Abstract: In this paper, B/S mode was selected to develop the Internet knitting CAD system. The users employ this system by accessing the site through the browser. This system was divided into the following three layers, design layer, data processing layer and data output layer. It is applicable to designing warpknitted, weft-knitted and flat-knitted fabrics with the six function modules, namely pattern design, process design, fabric analysis, fabric simulation, data output and product database. This system geared to the needs of the production process and had a complete product database. At the same time, it had the characteristics of simple pattern drawing, quick data processing and real fabric simulation, etc.

Key words: Internet; knitting CAD; simulation; database
