiral state by hot water treatment.
