PROBLEM TO BE SOLVED: To provide a method for producing a conjugate fiber excellent in flexibility and improved in chlorine resistance. SOLUTION: By adjusting the molecular weight, molecular weight distribution and fine structure of the conjugate fiber, it is possible to exhibit a high flexibility such as≥30% natural crimp stretch and≥70% natural elastic recovery rate without separately performing a dyeing or post processing such as with boiling water or dry heating at or higher than a prescribed temperature, and also to produce the conjugate fiber having≥85% strength-maintaining rate and≥80% flexibility-maintaining rate after a chlorine treatment, and also extremely excellent in elasticity, chlorine resistance and stability by applying a post processing or washing utilizing industrial water, tap water, underground water, etc. COPYRIGHT: (C)2006,JPO&NCIPI
