Abstract: According to 3×3 plain’s characteristics of simple, equilibrium and symmetrical weave points, its fractal weave with four levels of self-similar structure is drawed by using L-System chain-languages and computer graphics techniques, on which some main changing forms of its fractal weave are investigated for design application. The methods are specially studied to obtain a new type of weave structures with variations of filling-weave based on 3×3 plain’s fractal weaves, and the research focuses on the basic approaches to generate a new fabric surface and texture by design. At the same time, the initial effort is made for applying the L-system fractal theory to design a new type of fabrics with some jacquard weaving experiments.
