Heat-fusible composite fiber, and non-woven fabrics and absorbent products produced from the same

摘要

There are disclosed a heat-fusible composite fiber comprising a component A consisting of a high-melting-point, crystalline polypropylene resin, and a component B consisting of at least one low-melting-point resin selected from propylene-based copolymers having a melting point lower than that of the component A, characterized in that the cross-section of said composite fiber has a profiled structure wherein the component A consisting of the high-melting-point resin forms branch portions of strands radially extending from the center portion outward, and the component B consisting of the low-melting-point resin forms projecting portions connected to the branch portions, and a non-woven fabric and absorbent products produced from such a fiber.
