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 its one longitudinal edge by utilizing single thread chain stitches formed with a monofilament thread having a coefficient of thermal contraction. The sewing thread has 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 adjacent two of the fastener elements, as viewed in a direction perpendicular to the general plane of the tape. The monofilament thread, after sewn to the tape, is heat-set to shrink and then become dimensionally stable, thereby holding the fastener elements more tightly on the tape. |
