Embodiment 1

[0069] Dry the nylon 6 slices until the water content is below 300ppm, feed the inorganic particle masterbatch containing silicon dioxide, aluminum oxide, and potassium oxide into the inlet of the screw extruder, and the slices enter the screw extruder through the silo at a temperature of 255°C Melting, the discharge volume is controlled by the metering pump, and the as-spun fibers are spun through the spinning assembly controlled by the spinning box at a temperature of 255°C, cooled and solidified under the condition of a side blowing wind speed of 25m / min, and then passed through the oil nozzle The fibers are evenly oiled to bundle the fibers and reduce friction, and the oiling 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 1500m / min, and then enter the coiler for coiling after passing through the second roller (2GR) at a winding speed of 1500m / min. For pre-oriented POY yarns with an or...

Embodiment 2

[0072] Dry the nylon 6 slices until the water content is below 300ppm. The polyvinylpyrrolidone masterbatch and the inorganic particle masterbatch containing silica, aluminum oxide and potassium oxide are fed into the inlet of the screw extruder, and the slices enter the screw extruder through the silo. Melting at 255°C, the discharge volume is controlled by the metering pump, and the as-spun fibers are spun through the spinning assembly whose temperature is controlled by the spinning box at 255°C, and cooled and solidified under the condition of side blowing wind speed 25m / min. , and then evenly oil the fibers 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 1500m / min, and then enter the coiler for coiling after passing through the second roller (2GR) at a winding speed of 1500m / min. For pre-oriented POY yarns ...

Embodiment 3

[0075] Carry out spinning with embodiment 2, carry out stretching false-twisting processing under the condition of elongation ratio 3.15 further, make false-twisted yarn DTY, test obtains elongation and reaches 30.5%, strength reaches 3.78dtex / cN, and moisture absorption rate difference is 6.0 %, the boiling yield is 7.5%, and the CR is 38.3%. In this embodiment, the average dispersed particle size of the inorganic particles contained in the fiber is 0.3 micron obtained by testing, and the content of polyvinylpyrrolidone in the fiber is 10wt%, the content of silicon element is 0.23wt%, the content of aluminum element is 0.21wt%, potassium The element content is 0.083wt%. The fiber false twisted yarn DTY100% is used to spin the fabric, and the temperature of the fabric surface is lowered by 1.5 degrees by using an infrared sensor temperature camera to shoot and test.

Abstract

The invention discloses a coldness sense polyamide fiber and its making method. The coldness sense polyamide fiber comprises a polyamide polymer and inorganic metal oxide particles with the average particle size of 0.1-1.0mum, and the inorganic metal oxide particles contain a silicon element, an aluminum element and a potassium element, and the amounts of the silicon element, the aluminum element and the potassium element account for 0.23-2.3wt%, 0.21-2.1wt% and 0.083-0.83wt% of the total weight of the fiber respectively. Preferably, the fiber contains 3.0-10.0wt% of polyvinylpyrrolidone. The fiber has the advantages of coldness sense, good strength and elongation, and excellent moisture absorption performance.

Description

technical field [0001] The invention relates to a cold-sensing polyamide fiber. 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 using such fibers, although it is true...
