Abstract:In order to meet the market demand for alternate segment colored yarn，the alternate segment colored yarn is spun on the rotor spinning machine with black and white viscose based on the rotor spinning double carding spinning technology.The test plan is set by analyzing the spinning mechanism，and the influence of the rotor diameter，twist，rotor speed and carding roller speed on the yarn length and breaking strength of the transition section is analyzed by acquiring image of yarn appearance and comparing test data.The results show that the yarn appearance color in the transition section is roughly a gradual transition from black to white；the yarn length of the transition section is mainly concentrated in one to two times of the circumference of the rotor，and the larger the rotor diameter，the longer the transition section length；the breaking strength of the yarn in the transition section is less than that of the pure spinning section，which is the weakest position of the yarn；the breaking strength of the yarn in the transition section increases and then decreases with the increase of twist，rotor speed and carding roller speed.
Key Words:rotor spinning；double carding；alternate segment colored yarn；viscose；breaking strength；transition section；twist；rotor；carding  roller
