Abstract

The invention discloses a non-woven material composed of composite fibers with a core-spun yarn structure and a preparation method thereof, belonging to the technical field of fiber textile materials. The non-woven material is a non-woven micron fiber, a polydopamine / polyethyleneimine layer coated on the surface of the non-woven micron fiber from inside to outside, and a metal organic framework nanometer for connecting the polydopamine / polyethyleneimine layer. Composite fibers composed of fibers with a core-spun yarn structure are randomly piled up and wound in three-dimensional space; among them, the non-woven micron fiber is the core layer of the core-spun yarn structure, and the metal-organic framework nanofiber is the core-spun yarn-like structure. Structure of the cortex. The nonwoven material has porosity and good flexibility, and has broad application prospects in filtration, adsorption, catalysis and separation.
