Effect of laser engraving and cellulase enzyme treatment on jeans trousers

Abstract

A new trend of jeans trousers fashion is giving faded and worn out look to new jeans trousers for attracting the attention. In this study, effect of CO2 laser engraving and cellulase enzyme together were studied on the tensile strength of denim fabrics of jeans. This study detected which the best sequence of processes for treating jeans trousers. Different samples of denim trousers were engraved by CO2 laser at different laser power and resolution before and after cellulase treatment. Then the tensile strength of all samples was measured. This study concluded that, Co2 laser engraving process after cellulase treatment in high laser power is more suitable for denim fabrics. This sequence of processes decreases the loss of tensile strength of denim fabrics and save fabrics from damage. This study concluded that the loss of tensile strength by laser engraving in high laser power, more than the loss of tensile strength by cellulases treatment. So, when samples were treated by laser engraving in high laser power before treated by cellulases enzyme, that caused more damage for denim fabrics.
