长丝超喂率对转杯纺复合纱外观与结构的影响

Influence of filament over-feed ratio on appearance and structure of rotor spun composite yarns

介绍了转杯纺复合纱的纺纱原理,并在经过改装的转杯纺纱机上,通过调整涤纶长丝的超喂率生产不同外观和结构的转杯纺复合纱。经纱线外观和结构的测试分析,表明长丝超喂率对转杯纺复合纱中长丝的几何位置和空间形态有显著的影响。

The spinning principle of rotor spun composite yarns was discussed and different kinds of rotor spun composite yarns with different appearance and structures were produced by combining staple fibers with filament yarns under varying filament overfeed ratio on a modified open-end rotor spinning frame. The effect of filament over-feed ratio on the appearance and structure of composite yarns have been studied. Results showed that filament over-feed ratio has great influence on the filament geometric nosition and helix traiectorv in comnosite vams.
