Embodiment 1
[0063] The polyethylene terephthalate chips with a moisture content of about 30ppm after vacuum drying are passed through the screw extruder. Press into the assembly.
[0064] 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 90dtex / 48F to obtain 4-leaf wind type fully oriented yarn FOY.
[0065] False-twisting 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 84dtex / 48F 4-blade type false twist processed yar...
Embodiment 2
[0067] The polyethylene terephthalate chips with a moisture content of about 30ppm after vacuum drying are passed through the screw extruder. Press into the assembly.
[0068] 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 90dtex / 48F to obtain 4-leaf wind type fully oriented yarn FOY.
[0069] False-twist 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 84dtex / 48F 4-blade type false twist processed yar...
Embodiment 3
[0071] The polyethylene terephthalate chips with a moisture content of about 30ppm after vacuum drying are passed through the screw extruder. Press into the assembly.
[0072] 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 90dtex / 48F to obtain 4-leaf wind type fully oriented yarn FOY.
[0073] False-twisting the wound stretched yarn FOY, using medium-high temperature false-twisting, the temperature of the first hot box of the false twister is set to 180°C, the temperature of the second hot box is room temperature, the ratio is 1.075, the processing speed is 500m / min, and the fineness is 84dtex / 48F 4-blade type false twist processed y...
