Abstract:

In order to simulate and virtually display the few-guide bar yarn dyed fabrics, and analyze the knitting principle and the structure characteristics, based on the measurement and analysis of the actual stitch size, geometric models for stitches were established. Matrices for coordinates of stitches and transformation were adopted to obtain the stitch coordinates of the whole fabric according to the chain notation. Double buffer technology in the Web software was used to store the canvases with stitches and underlaps, which were superimposed together to implement the simulation. The pattern texture was captured as a screenshot, which was displayed on garment models by texture mapping. The simulated results were validated by comparing bitmaps of the real fabrics and the simulated ones. This research indicates that the method adopted is able to precisely simulate the pattern and size to achieve the visual design and display.

Key words: few-guide bar yarn dyed fabric, geometric models for stitches, garment virtual display, knitted fabric simulation
