<p>A slide fastener is disclosed which comprises a pair of stringer tapes of a warp-knitted structure including wales and fastener component parts attached to the tapes. These fastener component parts are made of a thermoplastic material and attached by injection, extrusion, supersonic or high-frequency heating to the stringer tape or tapes. The resulting tape or tapes are provided with the material of the fastener component parts extended into and through the interstices of the knitted structure and further into the wales so as to provide increased stability of the parts against displacement or detachment under severe stresses.</p> |
