A creped nonwoven web having permanent crepe includes regions of interfilame nt bonding which are permanently bent out-of-plane, alternating with regions of no interfilament bonding. The non-bonded regions include a multiplicity of filament loops which terminate at both ends in the creped interfilament-bonded regions. The creped nonwoven we b is useful as the female component of a hook-and-loop fastener, and can also be used in diaper outercovers, liners, transfer and surge layers, wipers, and other fluid handling products. The web may also be creped using a hydrophilic adhesive, and used as a fluid transfe r liner in absorbent structures such as diapers, with a hydrophilic surface facing the absorbent core.
