发明名称 分割性凹凸複合繊維及びそれを用いてなる不織布
摘要 PROBLEM TO BE SOLVED: To provide a splittable concavo-convex composite fiber capable of producing a nonwoven fabric having high performance (effect) of absorbing water (retaining water), a method for effectively producing the splittable concavo-convex composite fiber, and a nonwoven fabric using the fiber.SOLUTION: The splittable concavo-convex composite fiber comprises a high-melting point component (A) containing a crystalline thermoplastic resin and a low-melting point component (B) comprising a resin composition containing a polyolefin-based resin (a) and an amorphous resin (b), has a cross-sectional shape in which the high-melting point component (A) and the low-melting point component (B) are mutually jointed to each other, and has a concavo-convex shape in a fiber surface part which is formed of the low-melting point component (B).
