Abstract
The study focuses on laser and ozone treatment processes on the physical and mechanical performances of two varieties of denim fabric: pure cotton and cotton/hemp fabric mixtures (50:50). The research takes a look at the possibility of such green finishing techniques that may minimize water consumption and environmental burden without compromising or improving the fabric quality. The denim samples were subjected to laser fading and ozone bleaching as two major treatment methods and in different concentrations and happy durations.
This test determines the tensile strength, tear strength, color fastness (washing, light fastness and crocking) and general visual appearance of the fabric treated. The outcomes indicate that laser and ozone therapies both lead to successful fading, and the laser treatment offers high precision, whereas ozone treatment is gentle and does not cause large damage to fibers. As compared to 100 percent cotton denim, where the fading effect was uniform, the 50/50 blend (cotton/hemp) material showed greater strength retention and more durable finishing when treated with ozone.
The study will help to design and perfect greener methods of making denims and imply that hemp fibers can complement the durability of denim fabrics and make them more sustainable when subjected to innovative solutions. The results also assist in understanding how to improve conditions of treatment both aesthetically and practically, and this works in the favor of textile industry towards the ‘greening’ of its activities.
