Problems solved by technology

The hazards caused by static electricity limit the application fields of polyester fibers
At present, the common method is to add antistatic agent in the process of fiber preparation. Although a long-lasting antistatic effect can be obtained, due to the large amount of use, the preparation cost is high, and at the same time, due to the change of the overall process of fiber preparation, it is not conducive to production and promotion.

Abstract

The invention discloses an antistatic micron filament composite superfine fiber. The antistatic micron filament composite superfine fiber is prepared from the following components in parts by weight: 40-50 parts of polyester macromolecules, 30-40 parts of polyamide macromolecules, 4-8 parts of silver oxide nano powder materials, 1-5 parts of an antioxidant 1010 and 3-8 parts of a stabilizer, and the antistatic micron filament composite superfine fiber is characterized in that the powder particle size of the silver oxide nano powder materials is D less than 0.1 [mu] m; the polyester macromolecules is one of polyethylene glycol terephthalate or polybutylene terephthalate; the stabilizer is one or more of triphenyl phosphite, trimethyl phosphite and tridecyl phosphite. The antistatic micron filament composite fiber obtained through a preparation method has excellent antistatic capability, so that resistivity of the fiber surface can be effectively reduced; the antistatic property is efficient and lasting, so that static electricity can be eliminated in an extremely short time; the antistatic micron filament composite superfine fiber has wide environmental adaptability to prevention of generation and harm of the static electricity.

Description

technical field [0001] The invention relates to the technical field of chemical fibers, in particular to an antistatic micro-filament composite superfine fiber and a preparation method thereof. Background technique [0002] Due to the extremely fineness of ultra-fine fibers, the stiffness of the silk is greatly reduced, and the fabric feels extremely soft. The fine fibers can also increase the layered structure of the silk, increase the specific surface area and capillary effect, and make the internal reflection of the fiber more delicate on the surface. , so that it has a silky elegant luster, and has good moisture absorption and moisture dissipation. Microfiber has a wide range of uses: the fabric made of it, after advanced finishing such as sand washing and sanding, the surface forms a layer of appearance similar to peach skin, and it is extremely bulky, soft and smooth. [0003] There are many hazards of static electricity. The first hazard comes from the interaction of...
