高速纺丝交络一步法生产聚酰胺6poy/fdy复合纤维的设备

Abstract

The utility model discloses equipment for producing polyamide 6POY (Pre Oriented Yarn) /FDY (Fully Drawn Yarn) complex fibers for a high-speed spinning and winding one-step method. A cooling device comprises a slowly cooling device which is installed below a spinneret plate and a loop air blast cooling device is installed below a heater of the slowly cooling device, so that melt squeezed from the spinneret plate passes through the cooling device, the effect of reducing the trickle cooling rate of the melt is achieved, and cooling of yarn beams is uniform and consistent. An oil spraying device is installed below the loop air blast cooling device. A stretching thermal forming device and a guide yarn winding device are arranged in a parallel mode, the stretching thermal forming device is used for preparing polyamide 6POY fully drawn yarns, the guide yarn winding device is used for preparing 6FDY fully drawn yarns, and a winding mechanism combines the polyamide 6POY yarns and the FDY yarns in 4000 to 5000 meters per minute. The equipment for producing the polyamide 6POY/FDY complex fibers for the high-speed spinning and winding one-step method has the advantages of being short in production process, simple in working procedure, low in preparation production cost, low in energy consumption and high in efficacy and enabling products to be diversified in structure and good in quality.
本实用新型公开了一种高速纺丝交络一步法生产聚酰胺6POY/FDY复合纤维的设备,它的冷却装置为将徐冷装置安装在喷丝板的下方,环吹风冷却装置安装在徐冷装置的加热器下方,使从喷丝板挤出的熔体经过冷却装置,达到降低熔体细流冷却速率的效果,丝束冷却均匀一致;喷油装置安装在环吹风冷却装置的下方;拉伸热定型装置与导丝卷绕装置平行设置,拉伸热定型装置用于制备聚酰胺6POY全拉伸丝,导丝卷绕装置用于制备聚酰胺6FDY全拉伸丝;卷绕机构以4000m/min~5000m/min的速度将聚酰胺6POY与FDY的复合。该设备具有生产流程短、工序简单、制备生产成本低、能耗低、功效高,产品结构多元化及品质好的特点。
