Abstract
The invention discloses a far infrared polypropylene-polyamide composite superfine fiber and a production method of the far infrared polypropylene-polyamide composite superfine fiber. The far infrared polypropylene-polyamide composite superfine fiber is formed by taking superfine polypropylene fiber as a core yarn and externally coating a modified nylon 6 fiber layer; far infrared nano-powder material is filled in the externally coated and modified nylon 6 fiber layer; the modified nylon 6 is prepared by adding silicon dioxide nano-powder material into cerium oxide nano-powder material under active catalysis. The infrared emissivity of the acquired far infrared polypropylene-polyamide composite superfine fiber reaches more than 90% in a normal-temperature wavelength range of 2-16. Due to the modified nylon 6, the tensile strength of the nylon 6 is improved and the heat conductivity coefficient is lowered, so that the drawing property of the nylon 6 is better; and the nylon 6 can be coated and drawn with the superfine polypropylene fiber, so that the acquired textile fabric has the advantage of good thermal insulation property.
