  • Heterofilaments for cord reinforcement in rubber goods
    Patent number: 5744237
    Abstract: In an improved power transmission belt, the circumferentially disposed reinforcing cords are made from multi-filament yarns of heterofilaments. These cords, when fused, have good inter-filament bonding without the solvent of the solvent/adhesive systems.
    Type: Grant
    Filed: June 10, 1996
    Date of Patent: April 28, 1998
    Assignee: Hoechst Celanese Corporation
    Inventor: Harry W. Stanhope

  • Process for spiral wrapping reinforcement filaments
    Patent number: 4607481
    Abstract: There is disclosed an improved feedstock package for a spiraling machine. The package comprises filamentary yarn having a twist of less than 5 tpi wound around a king spool. In contrast to prior art cone packages, the invention significantly reduces package distortion and threadline breakage in high speed spiraling operations employed in, for example, making reinforced plastic hose. Preferred embodiments include the yarn being greige yarn and the package rotational speeds on the spiraling machine being at least 1,400 rpm.

  • Process for bonding polyester reinforcement elements to rubber
    Patent number: 4462855
    Abstract: Polyester reinforcement fibers are treated to improve adhesion to rubber by applying a dissolved aromatic urethane coating to the fibers followed by coating the fibers with a resorcinol-formaldehyde latex and then heating the fibers sufficiently to convert the aromatic urethane to an aromatic isocyanate and applying to and curing a layer of rubber on said treated polyester fibers.
