  • Patent number: 5543004
    Abstract: Stitchbonded articles and methods of making same are presented. The articles may be either dual purpose wiping/scrubbing articles or only scrubbing articles. The articles may be constructed to have three dimensional scrubbing surfaces. Both the dual purpose articles and the scrubbing articles comprise thermoplastic nodules melt-bonded to the stitching yarn, and preferably to the fibers of an absorbent material, the nodules providing the primary scrubbing utility.

  • Patent number: 5540982
    Abstract: The present invention provides a unique knit construction having a nonfiberglass stiffness-controlling yarn in the fabric of the backing. Preferably, the nonfiberglass stiffness-controlling yarn is used in combination with a heat shrinkable yarn or a stretch yarn, and alternatively a nonfiberglass microdenier yarn. More preferably, the nonfiberglass stiffness-controlling yarn is in combination with a stretch yarn and a nonfiberglass microdenier yarn. Most preferably, the nonfiberglass stiffness-controlling yarn is in combination with a heat shrinkable, elastically extensible yarn, and a nonfiberglass microdenier yarn.

  • Patent number: 5368668
    Abstract: A stitchbonded absorbent article and method of making same are presented. The article exhibits good hand, repeated washing durability, and absorbency. The article includes first and second layers which are mechanically held together by stitches of yarn, at a stitch density ranging from about 15 to about 35 st/10 cm, and stitch gauge ranging from about 10 to about 40, using a stitching yarn comprising at least two compositionally different fibers having different heat stability being at least partially melt-bonded together at points of mutual contact, the yarn being melt-bonded at least partially to outer surfaces of the article.

  • Patent number: 5308667
    Abstract: A web of adhesive, especially a normally tacky and pressure-sensitive adhesive, is rendered electrically conductive by imparting a pattern of electrically conductive elements that extend from slightly beyond one face of the web to slightly beyond the other face of the web. In a preferred embodiment, the adhesive web is sandwiched between release liners formed of uniaxially oriented film and a conductive thread stitched through both the liners and the adhesive web. The liners can be removed, tearing along the stitch lines, to create an electrically conductive adhesive web.

  • Patent number: 4931343
    Abstract: A method for forming a sheet material adapted to be cut into smaller pieces to form portions of a fastener. The method comprises providing a self supporting polymeric film that provides the structural strength to retain the integrity of the sheet material, and stitching a plurality of yarns through the film to form loops projecting from one surface of the film and locking portions of the stitches adjacent the opposite surface of the film. The sheet material can also include a layer of heat softenable polymeric material adhered to the film over the locking portions.

  • Patent number: 4770917
    Abstract: A method for forming a sheet material adapted to be cut into smaller pieces to form portions of a fastener. The method comprises providing a backing laminate comprising a layer of base material and a sealing layer of heat softenable polymeric material along a back surface of the base material; stitching a plurality of yarns through the base material to form loops projecting from a face surface of the base material and locking portions of the stitch adjacent the back face of the base material; and heating the polymeric material to adhere it to the locking portions of the stitches. The sheet material can then be used if loops are desired, or the loops can be cut to form hooks or heated to form headed projections on the sheet material.

  • Patent number: 4750324
    Abstract: The present invention makes possible fabrics stitchbonded with or knitted from brittle yarns by providing a composite yarn which is able to be used in commercial stitchbonding and knitting machines, the new composite yarn comprising a load-bearing core yarn, a brittle yarn and a wrap yarn which secures the core yarn and the brittle yarn together. The wrap yarn may be helically wrapped around the load-bearing core yarn and the brittle yarn, or the wrap yarn may secure the load-bearing core yarn and the brittle yarn together with a series of connected loops forming a knitted pillar of chain stitches.
