基于气流/环锭联合加捻的一次成型股线纺纱工艺研究

Spinning craft of once sharped folded yarn based on air spinning combined with ring spinning

为了一次成型得到股线,节约工厂的生产成本,减少劳动力,在环锭纺的基础上,结合喷气涡流纺和赛络纺工艺,仅通过一套细纱系统使粗纱一次成型得到股线。这种纺纱方式结合了3种纺纱工艺的优点,具有非常广阔的市场前景。研究了新型复合纺纱工艺的纺纱原理以及工艺参数对成纱力学性能的影响等,最终得到目前的最优生产方案为：粗纱定量2.5 g/10 m、捻度1 250捻/m、气压0.15 MPa。

In order to get the once-shaped folded yarn, save the factory production cost and reduce the labor force, based on ring spinning combined with air-jet vortex spinning and siro-spinning, a once-shaped folded yarn can be produced just by one spinning system.This kind of spinning method combines the advantages of three kinds of spinning processes, and it has a very broad market prospect. Theprinciple of new composite spinning process and the process parameters which influence the mechanical properties of the folded yarn arestudied. Finally, the current optimal production scheme is obtained, that is roving weight 2.5 g/10 m, twist 1 250 t/m and air pressure 0.15 MPa.
