ABSTRACT:
A slide fastener includes a row of coupling elements secured by sewing stitches to one longitudinal edge of a support tape made of a fabric material free of threads woven or knitted together. The sewing stitches are formed of at least one thread having loops passing through the support tape. The thread is made of a monofilamentary material which is free from thermal deformation. The slide fastener can retain, after heat-set treatment, sufficient mechanical strength at the connection between the sewing stitches and the row of coupling elements.
