  Abstract

As global demand grows for sustainable textile materials, poly(L-lactic acid) (PLA) has emerged as a promising biodegradable alternative to conventional synthetic fibers. However, its inherent thermal sensitivity and structural instability during post-processing have limited its practical applications in apparel and functional textiles. This study investigates a batch-type, tension-free heat setting process aimed at improving the structural stability, mechanical integrity, and dyeability of PLA fabrics under controlled thermal conditions. Through a comprehensive evaluation of thermal, structural, and surface properties, the study identifies a temperature range that offers improved performance without compromising fabric softness. These findings provide valuable insights into the optimization of eco-friendly finishing processes for PLA textiles and contribute to the broader advancement of sustainable fiber technologies in the textile industry.
