Technique And Simulation Of Warp Knitted Broché Fabric

The paper mainly studies up on the technique and simulation of warp knitted brochéfabric, and discusses the application of a system based on the pre-studies, that is the technical design and fabric simulation of the brochéfabric.The warp knitted brochéfabric, also named Cliptronic? fabric,which is produced by one of the jacquard-raschel machines based on the application of piezo jacquard system(PJS) and single-end selection device(EFS), has special tri-dimensional brochépattern motifs positioned on the light and delicate ground anywhere. It has excellent and specific characteristics of warp knitting fabric, as well as embroidered look. And it is similar with the slap-up cutting pattern in fashion. The EFS worked with JB1.1 ensures a relief-like embroidery effect in the jacquard pattern, by taking out the brochéyarns from the knitting process and by interlacing them later on. In this process, the cutting bar cuts out the useless brochéyarns.After analysis of brochéfabric and experimentations, the paper studies the basic principles to form this specific fabric, and mainly discussed the technique and simulation module, concluding of the technical design of pattern motifs, as well as the transforming rules of jacquard design data from pattern motifs to warp knitted brochépattern motifs. At last, technical design and simulation modules are appended successfully in the WKCAD3.0 based on the Visual C++.NET 2003, as well as the control data output for produce knitting.And about the technical design, it's just need draw the pattern motifs, WKCAD3.0 intercalated beforehand to transform it automatically to warp knitted brochépattern motifs. So that, simplified the colors choosing and saved time drawing, and at last it's for the benefits of company, who can get the new production in a very short of time efficiently.Considering the influence of yarn tension and so on, achieves the true to life simulation to get a review of finished fabric when carry through the technical design drawing, no need to trial knit on the machine.At the same time, the series of machine have their special and separate use to cater for the various needs of different customers,It's meaningful of research and development for the market needs.
