Study on Physical Properties of Sustainable Eco Yarns

The burgeoning need for sustainability in textile production has encouraged researchers to explore innovative fiber blends that not only reduce environmental impact but also maintain or improve textile performance. In this study, sustainable yarns were prepared by blending conventional cotton with a range of novel fibers including lotus, smartcel, kapok, lenzing refibra, cupro, sarona, and aloevera. Comprehensive evaluations of the yarns physical properties such as tensile strength, elongation, unevenness, hairiness, and friction were conducted under standard testing conditions. Detailed testing methodologies were adopted employing state-of-the-art instruments including the Premier Tensomaxx, Uster Tester 6, and Reseda Friction tester. The study also included cotton blended yarns with other natural & regenerated fibers as control samples. Results indicate that Cotton/Lenzing Refibra (60/40) blend is the overall best for both quality and industrial processing. It provides the highest combined tenacity and CSP, guaranteeing strong, long-lasting yarn. Maintains balanced friction characteristics for efficient manufacturing. It is good balance between evenness (U%), low hairiness, and low-to-moderate imperfection index (IPI). Provides added value by virtue of being eco-friendly and containing recycled material (a leading trend in international textile creativity and supply chain sustainability). The implications of these findings extend both to industrial applications and future research into the development of high-performance eco-friendly textile material.
