  • Patent number: 8079995
    Abstract: A method of manufacturing a composite fastener material, the composite fastener material, and products derived from the composite fastener material. The method includes providing two longitudinally continuous sheets of material, positioning the two sheets to form a longitudinal, continuous interface between the two sheets, joining the two sheets by introducing one or more molten plastic resins in at least one lane, one lane of the resin extending across the interface under conditions that cause the resin to bond to the two sheets, molding an array of stems from at least one lane of the resin, the stems extending from an exposed surface of the composite material, and forming engageable heads on the stems to form fastener elements, wherein the two sheets differ from one another by one of material composition, thickness, texture, stretchability, breathability, and compressability.

  • Patent number: 7608070
    Abstract: In one embodiment of the present invention, an article has a mechanical fastener and configured is to be worn by a user. The article comprises a body portion configured to be worn by a user. The body portion may include a fibrous landing layer wherein the fibrous landing layer comprises a plurality of fibers. The body portion may also include a foam layer, such that the foam layer has a first surface comprising a plurality of free-stranding struts adapted for engaging at least a portion of the plurality of fibers of the landing layer. The foam layer and fibrous landing layer are capable of being engaged with a Shear Resistance of about 100 grams of force or greater per square centimeter and a Peel Resistance of about 50 grams or less of force per square centimeter.

  • Patent number: 7444722
    Abstract: A male component of a mechanical fastening system, such as a hook and loop fastener, that can remain fastened to a female component under high levels of shear force. The male component has a backing material with protrusions extending from the backing material at an angle toward the direction of fastener force. The combination of the male component with a female loop component results in a secure fastening system.

  • Publication number: 20070119032
    Abstract: 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.

  • Publication number: 20070099530
    Abstract: In some embodiments, a nonwoven fabric includes a first web that is at least partially formed of extruded strands which include an auto-adhesive material. The nonwoven fabric is adapted to be bonded to another item that includes a similar auto-adhesive material. In other embodiments, a method of forming a nonwoven fabric includes extruding a plurality of strands that are formed of an auto-adhesive material. The method further includes routing the plurality of strands toward a moving support, depositing the plurality of strands onto the moving support, and then stabilizing the plurality of strands to form a web. In other embodiments, a fastening system includes a nonwoven fabric that has a web which is formed of a plurality of extruded strands that include an auto-adhesive material. The fastening system further includes a foam layer that has a surface with a plurality of free-standing struts that include a similar auto-adhesive material.
