Examples
Embodiment 1
[0031] Place the polyester FDY fiber with a circular cross-section of 73dtex / 192f in the downstream direction of the airflow 5cm away from the plasma discharge area, and pump the plasma to a vacuum of 1×10 -2 Pa, with oxygen as the carrier gas, sulfur dioxide as the modified gas, and oxygen / sulfur dioxide as a mixed gas into the plasma, the volume content of sulfur dioxide is 10%, the gas pressure is 5Pa, and the discharge power is 100W. After 5s discharge treatment, it is obtained Sulfonic acid modified fiber.
Embodiment 2
[0033] Place the polyester FDY fiber with a circular cross-section of 73dtex / 192f in the downstream direction of the airflow 60cm away from the plasma discharge area, and pump the plasma to a vacuum of 5×10 -2 Pa, with oxygen as the carrier gas, sulfur dioxide as the modified gas, and oxygen / sulfur dioxide as a mixed gas into the plasma, the volume content of sulfur dioxide is 90%, the gas pressure is 100Pa, and the discharge power is 100W. After 120s discharge treatment, it is obtained Sulfonic acid modified fiber.
Embodiment 3
[0035] Place the polyester FDY fiber with a circular cross-section of 73dtex / 192f in the downstream direction of the airflow 10cm away from the plasma discharge area, and pump the plasma to a vacuum of 1×10 -2 Pa, with oxygen as the carrier gas, sulfur dioxide as the modified gas, and oxygen / sulfur dioxide as a mixed gas into the plasma, the volume content of sulfur dioxide is 50%, the gas pressure is 30Pa, and the discharge power is 20W. After 30s discharge treatment, it is obtained Sulfonic acid modified fiber.
