Abstract:In order to reduce the production cost，the technological process，each process configuration and quality control points of spinning OE 19.4 tex yarn taking 50% combed noil，43% combed cotton broken web and 7% 328 medium cotton as raw materials are described in detail.By setting different twist and tension in rotor spinning process，and comparing and analyzing the yarn index，yarn end breakage rate and cheese hardness，the appropriate twist and tension are optimized，and OE 19.4 tex yarn of good quality made of 56% combed noil and 43% combed cotton broken web is successfully produced.It is pointed out that when the twist is 138 twist/(10 cm)，the tension gear are 105 teeth and the speed ratio between drawing and winding is 1.04，the OE 19.4 tex yarn has good quality，the cheese feels soft and hardness is proper，and the loom efficiency reaches more than 80%.When raw cotton is not used in cotton assorting，the yarn index and loom efficiency have not changed much.Twist of rotor spinning fine yarn should be large under the premise of warping and loom normal production.
Key Words:combed noil；combed cotton broken web；rotor spinning；OE 19.4 tex；cotton assorting；twist；tension；loom efficiency
