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.

基于组织层的经编双针床筒子架提花织物3D模拟

与普通提花面料不同，经编双针床筒子架提花面料具有更多独特的图案，可以在地导杆和提花杆上编织双针组织结构。它增加了图案设计的复杂性并在许多领域都有应用。然而，由于提花位移信号和图案复杂，在设计过程中实际的图案和结构仍然难以捉摸。在这里，我们提出了一种经编双针床筒子架提花织物的 3D（三维）模拟方法。将针织参数建立为数学模型，将提花位移信号简化为数字，并与基本链符号相结合。分析织物的空间结构并生成 3D 缝合层模型。仿真结果表明，通过这种建模方法，所有的线迹都有序地排列在适当的层上，使得线迹位置更加清晰，织物的3D结构更容易观察。
