The qualities of rotor spun yarn greatly depend on the fibre properties as well as processing parameters especially when the yarn is manufactured from 100% waste cotton. The purpose of this work was to observe the effect of the main vacuum pressure of the transfer channel and the additional suction pressure for the trash removal on the quality of rotor yarn produced from 100% waste cotton. Mixing of spinning waste and virgin cotton is a common phenomenon in the case of producing rotor yarn but yarn manufactured from 100% waste cotton is a very rare case. Very limited study has been performed in this research field. For that reason, the experimental work was done in order to observe the influence of main vacuum and additional suction pressure on the quality of rotor yarn manufactured from waste cotton. Quality parameters such as mass variation (CVm %), imperfection index, tenacity, and elongation of six 10Ne rotor yarn samples were investigated by varying different main vacuum pressure as well as additional suction pressure. The results revealed that 6kPa main vacuum pressure and 0.5kPa additional suction pressure were the ideal values considering the overall quality of yarn.
