TRANSVERSELY STRETCHABLE STRINGER TAPE FOR SLIDE FASTENERS

摘要

A warp-knit stringer tape, for slide fasteners, including a pair of transversely non-stretchable longitudinal edge portions and a transversely stretchable intermediate portion extending therebetween. The stringer tape has a knit ground structure composed of chain stitches and tricot stitches. At the stretchable intermediate portion, the tricot stitches are formed of a plurality of elastic yarns such as stretch yarns, while the chain stitches are formed of a plurality of non-elastic yarns such as multifilament yarns. At least one elastic weft yarn is laid in the knit ground structure at the stretchable intermediate portion.
