Example Embodiment

[0016] Example 1

[0017] This embodiment provides the equipment for producing polyamide 6POY / FDY composite fiber by one-step method of high-speed spinning and entangling. The spinning box is mainly composed of a metering pump, spinning components, a spinneret, and a box shell. Its main function is The polyamide melt is extruded through the metering pump, spinning assembly and spinneret in the spinning box to form a thin stream of melt, which plays a role of uniform temperature and heat preservation. See figure 1 , It is the structure diagram of the equipment for producing polyamide 6POY / FDY composite fiber by the interlacing one-step method. The main devices include spinneret 1, cooling device 2, ring blowing cooling device 3, fuel injection device 5, first stretching roller Group 9, the second stretching heat roller group 10, the first godet 8, the tension adjuster 11, the second godet 12, the third godet 13, the doubling device 14, the entanglement nozzle 15 and the winding ...

Abstract

The invention discloses a device for producing polyamide 6POY/FDY composite fiber according to a high-speed spinning and confounding one-step method. A cooling device of the device is a gradually-cooling device which is arranged below a spinneret plate. A cross air blow cooling device is arranged below a heater of the gradually-cooling device, the effect of lowering the cooling speed of melt thin flow can be achieved by enabling melt extruded out of the spinneret plate to pass through the cooling device, and yarn bundle cooling is uniform and consistent. An oil spraying device is arranged below the cross air blow cooling device. A stretching heat setting device and a yarn guiding and winding device are arranged in parallel. The stretching heat setting device is used for preparing polyamide 6POY fully-drawn yarn. The yarn guiding and winding device is used for preparing polyamide 6FDY fully-drawn yarn. A winding device is used for compositing 6POY with FDY at the speed ranging from 4000m/min to 5000m/min. The device has the advantages of being short in production process, simple in procedure, low in device production cost, low in energy consumption, high in efficacy, diversified in product structure and good in quality.

Description

technical field [0001] The invention relates to a spinning device, in particular to a device for producing polyamide 6POY / FDY composite fiber by high-speed spinning and intertwining in one step. Background technique [0002] At present, the technical approach for producing polyamide 6 POY / FDY composite fibers in the domestic and foreign markets is generally prepared by two-step production equipment or the technical route of entangled yarn network composite process processed by special compressed air nozzles (networkers). The production equipment is generally composed of polyamide 6FDY and POY fiber spinning forming equipment and POY and FDY or DY composite processing equipment, usually consisting of spinning screw, spinning box, metering pump, spinning assembly, spinneret, It is composed of oiling system, tunnel, network device and winding device, etc. The processing process is mainly made by high-speed spinning and spinning and stretching one-step method or conventional spi...
