  • Patent number: 9826801
    Abstract: A male touch fastener strip includes an elongated base and a field of male fastener elements each having a stem extending from a broad face of the base and a head for engaging fibers. The fastener element stems and broad face of the base together form a unitary mass of resin, such as a resin containing a magnetically attractable substance. Wings extend from respective longitudinal edges of the base and define discrete corrugations extending in a series along the fastener strip and forming corresponding undulations in the rear face of the strip along its longitudinal edges. The corrugated wings can also support a foam gasket.

    Abstract: A touch fastener product has a base strip of resin carrying both mechanical fastener projections and adhesive, in some cases disposed on raised portions of the base strip. The fastener projections are arranged in discrete fields with lanes between the fields, and the adhesive is disposed within the lanes. The adhesive in each lane is shorter, as measured perpendicularly from the base strip, than the projections nearest the lane, by a distance that is less than ten percent of the width of the lane. In some cases molded stems extend through the adhesive in the lanes. The fastening face of the molded base strip is treated to give the fastening face a higher surface energy than the back face, to resist adhesive delamination during unspooling.

    Abstract: A hook surface fastener excellent in the heat resistance, flame resistance, retention of hook shape, and pull-out resistance of hook engaging elements (fibers). The hook surface fastener is composed of a base fabric and the hook engaging elements formed on the base fabric. The base fabric is a woven fabric composed of warp yarns, weft yarns and fibers constituting the hook engaging elements. The warp yarns and the fibers constituting the hook engaging elements are polyphenylene sulfide fibers. The weft yarns are substantially non-twisted, paralleled yarns of polyphenylene sulfide fibers and heat-fusible fibers having a melting point or softening point each being 230° C. or lower. The polyphenylene sulfide fibers constituting the hook engaging elements have a crystal orientation of 85.0 to 90.0% and a crystallinity of 32.0 to 42.0% so that the retention of hook shape is good. The fibers constituting the hook engaging elements are anchored to the base fabric by fusion of the heat-fusible fibers.

For this, the dry adhesive fastening system includes a first adhesion member having a first microvillus disposed on a first board and a second adhesion member having a second microvillus disposed on a second board to contact the first adhesion, thereby providing adhesion. Also, unlike the existing velcro fastening system, the hook and loop may not be classified to improve production yield and effectiveness. Also, during the attachment/detachment, the noises may do not occur. In addition, since the microvillus having the micro or nano size is used, the adhesion may be realized even though a very small area is provided.

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.

  • Patent number: 6733860
    Abstract: The invention relates to an adhesive closing part, especially for foaming upholstery parts of car seats during production of the latter, comprising adhesive elements (10) arranged on one side for connection to corresponding adhesive elements of another adhesive closing part by forming an adhesive closure and connecting elements on the other side of the adhesive closing part for producing a connection to the corresponding foam material. A reliable and high-strength connection to the foam material is achieved due to the fact that the connecting elements consist of an adhesive medium, especially a fluorine gas, applied at least on the other side of the adhesive closing part.

  • Patent number: 6728998
    Abstract: A woven fastener product includes an array of hook elements and an array of loop elements that extend from the surface of different respective regions of a common fabric base. The arrays are formed by warp yarns, the arrays being separated in the warp direction of the fabric base. To form a self-engaged fastening, the fastener product is conformed so that the hook elements overlie the loop elements. Monofilament loops are shown sized and located to provide pin-receiving mounting sleeves as part of the woven structure.

  • Patent number: 6692674
    Abstract: A fastener product includes a planar base, multiple discrete plateaus molded integrally with and extending from an upper surface of the base each plateau having an upper surface that is smaller in area than an overall area of the base covered by the plateau, and an array of discrete fastener elements integrally molded with and extending from the upper surface of the plateau. The product is molded on a mold roll covered by a sleeve either made of a resilient material or having apertures intersecting an inner surface of the sleeve at an inner opening that is smaller than an outer opening of the aperture at an outer sleeve surface to form an edge of the fastener product of decreased sharpness.

  • Patent number: 6681457
    Abstract: 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.

  • Patent number: 6645600
    Abstract: A hook and loop fastener having an increased coefficient of friction compared to conventional nonwoven hook and loop systems. The increased coefficient of friction strengthens engagement between a hook component and a loop component, both when the hooks and loops are engaged, and even when the hooks and loops are not engaged but merely in contact with one another. The coefficient of friction can be increased by adding tackifiers in the hook forming process and/or in the loop forming process, or by extruding multi-component fibers using a fiber type that enhances strength and a fiber that has less strength but has a higher coefficient of friction, or by using fibers of various cross-sectional shapes, or by processing surface bloom additives into the hook and/or loop structures.

  • Patent number: 6623469
    Abstract: The invention is a refastenable mechanical fastening system, made of free formed prongs joined to a substrate. The prongs taper and are nonperpendicularly oriented relative to the plane of the substrate. Each prong has an engaging means projecting laterally from the periphery of the prong. The free formed prongs are manufactured by the process of depositing liquid material onto a moving substrate, stretching the liquid material in a direction parallel to the plane of the substrate and severing the stretched material to form the distal end and engaging means of the prong. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbent garment, specifically a diaper, is also disclosed.

  • Patent number: 6598274
    Abstract: 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.
