  • Publication number: 20240000198
    Abstract: A polyester woven-fabric hook-and-loop fastener has a warp yarn thickness Tb which is 0.94 times or less of a warp yarn thickness Ts. A selvage area having a constant width is present on two opposite ends, continuously in a line form in the warp direction, without misalignment in the weft direction. As a result, when the polyester woven-fabric hook-and-loop fastener is sewn onto a garment or the like, a sewing thread sewn to the selvage area is in a straight line without meandering, and thus a sewn product excellent in appearance can be obtained.

  • Patent number: 10252499
    Abstract: A process includes forming a transfer film without a release layer in which the transfer film includes a substrate layer to be peeled off during a transfer process, and a transfer layer to be transferred to an article to be decorated. The transfer layer has a protective layer, a printed or vapor-deposited decorative layer, and an adhering layer, which are laminated in this order. The substrate layer is a base film of a synthetic resin formed by extruding a molten synthetic resin. The substrate layer is so laminated and thermally compressed in direct contact with the protective layer such that the substrate layer does not peel off the protective layer before the transfer process and peels off the protective layer from a peeled end portion of the substrate layer as a trigger during the transfer process, by thermally pressing the substrate layer and the protective layer between rolls.
