A slide fastener stringer includes a stringer tape having a pair of opposite surfaces, and a series of fastener elements attached to the stringer tape on one of the surfaces thereof along its one longitudinal edge by use of single needle double locked stitches composed of a needle thread and a looper thread. The needle thread includes a monofilament yarn having a coefficient of thermal contraction, and the looper thread includes a spun or multifilament yarn. The stitching is accomplished from the tape side of the slide fastener stringer. The needle thread, after stitching is heat set to shrink it and make it dimensionally stable. |
