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.
Claims65
A wearable garment with a non-woven material broadly covering an outer surface thereof, and a piece of fastening tape permanently attached to one region of the non-woven material and releasably engaging another portion of the non-woven material,
- the fastening tape comprising a sheet-form base carrying an array of hooking members, each hooking member having a stem integrally molded with and extending from a side of the base, and a head overhanging the base in a common direction along the tape, the head extending from the stem to a distal, re-entrant tip to define an engageable crook;
- wherein the hooking members each have a height of about 0.008 inch or less, as measured from the base, and the re-entrant tips are each disposed less than about 0.003 inch from an upper surface of their respective hooking members, as measured normal to the base;
- with the hooking members of the fastening tape each directly engaging the non-woven material.
A roll of moisture barrier construction wrap material having a length of fastener tape permanently secured thereto, the fastener tape comprising
- a sheet-form base carrying an array of hooking members, each hooking member having a stem integrally molded with and extending from a side of the base, and a head overhanging the base in a common direction along the tape, the head extending from the stem to a distal, re-entrant tip to define an engageable crook;
- wherein
- the hooking members each have a height of about 0.008 inch or less, as measured from the base;
- and
- the re-entrant tips are each disposed less than about 0.003 inch from an upper surface of their respective hooking members, as measured normal to the base.
A releasable fastening comprising
- a length of fastener tape as a first half of the fastening, the fastener tape comprising a sheet-form base carrying an array of hooking members, each hooking member having a stem integrally molded with and extending from a side of the base, and a head overhanging the base in a common direction along the tape, the head extending from the stem to a distal, re-entrant tip to define an engageable crook;
- wherein the hooking members each have a height of about 0.008 inch or less, as measured from the base, and the re-entrant tips are each disposed less than about 0.003 inch from an upper surface of their respective hooking members, as measured normal to the base;
- and
- an open cell foam as a second half of the fastening;
- wherein the hooking members of the fastener tape are disposed within apertures of an open cell structure of the foam to engage reticulated portions of the foam in their crooks.
A method of covering a structure, the method comprising providing a covering consisting essentially of
- a sheet of non-woven material;
- and
- a length of fastener tape permanently secured to the non-woven material in a first region thereof, the fastener tape comprising a sheet-form base carrying an array of hooking members, each hooking member having a stem integrally molded with and extending from a side of the base, and a head overhanging the base in a common direction along the tape, the head extending from the stem to a distal, re-entrant tip to define an engageable crook, the hooking members each having a height of about 0.008 inch or less, as measured from the base, and the re-entrant tips each disposed less than about 0.003 inch from an upper surface of their respective hooking members, as measured normal to the base;
- wrapping the structure with the covering, such that a second region of the non-woven material overlaps the fastener tape in the first region;
- and
- engaging the hooking members of the fastener tape directly into the non-woven material to releasably secure the covering to itself.
A method of securing a garment, the method comprising
- providing a garment with a non-woven material broadly covering an outer surface thereof, and a piece of fastener tape permanently attached to one region of the non-woven material, the fastener tape comprising a sheet-form base carrying an array of hooking members, each hooking member having a stem integrally molded with and extending from a side of the base, and a head overhanging the base in a common direction along the tape, the head extending from the stem to a distal, re-entrant tip to define an engageable crook, the hooking members each having a height of about 0.008 inch or less, as measured from the base, and the re-entrant tips each disposed less than about 0.003 inch from an upper surface of their respective hooking members, as measured normal to the base;
- overlapping a second region of the non-woven material with the fastener tape in the first region;
- and
- engaging the hooking members of the fastener tape directly into the non-woven material to releasably secure the non-woven material of the garment to itself.
