[Abstract]:With the pursuit of portability, comfort, fashion and personalization of sports shoes, warp knitted Jacca fabric has become the first choice of sports upper material because of its rich color effect, excellent physical performance and high production efficiency. However, the traditional Jacquard fabric is mostly used in clothing, lacking the systematic research on the design, simulation and virtual display of Jacquard upper fabric. Focusing on the key technology of fast design and simulation of Jacquard upper fabric, the design and simulation model of Jacca upper fabric is established, which solves the difficult problems such as the design dimension can not be controlled, the simulation effect is poor, and the 3D virtual is lacking. The high efficiency design and 3D display of Jacca upper fabric are realized. The specific research contents are as follows: firstly, the structure characteristics and process principle of Jacca upper fabric are studied. According to the structural characteristics of Jacca upper fabric, this kind of fabric is divided into single layer structure Jacca upper, double layer structure Jacca upper and three layer structure Jacca upper. The structure characteristics and forming principle are analyzed in turn, according to the different Jacquard jacquard patterns, The principle of Jacquard co-directional jacquard, Jacquard reverse jacquard and double Jacquard jacquard is discussed, which lays a foundation for the design and simulation of Jacquard upper fabric. Secondly, the design method of warp-knitted Jacquard upper fabric is studied. This paper studies the pattern design method of Jacca upper, and puts forward the typesetting design method of parallel collocation and staggered collocation of upper. This paper probes into the method of dimension design of Jacca fabric, designs and tests from the aspects of machine density, structure and structure of Jacca fabric, summarizes the laws that affect the overall and local dimensions of Jacca upper fabric, and develops a dimension prediction system. Starting with raw material, structure, process parameters and finishing design, three kinds of Jacca upper fabric are put forward. Thirdly, the computer-aided design and simulation technology of warp-knitted Jacquard upper fabric are studied. The computer aided design model of Jacquard upper fabric was studied, including yarn movement, Jacca craftsmanship and warp design model. The simulation method based on spring-mass is deeply studied. The basic model of coil structure is established by geometric method. Combining with the physical properties of fabric, the coil is simplified to mass, the extended line is regarded as spring, and the internal force and external force are analyzed. The regularity of fabric deformation is analyzed, and the simulation of double Jacquard upper fabric is realized by program. Finally, the three-dimensional virtual display technology of Jacca upper fabric is studied. Three-dimensional shoe modeling, Jacquard upper fabric prototype modeling and three-dimensional virtual display were studied. Taking a typical sports shoe as an example, each characteristic point is determined and measured 3D coordinates are measured, and a triangulated mesh solid upper model is established. The simulated upper fabric is designed and simulated, and the 3D virtual display of the upper is carried out by OpenGL texture mapping technology. Finally, the VC programming language is used to realize the three-dimensional virtual display of Jacquard upper. The research provides a reference for the rapid design and simulation of warp knitted Jacquard upper fabric, which has theoretical significance and practical value.
