一步法锦纶分纤母丝纺丝设备及工艺探讨

The Equipment and Process for One-step Spinning of Nylon Mother Yarn

文章介绍了一步法生产锦纶分纤母丝的纺丝设备及工艺特点,详细论述了螺杆挤压机、熔体管道系统、纺丝组件、冷却装置及牵伸卷绕机的设备特征。并以生产锦纶264 dtex/8 f的分纤母丝为例,探讨了锦纶分纤母丝的高速纺丝、牵伸-卷绕-热定形等工艺特点。

In this article, the characteristics of the main equipment and process for one-step spinning of nylon mother yarn are introduced, with the characteristics of the screw extruder, melt pipe system, spinning pack, quenching device and draw-winding machine introduced in details. By taking the production of the 264dtex/8f nylon mother yarn for an example, the features of high-speed spinning, drawing-winding-heat-setting processes are analyzed and discussed.
