(57) [Summary] [Purpose] To provide a method which has a good process passability before the splitting treatment and can be easily split into fine fibers during the splitting treatment. [Structure] Each component of the splittable conjugate fiber is made of ethylene terephthalate-based polyester, while the component is a splittable conjugate fiber containing 3 to 50% by weight of polyalkylene glycol, which is subjected to mechanical stress in the presence of water. Divide into each component. [Effect] Since polyalkylene glycols are blended in one component, coexistence of water causes water swelling to generate strain in the joint surface with the other component, and mechanical stress allows easy division. |
