Abstract:

In view of the complex 3-D simulation of warp knitted fabric, the software of TexGen, mainly used for 3-D simulation of woven fabric, is used to solve the problem. Based on the geometric modeling of TexGen, firstly, the yarn’s 3-D centerline is described by specifying a number of discrete positions along the yarn length of the unit cell. Secondly, interpolating is defined by sweeping a simple two dimensional shape along the length of the yarn; and finally, the unit cell is repeated to form the 3-D warp knitted fabric. The results show that TexGen is simple and workable to simulate the warp knitted fabric in 3-D, and as shown in the simulated graphics of warp knitted fabrics, the loops and the links between loops are smooth, which gives a good simulation.
