Abstract: This paper studies the new three-needle jacquard principle and analyzes its 16 kinds of laying effect. By utilizing its rich stitch changes and making some improvements to the conventional 22-needle jacquard warp-knitting machine, the warp-knitted jacquard fabric can show the flyknit effect. Applying this effect to the vamp design can form a new style, providing new ideas for the product development of warpknitted jacquard vamp.
