Abstract: Disclosed in the present disclosure are a cut-resistant multifunctional melt-spun composite fiber, and a fabrication method and application thereof. Porous zeolite, a carbon nanotube and an ultra-high molecular weight polyethylene microfiber are taken as a composite functional substrate. A special crystal structure of the porous zeolite in a fiber allows the fiber to have a larger stress field and stronger adsorption performance on vapor molecules in an environment. The carbon nanotube has excellent electrical conductivity, endowing the fiber with an antistatic effect, and a tubular structure of the carbon nanotube effectively reduces material density, such that light weight of the fiber is achieved. Finally, the ultra-high molecular weight polyethylene microfiber selected by the present disclosure can improve fiber strength and performance stability, and further forms a synergistic effect together with the porous zeolite and the carbon nanotube, such that the obtained fiber product has diversified functions.
