Effect of Laser Treatment on Pigment Printing on Denim Fabric - A Study of Colour Properties

In this study, denim fabric samples were pigment printed with and without laser treatment, the two commonly used methods in textile and fashion industry for adding colour effect to denim fabric. Various pigment printing and laser treatment parameters were used and their relationships with final colour properties of the denim fabric samples were investigated. After the treatments, colour properties of denim fabric samples were evaluated by CIE L*, CIE a*, CIE b* and CIE Delta E values. Experimental results revealed that lightness (CIE L* value) of denim fabric samples was affected by the mesh count, laser intensity and the sequence of applying pigment printing and laser treatment. It was found that a redder (evaluated by CIE a* value) and yellower (evaluated by CIE b* value) denim fabric samples were produced by applying laser before pigment printing.

Automated summary

This study compares the effects of pigment printing and laser treatment on color properties of denim fabric. Various parameters were used and their relationships with final color properties were investigated. The results showed that laser treatment sequence and intensity have an impact on the brightness and hue of the denim fabric.
