Abstract:

To realize high-efficiency design of warp-knitted double jacquard shoe-uppers, based on the analysis of double jacquard shoe-uppers’ structural features, this paper analyzed its forming and jacquard principles, and established the computer-aided design model of this fabric. A mathematic model was set up for describing chain notations, threading-in design, jacquard grid and jacquard chain effect to conduct computer software to design warp-knitted double jacquard shoe-upper. Combined with the sport requirement s of human feet and production practices, the upper partition design and shoe jacquard pattern design and process design methods were introduced, and the design and process of this kind of fabric were summarized. The computer-aided design of double jacquard shoe-upper has been proved more rapid and accurate．
