Abstract: The purpose of this paper is to quickly and accurately establish the overall orthogonal organization model and easy to expression orthogonal woven fabric interwoven structure. On the basis of analysis of the overall orthogonal structure features, five parameters such as fabric layers (warp layers+weft layers), the number of warp columns and weft columns, the number of stitching yarn and the way of stitching are proposed to represent the overall orthogonal organization. Assuming the form of warp, weft and stitching yarns in ideal orthogonal organization, using the giant element body, the yarn cross-sectional dimension calculation was established. The model of the yarn and the orthogonal organization cad design program is written in the development environment provided by UG/Open GRIP. The overall orthogonal organization model can be quickly and accurately established by entering the necessary parameters. The model is not only able to clearly characterize the structure of the fabric, but also to calculate fabric fibers volume content and the thickness of the fabric.

Key words: overall orthogonal organization, fabric structure, yarn cross-section
