Problems solved by technology

[0002] At present, polyester and nylon composite superfine fibers are all made of superfine polyester fibers and superfine nylon fibers by simple twisting. This kind of simple twisted composite fibers brings certain difficulties to the post-processing due to the different fiber properties. Difficulty, such as uniform dyeing problems, etc., but if coating compounding is used, then in the production of functional polyester-nylon composite superfine fibers, the drawing performance of these fiber materials will be changed due to the addition of functional materials, and the coating The realization brings some difficulty

Abstract

The invention discloses a far infrared polyester and nylon composite superfine fiber and a production method thereof. The far infrared polyester and nylon composite superfine fiber is formed by externally coating a modified nylon 6 fiber layer by taking a superfine polyester fiber as a core thread, wherein a far infrared nano-powder material is arranged in the externally coated modified nylon 6 fiber layer; modified nylon 6 is modified by adding nylon 6 into a silica nano-powder material under active catalysis of a cerium oxide nano-powder material. According to the obtained far infrared polyester and nylon composite superfine fiber, the infrared emitting ability can be up to 90-92 percent within the normal temperature wavelength range of 2-16; according to the modified nylon 6, the tensile strength of the nylon 6 is improved, the heat conductivity coefficient is reduced, and the drawing performance of the nylon 6 is high, so that coating and the drawing between the nylon 6 and the superfine polyester fiber can be realized, and a piece of obtained textile fabric has good thermal insulation properties.
