Construction of the 3D Model of Three-guide Bar Warp-knitted Fabric for Automotive Interiors Use
For the complex three-guide bar warp-knitted fabric,the Rhino modeling software was used for 3D modeling of geometry of warp-knitted fabrics.Firstly,based on the principle of NURBS curve,the overlap and underlap of the three-guide bar warp knitted fabric were modeled separately,and the yam center curve with high spatial position accuracy was obtained by determining the curve control point fitting.Secondly,the 3D modeling of each group of loop unit cell model was scanned according to the yarn diameter,and the complete fabric model was assembled.Finally,according to the loop trajectory of the fabric,the curve equations for the warp-knitted fabric were obtained.The results show that it is simple and feasible to use Rhino modeling software to construct the 3D model of warp knitted fabric,and the loops are tightly intermeshed and do not interfere with each other,which can achieve a good fabric effect.
