Abstract: A mechanical fastener is disclosed that includes a thermoplastic backing and multiple, upstanding fastening elements that have a post with a proximal end attached to the thermoplastic backing and a distal end comprising a cap larger in area than a cross-sectional area of the post. The basis weight of the mechanical fastener is in a range from 25 grams per square meter to 75 grams per square meter, and the height of the multiple, upstanding fastening elements is up to 300 micrometers. Fastening systems and disposable absorbent articles including the mechanical fastener are also disclosed.

Abstract: Provided are a fastening member and a fastening piece for which an unpleasant texture and an incongruous appearance are significantly reduced, and that bring about an integrated feeling with the main body of a disposable article for wearing. A fastening segment includes a hook fastener and a base sheet. A hook height H1 of a hook is set to 45 ?m to 150 ?m, and a hook sheet thickness T2 is set to 45 ?m to 75 ?m. When in an L*a*b* color coordinate system, a color difference of L* is ?L*, a color difference of a* is ?a*, and a color difference of b* is ?b*, a color difference ?E between the hook fastener and the base sheet calculated using the ?L*, the ?a* and the ?b*, is less than 5.5.
