Problems solved by technology

[0002] At present, polyester-acrylic composite superfine fibers are all simply twisted from superfine polypropylene fibers and superfine nylon fibers. This simple twisted composite fiber 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-acrylic composite superfine fibers, the addition of functional materials will change the drawing performance of these fiber materials, giving the coating The realization brings some difficulty

Abstract

The invention discloses a far-infrared polyester and polypropylene fiber composite superfine fiber and a production method thereof. The far-infrared polyester and polypropylene fiber composite superfine fiber is composed of a superfine polypropylene fiber as a core wire and a polyester PET fiber layer coating outside the core wire, and a far-infrared nanopowder material is arranged in the externally-coating polyester PET fiber layer. The far-infrared polyester and polypropylene fiber composite superfine fiber obtained through the production method has an infrared emissivity reaching above 90-92% at normal temperature in a wavelength range of 2-16, so the coating wire drawing of the polyester PET and the superfine polypropylene fiber is conveniently realized, and the heat accumulation capability of the composite fiber is improved, thereby textile fabrics obtained through using the composite fiber have a good warming performance.
