<P>PROBLEM TO BE SOLVED: To provide a nonwoven fabric having low rough surface touch, suppressed fluffing and high recovery of bulkiness by hot air blasting. <P>SOLUTION: The nonwoven fabric 10 contains a thermally extensible fiber extending its length by heating and a thermally non-extensible hot-melt conjugate fiber containing two components having different melting points and subjected to drawing treatment. The blending ratio of the thermally extensible fiber to the hot-melt conjugate fiber (former/latter) is 20/80 to 80/20 by weight. The fiber diameter of the thermally extensible fiber is larger than that of the hot-melt conjugate fiber. The cross-points between the thermally extensible fibers, the cross-points between the hot-melt conjugate fibers and the cross-points between the thermally extensible fiber and the hot-melt conjugate fiber are thermally welded each in an air-through style. <P>COPYRIGHT: (C)2011,JPO&INPIT |
