Problems solved by technology

[0002] At present, the composite ultra-fine fiber of polypropylene and nylon is made of simple twisting of ultra-fine polypropylene fiber and ultra-fine nylon fiber. This simple twisted composite fiber brings certain difficulties to the post-processing due to the different fiber properties. Difficulty, such as uniform dyeing problems, antistatic treatment, etc., but if coating compound is used, then in the production of functional acrylic composite ultrafine fibers, the drawing performance of these fiber materials will be changed due to the addition of functional materials , which brings some difficulty to the realization of cladding and compounding

Abstract

The invention discloses an antistatic polypropylene fiber and nylon composite superfine fiber and a production method thereof. The antistatic polypropylene fiber and nylon composite superfine fiber is composed of a superfine polypropylene fiber as a core wire and a modified nylon 6 fiber layer coating outside the core wire, and an antistatic nanopowder material is arranged in the externally coated modified nylon 6 fiber layer; and the modified nylon 6 is denatured nylon 6 obtained through adding a silica nanopowder material under the active catalysis of a cerium oxide nanopowder material. The result of experimental tests on the antistatic polypropylene fiber and nylon composite superfine fiber obtained through the production method shows that the surface resistivity of the antistatic polypropylene fiber and nylon composite superfine fiber is in a range of 10<7>-10<9>, and the provided denatured nylon 6 increases the tensile strength of nylon 6, so the stringiness of nylon 6 is good, thereby the coating wire drawing of nylon 6 and the superfine polypropylene fiber is realized, and textile fibers obtained through the coating wire drawing have the characteristic advantages of the polypropylene fiber, has the characteristic advantages of nylon and also has a good antistatic effect.
