纬编绕经织物设计与三维仿真

Design and 3-D simulation of weft knitted wrap fabric

为实现纬编绕经织物的设计与三维仿真,构建了花型意匠图模型、组织意匠图模型,并通过二者之间的变换关系得到织物的编织动作矩阵模型,将织物结构数字化存储。在深入研究这类织物结构特点的基础上,建立了织物理想状态下线圈结构的基本模型,确定了线圈中各型值点的位置,在Visual Studio平台上利用WebGL技术进行编程,实现对各类纬编绕经织物的仿真。此方法可有效解决此类织物因设计复杂暂未能系统实现设计仿真的问题。结果表明通过该方法可减少设计难度,得到较好的外观模拟效果,弥补了纬编绕经织物设计方法复杂、设计周期长、生产效率低的不足,拓宽了纬编绕经织物的市场应用。

In order to facilitate the design and three-dimensional simulation of weft knitted wrap fabric,the pattern model and the structure model were constructed,and the knitting action matrix model of the fabric was obtained through the transformation relationship between them,and the fabric structure were digitally stored.Basis on in-depth study in the structural characteristics of this type of fabric,the basic model of the loop structure in the ideal fabric state was established,and the positions of various value points in the loop were determined.Using WebGL technology for programming on the Visual Studio platform,the simulation of all types of weft knitted wrap fabrics was performed.This method led to the systematic design simulation of such fabrics effectively despite the design complexity.The results show that this method can reduce the design difficulty and achieve better appearance simulation effect.It overcomes the shortcomings arising from the complex design method,long design cycle and low production efficiency of knitted wrap fabric,and promotes the market application of knitted wrap fabric.
