Sustainability is the world's most requirement at the present world. Production and processing of sustainable textiles not only help to reduce the negative impacts on the environment, but also support millions of workers to earn fair wages and ensure proper working. In this study, the collected knitted waste fabric was categorized according to color and then this fabric was converted to recycle fiber. This sustainable fibre (SF) was mixed in different rations with virgin Cotton (VC) fibre and produced 16Ne rotor yarn. The produced yarn quality was determined by comparing the yarn IPI, CSP, U% and H value with Uster Statistics 50% and control yarn quality. The sustainable yarn sample SYS 02 is better in comparison to the standard and control samples but its mixing ratio is 25% SF and 75% VC. Itís not cost-effective for yarn production in bulk conditions. But the SYS 03 would be recommended due to its cost-effectiveness and its quality IPI 186, CSP 1350, U% 11.36 and hairiness 6.27 is better in comparison to the standard (Uster Statistics 50%) and control sample CYS 01. So, this produced sustainable rotor yarn is suitable to use in Denim industry where the yarn CSP is important. This sustainable yarn added the value of knitting waste as well as save the environment from unplanned landfilling.
