Abstract: The denim industry's substantial environmental footprint, marked by high resource consumption and waste, has catalyzed the shift toward sustainable practices. Mechanical cotton recycling presents a viable, eco-friendly solution by reintegrating waste into the production cycle. This review critically examines the primary obstacle to its widespread adoption: the degradation of fiber quality during processing, which compromises yarn and fabric integrity. We synthesize and evaluate current strategies to counteract this issue, including optimized blending with virgin fibers, targeted chemical enhancements, and advancements in processing machinery. Furthermore, the paper highlights the synergistic role of industry-wide initiatives and emerging technologies in elevating the quality of recycled cotton. The findings underscore that a multi-pronged approach, combining technological innovation and collaborative action, is essential for advancing a circular economy in the denim sector.
