Abstract:

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.
