Design of Warp-Knitted Single/Double Jacquard Fabric for Shoe Vamp

Abstract

Abstract In order to address the problem of the scarce stitch and color of conventional warp-knitted jacquard fabric, this paper puts forward a method of knitting single/double jacquard shoe vamp fabric with a multiple pattern and color on a high-speed warp knitting jacquard machine. In electronic jacquard systems, lateral movements of jacquard bars, relative to the needle bar, combined with controlled stitch structure and displacement data, facilitate the formation of loop and double loop stitches. And two split jacquard bars in half-gauge in odd and even wales can be threaded in yarns with different colors or varied dyeing performances, then the two-color jacquard effect can be obtained combined with stitch structure design. Taking the specific process as an example, this paper introduces a process design method for single/double jacquard shoe vamp materials, including raw material selection, stitch design, jacquard design, process parameter design, textile finishing design, et al., which can provide a theoretical foundation for the design and development of other warp-knitted jacquard fabrics.
