Sustainability and a green environment are international imperatives today to mitigate the environmental impact of numerous industrial sectors. The textile industry is among those most reliant on chemicals in its primary wet processing stages. Consequently, it necessitates innovative finishing techniques to enhance product quality and reduce environmental impact. The principal objective of this study is to examine the effects of chemical-free finishing and treatment processes on natural fibers and natural/synthetic fiber blends. Laser technology, as an example, has been employed in this work as a surface treatment method to enhance the dyeability of selected fabrics. Several laboratory tests were conducted to assess surface morphology, color depth, and dye stability following laser surface treatment. The results indicated a substantial improvement in dye absorption rates and an increase in dye stability against variables such as light, washing, and friction after laser treatment. This qualifies chemical-free treatment methods as an effective and sustainable alternative to conventional, chemical-based methods.
