Abstract: In order to design weft jacquard terry fabrics rapidly and accurately，this paper is based on two-dimensional mathematical model of the matrix to describe this kind of fabric structure, which includes artistic conception drawing and knitting diagram, then we discuss its corresponding algorithm of translating pattern information to knitting information. According to the mathematical models and theories mentioned above, we invent a professional CAD system of designing weft jacquard terry fabrics autonomously under Visual C++ development environment, and we illustrate practical processing and operating methods in detail. As more performance optimizations being done on the mathematical models, we can further improve the design speed of these fabrics in the near future.

Key words: weft knitting, facquard plush fabric, 2-D matrix modeling, pattern, computer aided designing system
