The laser fading process is acknowledged as a very strong alternative compared to the conventional physical and chemical processes used for aged-worn look on denim fabrics. In this study, the beams from a CO2 (10.6 µm) laser was used for the fading of denim fabrics. The effects of laser beam on the physical properties of denim fabrics such as tensile strength, tear strength, abrasion resistance, and static and kinematic friction coefficient were investigated and optimum process conditions were determined. In order to investigate the effect of laser fading treatment on colour change, the fabrics were washed and colour efficiency, L a b values and yellowness index were measured after washing process. In terms of both colour and mechanical properties, it is found that 100 and 150 μs pulse times are suitable for laser fading process of denim fabrics.
