Research And Application Of Warp Knitted Broche Jacquard Technology

Among the current warp knitting technology, the development of Piezoelectric CeramicJacquard is very rapid and is more and more wildly applied into different kinds of warpknitting machines and its production. In addition, its combination with single-yarn selectionmechanism (EFS) forms a brand new warp knitting broché jacquard technology whichperfects the existing technology. At the moment, since the relevant research is not muchstudied and its practical utilization is usually restricted by technological bottlenecks, thispaper will focus on this new technology and its application.This paper firstly explores the principles of warp knitting broché pattern, the workingtheory of Jacquard system and its effects. Furthermore, this paper analyses both mechanicalconstitution as well as needle-select principles of single yarn select system and itsimplementation procedure of the selection. Thereby, the illustrated single yarn model is builtto clarify its detailed methods of the selection. Based on this analysis, this paper studies theweaving theory and procedures of broché jacquard fabric and thus summarizes itscharacteristics and advantages in weaving theories and fabric’s performance.Second, the text makes a research on the vital technology of warp knitted brochésystem or called single-yarn selection mechanism, provides the specific technology road tosingle-yarn selection mechanism and does the deep researchon the principal organ ofsingle-yarn selection mechanism including selection mechanism、trimming mechanism andsuction institutions. On the base of grasping the working technology of all parts institutionand its working requirements or the functions which is wanted to be realized, make a researchin technology aspect to set up the performance curve model of main movement mechanismand make an analysis on the labor discipline to extract technical parameters and technicalrequirement.Eventually, this paper analyzes the organizational structures and processes of brochéjacquard fabric and discusses its possible organizational structures. Not only have warpknitted weft insertion and its jacquard effects studied, but also have the most suitable yarnstructure for broché jacquard fabric explored. Furthermore, a research on its effects andcorresponding process has also been considered. Therefore, the author aims to design ideasand methods of broché jacquard fabric offering the methods of fabric design, especiallypresenting two different theories, methods as well jacquard fabric applications. As a result, animproved design theory of broché jacquard fabric will be applied into production.
