ABSTRACT:
Provided is a composite fiber comprising an ethylenevinyl alcohol copolymer (component A) and a polyester (component B) heterogeneously blended with each other. In the cross section of the fiber, component A is distributed in islands form locally, and the region of component B where component A is not present containing a component B zone containing a circular area having a diameter at least 1/20 that of the fiber. By assuming the above structure, the fiber has good bulk, touch and silhouette, and a feeling similar to that of natural fibers, having solved the problems inherent to polyester fibers, such as oil soiling, soil redeposition by washing and soiling by sublimation and migration of disperse dye, while making use of superior features of polyester fiber, such as high strength, modulus, abrasion resistance, chemical resistance, weather resistance and dimensional stability.
