ABSTRACT OF THE DISCLOSURE A slide fastener stringer includes a stringer tape having a pair of opposite surfaces, and a series of fastener elements sewn to the stringer tape on one of the surfaces thereof along one of its longitudinal edges by utilizing single thread chain stitches formed with a monofilament thread having a substantial coefficient of thermal contraction. The sewing thread having a succession of loops disposed on the other surface of the tape, each loop being intralooped with a preceding loop of the same thread such that the crossing of these adjacent two loops is disposed between a respective adjacent pair of the fastener elements, as viewed in a dir- ection perpendicular to the general plane of the tape. The monofilament thread, after being sewn to the tape, is heat- set to shrink and then become dimensionally stable, thereby holding the fastener elements more tightly on the tape.
