ABSTRACT:
The present invention provides a slide fastener which can exhibit a clear retroreflective phenomenon by providing retroreflective functions to filament fastener element rows and mounting threads. The retroreflective filament slide fastener of the invention includes filament fastener element rows formed from wire rods made of thermoplastic resin which have retroreflective layers formed by covering surfaces of the filament fastener element rows with retroreflective paint. A synthetic fiber thread is used as the mounting thread for mounting the filament fastener element rows to a fastener tape. The mounting thread is provided with a retroreflective layer by covering a surface of the synthetic fiber thread with the retroreflective paint, or winding or twisting a retroreflective film around or together with the synthetic fiber thread. Thus, the filament fastener element rows and the mounting thread which are the most conspicuous in the slide fastener can easily exhibit the retroreflective phenomenon.
