3D simulation of warp-knitted double-needle bed creel jacquard fabric based on the stitch layer

Abstract

Unlike common jacquard fabrics, the warp-knitted double-needle bed creel jacquard fabric has more unique patterns, which allows to knit two-needle stitch structure on both ground guide bars and jacquard bars. It increases the pattern design complexity and has applications in many fields. However, due to the complex jacquard displacement signals and patterns, the actual patterns and structures remains elusive during the design process. Here, we propose a 3D (three-dimensional) simulation method for the warp-knitted double-needle bed creel jacquard fabric. The knitting parameters are established as mathematical models, by which the jacquard displacement signals can be simplified to numbers to combine with the basic chain notations. The spatial structure of the fabric is analyzed and a 3D stitch-layer model is generated. The simulation results show that through this modeling method, all stitches are arranged in an orderly manner at the appropriate layer, making the stitch position clearer and the 3D structure of the fabric easier to be observed.
