摘要为填补低纤涤纶长丝FDY20D24f加弹网络一步法工艺空白,介绍了K5118型加弹网络机的主要技术参数及加弹网络一步法工艺,并以涤纶长丝FDY20D24f丝条为例进行了实地工艺理论试验和核心工艺参数分析。指出:经加弹网络工艺加工的FDY20D24f长丝丝束平滑、富有弹性和规律网络风格;但由于假捻器转速、网络喷嘴孔径限制,生产效率低、耗气成本高,制约了技术发展;提出了袖珍型摩擦式假捻器的设想。

Abstract: In order to fill the vacumn of the one-step process of the draw texturing network in manufacturing low PET filament FDY20D24f,introduction is made to the main technical parameters of K5118 DTY machine and the one-step process on DTY network. Sampling the FDY20D24f PET yarn, the field process theory test and core process parameters are studied. It is pointed out that the texturing network processing of the FDY20D24f filament is of  smooth tow, good elasticity and regular network style. Due to the false twist speed and network nozzle aperture limit, cost efficiency is low and gas production is high, consequently restricting the development of technology. An idea of pocket friction type false twisting device is put forward.
Key Words: low PET filament; texturing network one-step process; process parameter; hot setting; texturing; network; false twist; false twister; the nozzle diameter
