Our experiments show that the laser fading process has similar, even better results, in some
cases, than the conventional technologies of indigo-dyed denim. Using the beams from Nd:
YAG laser (1064nm and its second harmonic 532nm), CTH: YAG laser (2.09 μm), CO2 laser
(10.6 μm) and various laser beam parameters we found the optimum fluence and power
density in order to obtain a similar fading appearance like the one obtained by conventional
processes. The purpose of this work was to determine the effectiveness of laser-based …
Our experiments show that the laser fading process has similar, even better results, in some cases, than the conventional technologies of indigo-dyed denim. Using the beams from Nd:YAG laser (1064nm and its second harmonic 532nm), CTH:YAG laser (2.09μm), CO2 laser (10.6μm) and various laser beam parameters we found the optimum fluence and power density in order to obtain a similar fading appearance like the one obtained by conventional processes. The purpose of this work was to determine the effectiveness of laser-based technologies and to measure the wear characteristics of the processed textile like colorfastness, strength resistance, tearing strength, and dimensional changes.
