BULKY NONWOVEN FABRIC AND BODY FLUID-ABSORBING ARTICLE HAVING THE SAME ON SURFACE LAYER

摘要

PURPOSE:To obtain the title nonwoven fabric having excellent recovery after compression for many hours by arranging a component comprising polybutylene terephthalate and polyethylene terephthalate and a component such as polyethylene in side by side type or sheath-core type and thermally fusing both the components by the latter. CONSTITUTION:(A) A first component comprising 100-70wt.% polybutylene terephthalate-based polymer and 0-30wt.% polyethylene terephthalate-based polymer and (B) a second component comprising a polyethylene-based polymer are subjected to conjugate spinning in such a way that both the components are arranged in a fiber section in side by side type or in sheath-core type of the first component as core and the second component as sheath wherein the centers of the gravity of both the components are not superimposed and the conjugation ratio of the first component and the second component is (70:30)-(40:60), the conjugate yarn is made into web containing >=30wt.% of the conjugate yarn, which is heat-treated and thermally fused by the second component of the conjugate yarn to give the aimed bulky nonwoven fabric.
