The environmental load problem of the cotton fiber such as amount of water and pesticides used in the agricultural sector, the main raw material of the textile and apparel industry, obligates the extension of the fiber's life cycle. In order to ensure the sustainability of resources, efficient use of natural supplies and evaluation of recyclable wastes are required. However information lacking is the one of barriers in recycling and processing of cotton. In this study, open-end rotor yarns (OE-Rotor) were spun from the blends of recycled cotton fibers obtained from pre-consumer cotton products (r-CO) and the virgin cotton (C) fibers with 50/50 % ratios. The effects of production parameters (rotor type, navel type and torque type) on yarn properties were examined. According to the results the effect of the production parameters on all measured yarn properties except tenacity values, is statistically significant. It was concluded that %50/50 r-CO/C open-end rotor yarn samples producing by rotor type with narrowest groove, spiral navel type without notch and green torque type without twist stopping effect, led to lower unevenness, hairiness, IPI and higher breaking elongation.
