Investigation of the application angle and mode parameters on colour fading obtained in laser process

Abstract In this study, the effect of four factors affecting colour fading in the laser process (resolution in the X direction, resolution in the Y direction, pixel time and application direction/angle [56°, horizontal, vertical]) were statistically examined. Then, the effect of application direction/angle (56°, horizontal, vertical) and application mode (Normal, HDR Soft, HDR Medium) were investigated in more detail. It is believed that this study will contribute to the literature and is original since there is no study on the effect of application angle and/or mode during laser treatment. It was found that beyond the resolution and pixel time, application direction/angle and mode (HDR Medium > HDR Soft > Normal) are important in terms of colour fading for 11.25 ounce trousers made of 95.3% cotton/3.4% polyester (T400)/1.3% elastane used in this study.
