PROBLEM TO BE SOLVED: To provide dyeable polypropylene fiber dyeable enough with a disperse dye, high in color fastness and producible in high operability. SOLUTION: The dyeable polypropylene fiber is such that 1-50 mass% of a copolyester is contained in polypropylene; wherein the copolyester is composed of terephthalic acid and two or more glycol components, the glycol component(s) being ethylene glycol, 1,4-butanediol and/or 1,6-hexanediol. The polypropylene fiber has a crystal melting point of 110-190°C. COPYRIGHT: (C)2008,JPO&INPIT
