Claim:
A heat-embossed, fastening non-woven fabric comprising, as at least one component, core-sheath or side-by-side heat-fusing composite staple fibers of 30 to 300 mm in length having a low-melting polymer component on a fiber surface, a number of crimp of 10 to 20 crimps/inch and a percentage crimp of 5 to 20%, wherein a front surface of the non-woven fabric comprises a non-embossed portion and an embossed portion, the non-embossed portion being a large number of regularly or irregularly dispersed convex island regions upwardly projecting from the front surface of the non-woven fabric, a base portion of each convex island region having an area corresponding to an area-based equivalent circle having a mean diameter of 2 to 8 mm, the embossed portion being a sea region surrounding each island region, and at least one end of the composite staple fibers in the non-embossed portion that constitute the convex island regions being press- and heat-anchored at the embossed portion that constitute the sea region.
