Embodiment 1
[0078] The polyethylene terephthalate chips with a moisture content of about 30ppm after vacuum drying are passed through the screw extruder. Press into the assembly.
[0079] Swastika-type spinneret is used for spinning, the cooling distance is 65mm, cooled by side blowing, the wind temperature is 20°C, the wind speed is 20m / min, the set winding speed is 3200m / min, the temperature of the first hot roller is 90°C, and the second The temperature of the hot rolls was 145° C., and the elongation ratio between the two hot rolls was 1.36. The fineness is controlled to 80dtex / 48F, and the 4-leaf wind type fully oriented yarn FOY is obtained.
[0080] False-twist the wound stretched yarn FOY, using low-temperature false-twisting, setting the temperature of the first hot box of the false twister to 100°C, the temperature of the second hot box to room temperature, the ratio of 1.075, and the processing speed of 500m / min to obtain a denier of 72dtex / 48F 4-blade type false twist proce...
Embodiment 2
[0082] The polyethylene terephthalate chips with a moisture content of about 30ppm after vacuum drying are passed through the screw extruder. Press into the assembly.
[0083] Swastika-type spinneret is used for spinning, the cooling distance is 65mm, cooled by side blowing, the wind temperature is 20°C, the wind speed is 20m / min, the set winding speed is 3200m / min, the temperature of the first hot roller is 90°C, and the second The temperature of the hot rolls was 145° C., and the elongation ratio between the two hot rolls was 1.36. The fineness is controlled to 80dtex / 48F, and the 4-leaf wind type fully oriented yarn FOY is obtained.
[0084] False-twisting the wound stretched yarn FOY, using medium-temperature false-twisting, setting the temperature of the first hot box of the false twister to 140°C, the temperature of the second hot box to room temperature, the ratio of 1.075, and the processing speed of 500m / min to obtain a denier of 72dtex / 48F 4-leaf wind type false t...
Embodiment 3
[0086] The polyethylene terephthalate chips with a moisture content of about 30ppm after vacuum drying are passed through the screw extruder. Press into the assembly.
[0087] Swastika-type spinneret is used for spinning, the cooling distance is 65mm, cooled by side blowing, the wind temperature is 20°C, the wind speed is 20m / min, the set winding speed is 3200m / min, the temperature of the first hot roller is 90°C, and the second The temperature of the hot rolls was 145° C., and the elongation ratio between the two hot rolls was 1.36. The fineness is controlled to 80dtex / 48F, and the 4-leaf wind type fully oriented yarn FOY is obtained.
[0088] False-twisting the wound stretched yarn FOY, adopting medium-high temperature false-twisting, setting the temperature of the first hot box of the false twister to 180°C, the temperature of the second hot box to room temperature, the ratio of 1.075, and the processing speed of 500m / min to obtain a denier of 72dtex / 48F 4-leaf wind type...
