运用喷气涡流纺技术生产桑皮纤维/棉55/4528 tex喷气涡流纺针织纱，通过多目标灰色局势决策方法对纺纱关键元件喷嘴和纺锭内径进行优选，确定最优的纺纱元件为5孔的喷嘴、1.3 mm的纺锭内径。采用正交试验设计方法,对喷气涡流纺的纺纱速度、喷嘴压力、前罗拉到纺锭顶端的距离等3个关键工艺参数进行优化设计，并得出喷气涡流纺的最佳工艺参数：纺纱速度为300 m/min，喷嘴气压0.6 MPa，前罗拉到纺锭顶端的距离为18 mm。

A 28 tex mulberry/cotton (55/45) knitting yarn was spun with air-jet vortex spinning technology. By using multiple objective grey situation decision model the key spinning elements including air-jet nozzle and spindle were selected and decided that the optimal ones are five-hole nozzle and spindle with 1.3 mm inner diameter. Three key parameters of air-jet vortex spinning process including spinning speed, nozzle pressure and the distance between nozzle and front drafting roller were also optimized by orthogonal test and the test results show that the optimal spinning speed is 300 m/min, the nozzle pressure is 0.6 MPa and the distance between nozzle and front drafting roller is 18 mm.
