Programing mechanics in warp-knitted spacer materials with double inlay-jacquard systems

This paper focuses on programing mechanics of patterned spacer materials with double inlay-jacquard systems. Because of quite complex warp knitting paths and jacquard principles, an in-depth research on this double-jacquard techniques is conducted and then this paper proposes separate programing models of jacquard loop and jacquard underlap for the first time. Also, it studies a mapping method between the jacquard patterns design and colored loops formation process to automatically transfer what you design and see into what you knit. For the deviation between the design and the knitting result generated during the mapping process, an automatic detection method and an automatic correction algorithm are designed to ensure the accuracy of the mapping model. To comprehensively verify the programing model, an experimental design is exampled and then transferred into knitting parameters based on the programing system to fabricate a corresponding patterned material. This researched programing method shows great potential in increasing design efficiency and decreasing chemicals consumption in printing.
