A research on the effect of various laser fading parameters on physical and surface properties of denim fabric

The purpose of this study is to investigate the effect of various laser processing parameters on the mechanical, air permeability, handle, and surface properties of denim fabrics. The parameters were chosen as laser resolution, laser density and the pixel time. In addition, the effect of washing cycle on laser faded denim fabrics was also examined. After laser fading and washing processes, fabric weight, air permeability, circular bending rigidity, bending length, coefficient of friction, tensile strength, tearing strength, and abrasion resistance of denim fabrics were measured. Furthermore, the colour differences between the unwashed and washed denim fabrics were determined and SEM analysis was carried out and the obtained results were evaluated statistically.
