Methods to modify an engaging surface of a fibrous landing layer of a mechanical fastener are generally disclosed, along with products made from the same. For instance, the engaging surface of the landing layer can be mechanically modified to increase the fuzziness of the layer, which allows more fibers to engage the other surface of the mechanical fastener. For example, the improved engaging surface of the landing layer can increase the shear resistance of a mechanical fastener comprising a foam layer and a landing layer. |

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. |

Clothlike materials may become abraded upon disengagement of mechanical fasteners. This abrasion may cause a decrease in aesthetic appeal, as well as a decrease in functionality of attachment systems. As a result, there has remained a need for improved fastening systems. Moreover, there has remained a need for improved fastening systems for disposable absorbent articles. |

The hook portion generally includes a support and a plurality of closely spaced upstanding hook elements extending from one side thereof, wherein the plurality of hook elements comprises or incorporates a shape memory polymer. When the hook portion and loop portion are pressed together they interlock to form a releasable engagement.

Introducing a thermal activation signal to the plurality of hook elements causes a change in shape orientation and/or flexural modulus that 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. Also disclosed herein are processes for operating the releasable fastener system. |

An electrically releasable form of hook and loop fastener (10) allows one half of the fastener to release from the other half without applying direct physical force to either half. The hook elements (21) of the fastener are formed of a shape-memory alloy material (27) such as commercially available Ninitol. Release of the hook half (14) of the fastener from the loop half (12) is accomplished by passing an electrical current through the shape-memory alloy material to straighten the hooks (21) so that they release their engagement with the loops (18). The flow of electricity through the hook half energizes the Ninitol material (27) to change its shape, either expanding or contracting in length; the change in shape is made to act against another length of material (28) 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 (21) to their hook shape, ready for re-engagement with the loops (18) upon conventional mating of the two halves of the fastener. Release and re-engagement can be repeated, substantially indefinitely. |

A running length of fastener product is formed of longitudinally pre-oriented synthetic resin. The product is characterized by a base web and an array of discrete fastener elements protruding from at least one side of the web, the web being in a laterally stretched molecular oriented condition. After forming a preform having discrete fastener elements integral with a base web in a stretchable state, the preform is stretched in a manner that substantially increases the fastener element spacing and reduces the thickness of the base web. A machine is shown that is capable of lengthwise orienting before forming and widthwise stretching after forming, which employs controlled heating to render the product widthwise stretchable while preserving or achieving a desired shape of the fastener elements. There are shown fastener products that include products that are laterally stretched to between two and ten times the width of the original preform fastener products, having lateral rip resistance due to molecular orientation of film form webs produced by stretching, applied to complex or extensive surfaces. Also shown are laminated products formed by joining an added material to the stretched web, and methods for laminating. |
