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 CO 2 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 CO 2 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, Co 2 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.
Cellulase enzyme Reactive dyes Cotton Knitted fabrics Children's wear Interlock Single jerseyThis paper studied the influence of cellulase enzyme on some physical and mechanical properties of two kinds of cotton knitted children's wear (single jersey 100% cotton T-shirt, interlock 100% cotton T-shirt). Samples of garments were dyed with reactive dyes, then treated with acid cellulase enzyme according to standard conditions. Some physical and mechanical properties were measured, then compared these properties before and after cellulase treatments. Cellulase enzyme treatment improve some mechanical properties of cotton knitted wear such as pilling resistance and water absorbency. Cellulase enzyme treatment decrease some properties of cotton knitted wear in acceptable rate such as fabric weight, fabric thickness, fabric burst resistance, and seam tensile strength of T-shirt side seam. The influence of cellulase enzyme treatment on the most physical and mechanical properties of interlock 100% cotton children's T-shirt is better than its influence on the same properties of single jersey 100% cotton children's T-shirt.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
