Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings.
[0017] As shown in Figure 2, ① use the large bright fiber grade polyester chip with an amount of 75% by weight as the first raw material A, enter the material continuous drying tower 1, and make the big bright fiber grade polyester with a moisture content < 35PPm Dry slices, enter the first screw extruder 3, and become spinnable polyester melt through melt extrusion. The melt extrusion process of the first screw extruder 3 is equipped with 3 to 5 heating zones. The heating of each zone The temperature is set between 275°C and 295°C (for example: 275°C, 285°C, 295°C), and then the polyester melt is transported to the spinning box 5 and further evenly distributed to the spinning box 5. Among the "rice" type polyester and nylon composite components, it is a component. In addition, in the actual production process, a pre-filter can be set between the first screw extruder ...
