Sustainable fashion is a key driver in reducing environmental impact, and the integration of recycled materials into textile production presents a promising solution for high- performance apparel. This study focuses on the development of eco-friendly athletic gear by recycling cutting waste and eliminating the dyeing process, thereby reducing water and chemical consumption. Three fiber blends are evaluated for their potential in sustainable sportswear: 50% recycled PET + 50% recycled Modal, 50% recycled PET + 50% recycled Bamboo, and 50% recycled PET + 50% recycled Lyocell. Among these, the recycled PET + recycled Lyocell blend exhibits superior performance in terms of durability, breathability, moisture-wicking, and overall comfort. Lyocell’s natural hydrophilic properties, combined with the strength and recyclability of PET, result in a fabric with enhanced sweat absorption, quick drying, and excellent wear resistance. To further improve moisture-wicking and softness, the fabrics undergo chemical treatment with eco-friendly silicone. Performance evaluations, conducted using standardized ASTM tests, assess key attributes such as tensile strength, abrasion resistance, and long-term moisture management efficiency. The results demonstrate that the recycled PET + recycled Lyocell blend offers the most balanced combination of strength, sustainability, and wearer comfort, making it a highly viable option for next-generation eco-conscious sportswear. This study contributes to the advancement of sustainable textile innovations, promoting circular economy practices in the fashion industry while enhancing the functionality of performance wear.
