Embodiment 1

[0041] Dry the bright polyester chips until the water content is below 100ppm, feed the masterbatch containing 20% ​​cubic boron nitride inorganic particles into the small silo, set the amount of the masterbatch to 2.5wt%, and enter the The inlet of the screw extruder, the screw extruder melts at 285°C, the discharge volume is controlled by the metering pump, and the primary fiber is spun through the spinning assembly whose temperature is controlled by the spinning box at 285°C. Cool and solidify under the condition of blowing wind speed 25m / min, and then oil the fibers evenly through the oil nozzle to bundle the fibers and reduce friction. The oil supply rate is 0.9%. The fibers that have been oiled and bundled pass through the spinning shaft and enter the first roller (1GR) at a speed of 2500m / min, and then enter the coiler for coiling after passing through the second roller (2GR) at a winding speed of 2500m / min. Pre-oriented yarn POY, the coiling speed of the coiler is 2450...

Embodiment 2

[0044]Dry the bright polyester chips to a moisture content of less than 100ppm, feed the masterbatch containing 20% ​​hexagonal boron nitride inorganic particles into the small silo, set the masterbatch addition to 25wt%, and enter the screw after being mixed by the mixer The inlet of the extruder, the screw extruder melts at a temperature of 285°C, the discharge volume is controlled by a metering pump, and the primary fibers are spun through the spinning assembly whose temperature is controlled at 285°C by the spinning box, and blown on the side Cool and solidify under the condition of wind speed of 25m / min, and then oil the fibers evenly through the oil nozzle to bundle the fibers and reduce friction. The oil supply rate is 0.9%. The fibers that have been oiled and bundled pass through the spinning shaft and enter the first roller (1GR) at a speed of 2500m / min, and then enter the coiler for coiling after passing through the second roller (2GR) at a winding speed of 2500m / min....

Embodiment 3

[0047] Dry the bright polyester chips until the water content is less than 100ppm, feed the masterbatch containing 20% ​​hexagonal boron nitride inorganic particles into the small silo, set the amount of the masterbatch to 2.5wt%, and enter the The inlet of the screw extruder, the screw extruder melts at 285°C, the discharge volume is controlled by the metering pump, and the primary fiber is spun through the spinning assembly whose temperature is controlled by the spinning box at 285°C. Cool and solidify under the condition of blowing wind speed 25m / min, and then oil the fibers evenly through the oil nozzle to bundle the fibers and reduce friction. The oil supply rate is 0.9%. The fibers that have been oiled and bundled pass through the spinning shaft, are entangled by the pre-interlacer, enter the first hot roller 1HR (temperature is 90°C), and are wound on the first hot roller for 6~7 laps, and then pass through the second hot roller. The second hot roller 2HR is also wound ...

Abstract

The invention discloses polyester fibers. The fibers at least contain a polyester polymer and boron nitride inorganic particles with an average particle size of 0.1-1.0 [mu]m. The boron nitride inorganic particles accounts for 0.5-5 wt% of a total weight of the fibers. The polyester fibers provided by the invention have a cold sense and keep good strength and elongation degree.

Description

technical field [0001] The invention relates to a polyester fiber containing boron nitride inorganic particles. Background technique [0002] With the gradual warming of the earth's climate, people have gradually paid attention to functional fabrics. Especially in hot and humid summer, people wish to wear some cool moisture-absorbing and quick-drying clothes to reduce the human body's requirement for ambient temperature. In recent years, as fabrics for summer, studies have been conducted on fabrics using fibers with excellent contact cool feeling that cause a cool feeling when worn and provide a cool feeling. The water absorption or the method of improving the heat conductivity of the fiber, etc., or the hydrophilic base resin fiber such as carboxyl group or carboxyl group can be introduced, or the fiber containing the resin mixed with the filler with high heat conductivity can be introduced or the surface can be treated. Plated fibers, etc. However, in the case of us...
