In this paper a mathematical model of looped warp knitted jacquard fabric is proposed. The technology parameters cover chain notation, threading, jacquard pattern grid and so on are defined based on the matrix. A basic pattern matrix is derived from chain notation and threading using the block matrix. Then combined with the displacement data of jacquard girds, the jacquard pattern matrix is calculated. Finally, the stitch type and stitch position are obtained analyzing the pattern information in the previous matrix. Special stress is laid on the difference between two different displacement data of jacquard girds, RT = 0 and RT = 1, which results in inconsistent lapping for the same jacquard bitmap. The pattern models are implemented and the jacquard lapping bitmap and three-dimensional simulation are generated by a calculating program via Visualstudio2015 using C# and JavaScript. The results show that this model can distinguish two types displacement jacquard information. The parameter input process is simplified and the run time for calculation is also shortened. In addition, with the help of CAD system via the web, priorities including resource sharing, design-time saving, and efficiency improving are achieved.

基于纤网的环经针织提花织物的搭接建模

本文提出了毛圈经编提花织物的数学模型。技术参数包括链记法、穿线、提花花样格子等都是基于矩阵定义的。基本模式矩阵是从使用块矩阵的链符号和线程中导出的。然后结合提花格子的位移数据，计算出提花花样矩阵。最后，通过分析先前矩阵中的图案信息，获得针迹类型和针迹位置。特别强调了两种不同的提花网格位移数据RT = 0和RT = 1之间的差异，导致同一提花位图的搭接不一致。使用C#和JavaScript通过Visualstudio2015计算程序实现花样模型，生成提花搭接位图和三维模拟。结果表明，该模型可以区分两种类型的位移提花信息。简化了参数输入过程，缩短了计算运行时间。此外，借助网络 CAD 系统，可以实现资源共享、节省设计时间和提高效率等优先事项。
