A method of nondestructive, reversible fixing of a coherent layer to a substrate, comprising the steps of anchoring a nonfibrous coherent layer to a film having either or both of projecting or embedded anchoring elements, wherein the anchoring elements provide mechanical anchorage of the coherent layer to the film, and fixing the coherent layer and film to the substrate. The coherent layer is anchored by applying a liquid or paste form material to the substrate that sets on the substrate to form the coherent layer, which is nonadhesive or only slightly adhesive to the film. |

A releasable fastener system comprises a loop portion and a hook portion. The loop portion includes a support and a loop material disposed on one side thereof whereas the hook portion includes a support and a plurality of closely spaced upstanding hook elements extending from one side thereof. When the hook portion and loop portion are pressed together they interlock to form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. The hook elements are formed of a magnetorheological elastomer that provides a change in shape orientation and/or flexural modulus of the hook elements. In this manner, the shape orientation and/or flexural modulus of the hook elements can be remotely changed to provide a reduction or magnification in the shear and/or pull-off forces in addition to providing variable damping capabilities to the fastener system. |

A releasable fastener system comprises a loop portion and a hook portion. The loop portion includes a support and a loop material disposed on one side thereof. The hook portion includes a support and a plurality of closely spaced upstanding hook elements extending from one side thereof, wherein the plurality of hook elements comprises a fiber and a shape memory alloy coating deposited onto the fiber, and wherein the fiber and the shape memory alloy coating comprises a non-axisymmetric coating or deposition of the shape memory alloy about a portion of the fiber. When the hook portion and loop portion are pressed together they interlock to form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. Introducing a thermal activation signal to the plurality of hook elements causes a change in shape orientation, flexural modulus property, or a combination thereof that is effectively reduces the shear and/or pull off forces in the releasable engagement. In this manner, disengagement of the releasable fastener system provides separation of the hook portion from the loop portion under controlled conditions. |

A releasable fastener system comprises two hook portions. The hook portions each include a support and a plurality of closely spaced upstanding hook elements extending from one side thereof. When the two hook portions are pressed together they interlock to form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. The head elements of the hook elements are formed of a material that provides a change in directional orientation of the head elements. In this manner, the directional orientation of the head elements of the hook elements can be remotely changed to provide a reduction or magnification in the shear and/or pull-off forces. |

A fastening device comprising a pair of attachment pads, one pad having a surface from which stems project, a second pad formed with openings and receptacles, each opening and receptacle adapted to receive a stem, the pads becoming interlocked by the fit of the stems in the receptacles. A woven, knit or knotted material of open texture having holes, preferable evenly spaced holes such as those of a screen or net, is secured between the pads by passing the stems through the mesh and into the receptacles. The pads and mesh material, so arranged, are secured to a structure by a bracket or clamp that is fixed to the attachment pads and mesh material. |

A finishing method for obtaining a fiber surface fastener, said method being capable of, with simple processes, firmly fixing entangling portions between a foundation cloth composed of knitted/woven structure or nonwoven fabric and base portions of engaging elements, further, the finishing method being capable of preventing coating agent from adhering to or solidifying on the protruding surfaces of the engaging elements, said surface fastener having excellent softness. While a fiber surface fastener in which a plurality of engaging elements are formed on a foundation cloth thereof is conveyed continuously, powdery hot-melt adhesive is applied to its engaging element formation face from a separate position, the surface fastener is heated at a temperature higher than a melting point of said adhesive for a required time so that the adhesive applied is melted between the base portions of the engaging elements and the foundation cloth, and then said surface fastener is cooled. |

An electrically releasable form of hook and loop fastener allows one half of the fastener to release from the other half without applying direct physical force to either half. The hook elements of the fastener are formed of a shape-memory alloy material such as commercially available Ninitol. Release of the hook half of the fastener from the loop half is accomplished by passing an electrical current through the shape-memory alloy material to straighten the hooks so that they release their engagement with the loops. The flow of electricity through the hook half energizes the Ninitol material to change its shape, either expanding or contracting in length; the change in shape is made to act against another length of material that remains fixed in length or changes shape in an opposite direction so as to cause the hook shape to straighten toward a rod shape. Upon termination of the flow of electrical energy, the hooks return to their hook shape, ready for re-engagement with the loops upon conventional mating of the two halves of the fastener. Release and re-engagement can be repeated, substantially indefinitely. |

A bi-stable hook component of a touch fastener can bend into, and remain in, a stable concave position. Another stable position enables initial engagement with a mating component (e.g., a loop component). The concave position applies engagement-enhancing tension to the engaged loops, and in some cases forces end portions of the hooks into close proximity with one another to secure the fastening and to produce a curved touch fastener that, as engaged, can better conform to an underlying curved surface, such as the contour of a wearer's body. Absorbent articles having such a bi-stable fastening system are also disclosed. |
