摘　　要：探讨BD448型转杯纺纱机工艺参数设计对C 27.8tex竹节纱效果的影响。优选竹节纱捻度和纺纱配件,对比分析花式化系数K_F、基纱前进步数S_1、竹节前进步数S_3等3个参数对竹节效果的影响规律。试验表明:花式化系数K_F值为15和竹节前进步数S_3值为10时竹节效果显著;基纱前进步数S_1和竹节前进步数S_3分别影响节距和节长,竹节前进步数S_3设定值要小。认为:通过工艺参数的优化,转杯竹节纱的竹节效果明显,更适合应用在针织纱领域。The influences of the processing parameter design on BD448 rotor spinning frame for C 27.8 tex slub yarn effect were discussed. The twist and spinning accessories of slub yarn were optimized. The influence principle of three parameters including fancy coefficient value KF, base yarn forward steps S1 and slub yarn forward step S3 on the slub effect were analyzed and compared. The test results show that the slub effect is obvious when the fancy coefficient value KF is 15 and slub yarn forward step S3 is 10. The slub gauge and slub length were affected by the base yarn forward steps S1 and the slub yarn forward step S3 separately. The setting value of slub yarn forward step S3 should be smaller. It is considered that the slub effect of rotor slub yarn is obvious through process parameter optimization. It is suitable for the application of knitting yarn field.
