Publication number: 20030008142Abstract: Improved polypropylene fibers exhibiting greatly reduced heat- and moisture-shrink problems are provided. Such fibers require the presence of certain compounds that quickly and effectively provide rigidity to the target polypropylene fiber after heat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropyelene after exposure to sufficient heat to melt the initial pelletized polymer and upon allowing such a melt to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling. In such a manner, the “rigidifying” nucleator compounds provide nucleation sites for polypropylene crystal growth. After drawing the nucleated composition into fiber form, the fiber is then exposed to sufficient heat to grow the crystalline network, thus holding the fiber in a desired position.Type: ApplicationFiled: May 17, 2001Publication date: January 9, 2003Inventors: Brian G.

Patent number: 5941186Abstract: A high-security fabric for use in high-security applications comprising an inner layer of nylon having top and bottom surfaces, two inner layers of polyester, one of the inner layers of polyester extending on the top surface of the inner layer of nylon, the other inner layer of polyester extending on the bottom surface of the inner layer of nylon, and two outer layers of a fireproof synthetic fabric, each outer layer of fireproof synthetic fabric extending on one of the inner layers of polyester opposite to the inner layer of nylon. All of the layers form a 5-ply assembly having a top and a bottom and in which the inner layer of nylon is centrally positioned. The assembly is stitched together with a nylon thread in a pattern.Type: GrantFiled: January 29, 1998Date of Patent: August 24, 1999Inventor: Giovanni Argentino

Patent number: 5882770Abstract: A fibrous sheet is provided with an outer surface having fibrous elements which are embossed with a pattern of fine grooves that are substantially aligned from fibrous element to fibrous element. The pattern of fine grooves is embossed directly on the surface of the fibrous sheet and produces rainbow and/or hologram images on exposure to light. In contrast, prior fabrics for producing rainbow or hologram images were laminated to plastic or metal foils having pre-embossed patterns of grooves. Sheets and fabrics of the present invention are free from such impermeable foils and retain desirable attributes of breathability and other aesthetic qualities.Type: GrantFiled: December 31, 1996Date of Patent: March 16, 1999Inventor: Munzer Makansi

Method and apparatus for treating the surface of a web or film, and webs and films treated therewith
Patent number: 5766425Abstract: The surface of a web or film is modified to impart the material with improved properties including wettability, printability, adhesion and static reduction. Such surface modification is achieved with an electrode structure which causes a filamentary discharge to pass generally horizontally across a surface of the electrode structure. A substrate to be treated is then positioned adjacent to the surface of the electrode structure so that the filamentary discharge is caused to flow horizontally across the surface of the substrate, in turn modifying the surface of the substrate and achieving the desired improvement in properties.Type: GrantFiled: January 26, 1996Date of Patent: June 16, 1998Assignee: The University of Tennessee Research CorporationInventor: Igor Alexeff
