Slide fastener made of synthetic resin

Abstract

Disclosed is a recyclable slide fastener having substantially all the component parts thereof made of the same type of synthetic resin material. In the fundamental embodiment of the slide fastener having a pair of fastener tapes and coupling elements fixed to the longitudinal edges of the fastener tapes, they are made of a synthetic resin material of the same type selected from the group consisting of a polyamide resin, a polyester resin, a polyolefin resin, and a vinyl chloride resin. When the slide fastener comprises sewing threads for the fixation of the coupling elements to the fastener tapes and/or core cords extended as inserted through the individual coupling elements, they are made of the same type of synthetic resin as the fastener tapes and the coupling elements. In the slide fastener of the type having upper and lower stop members provided respectively at the upper and lower ends of the rows of coupling elements or the open-link type slide fastener which has a pin-and-box separator and a pair of reinforcing sheet-like members fixed to the lower end portions of the fastener tapes, they are made of the same type of synthetic resin material as the other component parts mentioned above. Preferably the slider is also made of the same type of synthetic resin material as the other component parts mentioned above.
