Mold-in fastener products are made by forming a longitudinally continuous hook tape having a flexible base and an array of discrete male touch fastener elements extending from an upper surface of the base, forming a layer of flexible barrier material on the upper surface of the base, such that the male touch fastener elements are embedded in the layer of flexible barrier material, severing the flexible barrier material to form a pattern of patches of flexible barrier material spaced apart and surrounded by a continuous lattice of barrier material, stripping the lattice from the upper surface of the base to expose regions of the base between patches, and severing the hook tape along the exposed regions of the base to form individual mold-in fastener products, each having a patch of flexible barrier material surrounded by an exposed base edge region carrying male touch fastener elements.

Also provided is a hook-and-loop fastener including the layered article of the present invention. Also provided is a sanitary article including the layered article of the present invention. The layered article of the present invention includes at least one layer including a non-woven fabric of fiber, in which: the layered article has a fused portion; and the layered article has an index A, which is represented by the equation (1), of 0.9010.sup.6 m.sup.3/g or less: A=T/G (1) where T represents a thickness (unit: m) of the fused portion and G represents a basis weight (unit: g/m.sup.2).

[Object] [Solving Means] An attachable and detachable structure includes a superficial part and a base. The superficial part has an attachment part and a non-attachment part. The base supports the superficial part and moves one of the attachment part and the non-attachment part forward or backward to the other.

Described is a fastening tape that includes a plurality of attachment portions extending upwardly from a bottom portion of the fastening tape. The fastening tape also includes at least one inner wall disposed adjacent to at least some of the plurality of attachment portions and at least one outer wall offset from the at least one inner wall such that a cavity is disposed between the at least one inner wall and the at least one outer wall. Finally, the fastening tape includes an injected foam member disposed in the cavity.

An improved hook structure, of a soft hook strap of a hook-and-loop fastener, has a width W and includes: a hook body integrally protruding upright from a substrate of the hook strap; and a curved head portion curvedly bent downwardly from a top end of the hook body, the head portion including a hook end and a neck portion extending between the hook body and the hook end, wherein a lower side of the neck portion has a curvature defined by an imaginary circle located in a space between the hook body and the hook end and the head portion has a height H defined by points A and B on head portion which are intersection points of a imaginary vertical line passing through the center of the circle intersecting with an upper side and the lower side of the head portion respectively. The width W of the hook structure and the height H of the head portion satisfies a relationship defined below:

[00001]$0.1<.Math.1-\frac{H}{W}.Math.<0.3.$

An energy dissipating link for a tether includes: an elongated base having opposite, first and second end portions; a first touch fastener permanently coupled to the base proximate the first base end portion; and a second touch fastener permanently coupled to the base proximate the second base end portion. The second touch fastener is engageable with the first touch fastener to form a releasable closure defining a shear plane. With the first and second touch fasteners engaged to transmit a tensile load between the first and second end portions, and with the engaged touch fasteners loaded in shear in the shear plane, the base includes a longitudinally slack idler section between the first and second end portions. The idler section of the base is configured to transmit tensile load upon an energy-dissipating shear disengagement of the first and second touch fasteners by a tensile overload.

An energy dissipating link includes: an elongated base having opposite, first and second end portions; and a plurality of touch fasteners permanently coupled to the base, each of the plurality of touch fasteners releasably engageable with at least one other of the touch fasteners. The plurality of touch fasteners is arranged on the base to form first and second closures, each including engagements between respective fastening elements of two or more of the plurality of touch fasteners. The plurality of touch fasteners is configured such that: in response to a tensile load applied to the end portions of the base, the engaged touch fasteners of the first closure are loaded in shear along a shear plane; and in response to a tensile overload condition causing shear displacement of the touch fasteners of the first closure, the engaged touch fasteners of the second closure are subjected to a peel load.

A touch fastener having long and thin headed stems welded to and extending from, for example, a thin film, is made by orienting thin, hollow, drawn staple fibers between bristles of a brush, with no more than fiber ends sticking out of the brush, and then fusing a film to the fiber ends by direct welding. The fibers are then withdrawn from the brush as stems that are headed by heating their ends and allowing the resin to reform into an engageable head.

A vehicle cover assembly comprising; a flexible cover; one or more side rails; and a fastener assembly that is secured to a vehicle bed comprising; a cover fastener that is on one or more edge regions of the flexible cover; and a side rail fastener with one or more rows of fasteners comprising; a plurality of dual hooks on the base that releasably connect with the cover fastener of the flexible cover; and a plurality of spacers between the plurality of dual hooks.
