  • Patent number: 6403159
    Abstract: A laminate film has a composite structure and a bonding surface that eliminates the formation of air bubbles during the lamination process. A process for forming the laminate film includes spreading a PET film with an adhesive, drying the adhesive, and spreading a PE film, which is in a melted phase, on the dried adhesive, to form a composite film. An EVA fluid is spread on the PE film of the composite film, and the composite film with the EVA fluid is passed between first and second rollers. The first roller has a pockmarked surface and contacts the EVA fluid, thereby forming a pockmarked surface on the EVA fluid.

    Abstract: An ink transfer sheet and method for using the same. The transfer sheet includes a backing layer, a release layer on the backing layer, and an ink receiving layer on the release layer. The ink receiving layer contains a quaternary ammonium salt thereon or impregnated therein. To use the transfer sheet, an ink containing an anionic coloring agent is applied to the ink receiving layer, preferably using thermal inkjet methods. Thereafter, the transfer sheet is positioned on a fabric substrate. Heat is applied to the sheet which causes the release layer and ink receiving layer to adhere to the substrate. The backing layer is then detached from the release layer leaving the release and ink receiving layers (with the printed image thereon) on the substrate. This process transfers the image to the fabric substrate, with the image being stabilized by interactions between the quaternary ammonium salt and anionic coloring agent.

    Abstract: A printable heat transfer material having cold release properties, which material includes a flexible first layer having first and second surfaces. The first layer typically will be a film or a cellulosic nonwoven web. A second layer overlays the first surface of the first layer and includes a thermoplastic polymer, such as a hard acrylic polymer or a poly(vinyl acetate). A third layer overlays the second layer and includes a thermoplastic polymer which melts in a range of from about 65° C. to about 180° C. The first layer may be a cellulosic nonwoven web, such as a latex-impregnated paper. The thermoplastic polymer of which the second layer is composed may have a glass transition temperature of at least about 25° C. The second layer also may include an effective amount of a release-enhancing additive, such as a divalent metal ion salt of a fatty acid, a polyethylene glycol, or a mixture thereof.

  • Patent number: 6194044
    Abstract: An emblem for embroidery stitching directly to a substrate is disclosed which provides an emblem which can be readily embroidered. The emblem includes a fabric layer with a thermoplastic adhesive coating one side of the fabric layer and a pressure sensitive adhesive coating the thermoplastic adhesive to provide an emblem which can temporarily adhere to a substrate. The emblem can thus be temporarily secured during embroidery and prevent distortion of the emblem. Following embroidery, the emblem is heat-sealed to a substrate and the thermoplastic adhesive coating penetrates through the pressure sensitive adhesive for attachment of the emblem to the substrate.

  • Patent number: 6168851
    Abstract: A hot-melt web has a buffer adhesive layer of a thermosetting resin on a light transmissive, heat resistant resin support. The hot-melt web has the advantages of light transparency, heat resistance, weather resistance, controlled entrainment of bubbles and easy removal of bubbles during thermocompression bonding, provides a sufficient bonding force, and effectively corrects random deformations of a module sheet. The hot-melt web is suitable for use in the bonding, joining and laminating steps in the manufacture of optical discs such as DVD and flat panel displays, is easy to eliminate bubbles, and is effective for improving the quality of an associated product. A laminate using the hot-melt web and a method for preparing the laminate are also provided.

  • Patent number: 6117528
    Abstract: The present invention is an improved device for delivering a release agent to fuser rollers employed in various printer devices, such as laser printers, fax machines, copier machines, etc. The release agent delivery device of the present invention comprises an elongated web of microporous membrane (e.g., expanded polytetrafluoroethylene) bonded to a substrate, filled with release agent, and mounted between two shafts. The web spans across the fuser roller so that the roller is simultaneously cleaned and oiled during normal operation. When the portion of the web in contact with the fuser roller becomes contaminated or expends its release agent supply, the web can be advanced to place a fresh surface in contact with the fuser roller.

  • Patent number: 6110565
    Abstract: A heat bond seaming tape has a base formed of a sheet of paper or a paper-like material and an overlying strip of an open mesh material. A plurality of transversely spaced, longitudinally extending beads of a hot melt thermoplastic adhesive material is placed on a top surface of the mesh for adhering the tape to the backs of adjacent carpet edges. A strip of a polyolefin such as a semi-rigid high density polyethylene material is sandwiched between the base sheet and the strip of open mesh material and extends longitudinally along the center of the strip and extends transversely across the carpet seam to prevent seam buckling. The base sheet and reinforcing strip can be extruded as an integral one piece member of the high density polyethylene prior to being joined with the mesh and hot melt adhesive.
