Embodiment 1

[0020] In the present embodiment, the raw material composition and production method steps of mica nylon 6 FDY functional fiber are as follows:

[0021] 1. Raw material and weight percentage:

[0022] 1300°C Nano mica 5% and nylon 6 slices 95%.

[0023] Two, the production method of mica nylon 6 FDY functional fiber, comprises the following steps:

[0024] 1. Drying: Dry nylon 6 slices and 1300°C nano-mica;

[0025] 2. Preparation of spinning fluid: According to a certain ratio, use the masterbatch pump to accurately add 1300°C nano-mica, mix and melt with nylon 6 slices;

[0026] 3. Spinning: The above-mentioned spinning fluid is quantitatively pressed into the spinning assembly through the metering pump, and is sprayed out from the spinneret.

[0027] A tow is formed in the wire window. During the production process, keep stable temperature, humidity, melt pressure, spinning tension. The temperature in the spinning process is 262°C-264°C;

[0028] 4. Post-processin...

Abstract

The invention provides a mica-polyamide fiber 6 fully-drawn yarn (FDY) functional fiber, which comprises the following two components in percentage by weight: 5 percent of nano mica of 1,300 DEG C and 95 percent of polyamide fiber 6 slices. The invention also provides a production method for the mica-polyamide fiber 6 FDY functional fiber. Compared with the conventional polyamide fiber fabric, a fabric woven by using the mica-polyamide fiber 6 FDY functional fiber has the advantages of antistatic function, excellent heat conduction and water absorption effects of mica fibers and deodorizing effect of the mica fibers by adding the mica component based on the original advantages of the polyamide fiber fabric.

Description

technical field [0001] The invention relates to a mica nylon 6 FDY functional fiber and a production method thereof, belonging to the technical field of chemical fiber production. Background technique [0002] Mica is a layered silicate structure. Special physical and chemical properties, chemical stability, anti-ultraviolet, high temperature resistance, strong hydration, pearly luster, high refraction brightness. The physical properties and working principle of mica fiber: thin layer mica itself is completely transparent and colorless, its melting point is as high as 1300 degrees, and its properties will not change at all under high temperature of 550 degrees. Since the thermal conductivity of PET is only 0.03, the thermal conductivity of flaky mica is more than 5 times that of PET. In addition, the surface of nano-mica is charged, so the hydration is quite high, that is, the water content is extremely high, and the water needs to be removed above 500 degrees. In this way...
