Abstract:

The 3-D simulation simulation technology of weft knitted fabric and its development history are systematically introduced. The challenges, recent research hotspots, and future development trends for 3-D simulation of weft knitted fabric are also detailed analyzed. According to the analyses above, some guidelines for the further research of 3-D simulatio are given. In this work, the research history of weft knitted 3-D simulation technology is discussed from three levels which are loop model, yarn realistic and mechanics simulation.  As years of research by scholars both domestic and overseas, the 3-D simulation has been develobed from static simulation to mechanics simulation with physical property. And the advantages and disadvantages of existing research results are analyzed. On this basis, the development trend of this technology is analyzed. The 3-D simulation technology will have a good development in physical simulation method, divwrsity of loop type and application scope diversification.
