Abstract:

In order to achieve the CAD for the leno color effect, this paper analyzed the forming principle of leno color effect firstly. It shows that the appearance of the color effect is not only changed by weave diagram and the order of colored warp and weft, but also by leno heddle lifting plan. So during the modeling process, the leno color effect is divided into weave diagram, order diagram of the colored warp, order diagram of the colored weft and leno heddle draft. The corresponding matrixes are set up. At the same time, using the Kronecker-product algorithms, we propose a mathematical model for the ordinary weave color effect. On the basis of the above works, the mathematical model for the leno color effect was established. Then we demonstrate the correctness of this model. This model provides a theoretical reference for the CAD system of leno weave.
