NON-WOVEN FABRIC

WIPO Patent Application WO/2010/074208

A1

Disclosed is a non-woven fabric (10, 110) which comprises composite fibers each comprising a first component and a second component having different melting points from each other, and which has, formed therein, many thermally fused points produced by thermally fusing the intersection points of the composite fibers.  When the state of the non-woven fabric (10, 110) is changed from dried state to wet state, the percentage of change in thickness of the non-woven fabric (10, 110) is 15% or more.  In a non-woven fabric (10) which is an embodiment of the non-woven fabric, the composite fibers is fibers each comprising a polypropylene resin or a polyethylene terephthalate resin as the first component and a resin having a lower melting point from that of the first component as the second component and has a Young’s modulus of 0.2 to 1.0 GPa.
