Abstract: According to the warp knitted jacquard seamless shaping fabric’s characteristics, this paper raises the fabric design model of combining lapping movement and jacquard grid to design this type of fabric by CAD; based on the intensive study of the warp knitted jacquard seamless shaping fabric’s structure characteristics, the loop structure theoretical simulation model is set up; in the loop excursion hypothesis of regarding loop root as deformation centrostigma, the paper makes a deep theoretical analysis of the jacquard seamless shaping fabric deformation which is caused by yarn tension. Combining with the fabric design model, loop simulation and loop deformation, using VC++.net for program design, it has successfully realized design and simulation of the jacquard seamless shaping fabric audio-visually and rapidly.

Key words: warp knitting, jacquard seamless shaping fabric, loop structure, design, simulation
