ABSTRACT:
A stretchable warp knitted fabric comprising warp knitting yarns, first weft in-laid yarns and second weft in-laid yarns, and stretchable warp in-laid yarns. The second weft in-laid yarns consist of a plurality of at least non-stretchable yarns, and said second weft in-laid yarns run sequentially and separately in the course direction on different wale regions of the same course with having an arbitrary length respectively, while crossing the first weft in-laid yarns between courses. Consequently, even when pulled in a longitudinal direction, because the separate second weft in-laid yarns influence each other independently, the fabric does not have a great amount of ruffling in a width direction thereof and thus the a flat surface is maintained wherein there is no narrowing in the middle of the longitudinal direction.
