Abstract
The invention addresses the problem of providing a warp knitted fabric manufacturing method capable of stably producing a warp knitted fabric wherein the longitudinal stretchability is 200%. To solve the problem, the invention is a warp knitted fabric manufacturing method that forms bands of a warp knitted structure with increased longitudinal stretchability by forming stitches with an elastic warp (2) while knitting in an elastic inserted yarn (3) in the warp direction and knitting in the weft (4) in the course direction, wherein: active feed means (30), which are obtained by placing a single follower roller (323) above two drive rollers (321, 322), are disposed on the respective paths of the warp (2) and the inserted yarn (3) to feed the warp (2) and the inserted yarn (3) to the warp knitting machine while increasing the respective elongation percentage. The active feed means (30) keep the respective feed rates of the warp (2) and the inserted yarn (3) constant while feeding same to the crochet warp knitting machine (40).
