Abstract:

In the present work, we propose a framework of simulating the colour appearance for weft-knitted fabric. A self-developed image capturing apparatus was used to record an image of coloured spun yarn. Pierce’s loop model was used for the colour mapping of weft-knitted fabrics. According to the algebraic-geometric relation of Pierce’s loop model, the colour information of the coloured spun yarn is mapped onto the loop. We found there exist „black spots” on the simulated needle loop and sinker loop due to the mismatch between the pixels of the yarn and the arc of the loop, which can be resolved by the interpolation fitting procedure. Moreover, changing the loop length offers a way to control the pattern of weft-knitted fabric. Finally, the brightness values at different positions of the loop were calculated in HSV color space to generate virtually realistic textures of the simulated weft-knitted fabric.
