NON-WOVEN FABRIC AND PROCESS FOR PRODUCING SAME

WIPO Patent Application WO/2010/074207

A1

Disclosed is a non-woven fabric (10) which comprises: core-sheath-type composite fibers each composed of a sheath part comprising a polyethylene resin and a core part comprising a resin component having a higher melting point than that of the polyethylene resin; and a hydrophilizing agent adhered on the surfaces of the core-sheath-type composite fibers.  The non-woven fabric has thermally fused parts which are formed by thermally fusing the intersection points of the constituent fibers.  The core-sheath-type composite fibers contain thermally extendable fibers which can extend in the length direction upon heating.  In each of the thermally extendable fibers, a hydrophilicity gradient is formed in the thickness direction and/or the planar direction of the non-woven fabric (10).  The non-woven fabric (10) can be used suitably as a surface sheet for an absorbent article and the like.
