A polymer blend fiber, which is a polymer blend fiber containing polypropylene (A), polyester (B), and styrene-ethylene-butylene-styrene copolymer (C), and is characterized by: It has at least one component selected from aromatic dicarboxylic acids, aromatic diols, and aromatic hydroxycarboxylic acids as the constituent component of polyester (B), the fiber diameter CV% is 0.1 to 2.5%, and the cross section of the fiber is an island The dispersion diameter of the components is 1 to 1000 nm.nn n n The present invention provides a polymer blend fiber, which has the characteristics of polypropylene and polyester, suppresses uneven fiber diameter between monofilaments, has excellent mechanical properties and abrasion resistance, and also suppresses uneven dyeing. It can be ideally adopted as a fiber structure. |
