Abstract
A fastening tape has a sheet-form base carrying an array of hooking members (10,22,24,34) each having a height (h) of about 0.008 inch (0.2 millimeter) or less, as measured from the base, and fiber-engaging features, such as re-entrant tips (18,32), disposed less than about 0.003 inch (0.08 millimeter) from their upper surfaces, as measured normal to the base. Such hooking members are employed to releasably engage directly into foams and fine denier non-woven materials, such as those of insulation, filters, construction moisture barriers, disposable gowns and diapers.

A fastening tape comprising
- a sheet-form base carrying an array of hooking members (10,22,24), each hooking member having a stem (14,14′,28) integrally molded with and extending from a side of the base, and a head (16,16′,26) overhanging the base in a common direction, along the tape, the head extending from the stem to a distal, re-entrant tip (18,18′,32) to define an engageable crook (20,30);
- wherein
- the hooking members each have a height (h) of about 0.008 inch (0.2 millimeter) or less, as measured from the base;
- and
- the re-entrant tips (18,18′,32) are each disposed less than about 0.003 inch (d, 0.08 millimeter) from an upper surface of their respective hooking members, as measured normal to the base.
