Embodiment 1

[0040] Dry the nylon 6 slices until the water content is below 300ppm, feed the masterbatch containing 20% ​​cubic boron nitride inorganic particles into the small silo, set the masterbatch addition amount to 2.5wt%, and enter the screw extrusion after being mixed by the mixer The inlet of the machine is melted in the screw extruder, and the discharge volume is controlled by the metering pump. The primary fiber is spun through the spinning assembly under the temperature control of the spinning box, cooled and solidified under the side blowing, and then passed through the oil nozzle. Oil the fibers evenly to bundle them and reduce friction. The fibers that have been oiled and bundled pass through the spinning shaft, enter the first roller (1GR), and then enter the coiler after being wound around the second roller (2GR) to obtain pre-oriented yarn POY.

[0043] Dry the nylon 6 slices until the water content is below 300ppm, feed the masterbatch containing 20% ​​hexagonal boron nitride inorganic particles into the small silo, set the masterbatch addition to 25wt%, and enter the screw extruder after being mixed by the mixer Imported, melted in the screw extruder, the discharge volume is controlled by the metering pump, the primary fiber is spun through the spinning assembly under the temperature control of the spinning box, cooled and solidified under the side blowing, and then passed through the oil nozzle The fibers are evenly oiled to bundle the fibers and reduce friction. The fibers that have been oiled and bundled pass through the spinning shaft, enter the first roller (1GR), and then enter the coiler after being wound around the second roller (2GR) to obtain pre-oriented yarn POY.

Embodiment 3

[0046] Dry the nylon 6 slices until the water content is less than 300ppm, feed the masterbatch containing 20% ​​hexagonal boron nitride inorganic particles into the small silo, set the masterbatch addition to 2.5wt%, and enter the screw extrusion after being mixed by the mixer The inlet of the screw extruder is melted in the screw extruder, and the discharge volume is controlled by the metering pump. The primary fiber is spun through the spinning assembly under the temperature control of the spinning box, cooled and solidified under the condition of side blowing, and then fed The oil nozzle evenly oils the fibers to bundle the fibers and reduce friction. The fibers that have been oiled and bundled pass through the spinning shaft, are entangled by the pre-interlacer, enter the first hot roll 1HR, and are wound on the first hot roll for 6~7 laps, and then pass through the second hot roll 2HR. Wrap 6~7 laps on it, and the stretched fiber between the first hot roller and the seco...

Abstract

The invention discloses polyamide fiber. The polyamide fiber at least comprises a polyamide type polymer, and boron nitride inorganic particles having an average particle size of 0.1-1 [mu]m. The weight of the boron nitride inorganic particles is 0.5-5 wt% of the total weight of the polyamide fiber. The polyamide fiber has cold sense and maintains good strength and elongation.

Description

technical field [0001] The invention relates to a polyamide fiber containing boron nitride inorganic particles. Background technique [0002] With the gradual warming of the earth's climate, functional fabrics have gradually attracted people's attention. Especially in hot and humid summer, people wish to wear some cool moisture-absorbing and quick-drying clothes to meet the requirement of lowering body temperature. In recent years, research has been conducted on contact cooling fabrics that can induce a cool feeling when worn and impart a cool feeling as fabrics for summer. In order to make such contact cold feeling type fibers, the method of improving the water absorption of fibers or improving the heat conductivity of fibers, etc. can be utilized, or the polymers that introduce hydrophilic groups such as hydroxyl groups or carboxyl groups can be utilized to make fibers, It is also possible to make fibers from a polymer mixed with a filler having high heat conductivit...
