In this process the fiber sliver is separated into single fibers and in which the separated fiber material is brought by an air stream to a collecting surface from which it is drawn off while being twisted. It is a more recent method of yarn formation compared to Ring Spinning, the production rate of rotor spinning is 6–8 times higher than that of ring spinning. The yarn produced by the rotor spinning frame presents different features from the conventional ring yarns. The mainly material used for Open-end rotor spinning are cotton fiber and polyester fiber. The article presents the research results on physical characteristics of 3 types of 100% cotton yarns Ne10/1, Ne16/1 and Ne20/1 produced by open-end spinning at Eight March Textile Company Limited and Hoang Thi Loan company. The results indicate that the actual yarn’s count and yarn count’s unevenness of Eight March Textile Company Limited is smaller than that of Hoang Thi Loan company. Yarn twist of Eight March Textile Company Limited is smaller than that of Hoang Thi Loan company. Thin places (-50%/km), thick places (+50%/km), neps (+200%/km) and hairiness of Eight March Textile Company Limited is smaller than that of Hoang Thi Loan company.
