Abstract
A mechanical fastener including a loop member includes a base sheet and a plurality of continuous filaments extending substantially parallel one to another on one surface of the base sheet substantially parallel one direction and the filaments are bonded to the base sheet along at least a pair of bonding zones extending transversely of the filaments to form a plurality of loop elements extending between the pair of bonding zones.
Claims6
A mechanical fastener comprising:
- a loop member releasably engaged by a hook member, said loop member comprising:
- a heat-sealable base sheet;
- and
- a plurality of continuous heat-sealable filaments formed from a deregistered continuous tow filament,
- said plurality of continuous filaments extending on one surface of said base sheet substantially parallel to one another in one direction and being bonded to said base sheet by a plurality of first and second bonding zones, said first bonding zones being arranged at substantially regular intervals between transversely opposite side edges of said loop member substantially parallel to said continuous filaments and said second bonding zones are arranged at substantially regular intervals between longitudinally opposite side edges of said loop member orthogonally to said first bonding zones to define a plurality of loop-crowded regions.
