Latest Patents

Shinji Imai holds a patent for a coil-type slide fastener. This invention involves a core cord inserted into coil-shaped fastener elements made of thermoplastic resin. The fastener elements are sewn onto a fastener tape using a multi-thread chain stitch. The looper thread, primarily made of thermally meltable synthetic fiber, is utilized, while a less meltable fiber is used for the needle thread. The design ensures that the entangling points of the threads are strategically placed on the core cord. By thermally melting the looper thread, melted portions are formed at the entangling points, which enhances the attachment of the fastener elements to the tape. This innovative approach prevents the cutting of sewing yarn due to slider movement, resulting in an abrasive-resistant slide fastener.
