A non-woven fabric composed of nano fiber with biomimetic like structure and a process of preparing for the same

摘要

PURPOSE: A nano fiber non-woven fabric is characterized by having a structure like lotus leaves or taro leaves. A manufacturing method thereof is characterized by increasing vapor permeability, waterproof and filtering property. The fabric is useful for fabric having vapor permeability and waterproof, artificial leather and a high efficiency filter. CONSTITUTION: The nano fiber non-woven fabric contains thermoplastic beads having under 10m of diameter on spot type. The non-woven fabric is obtained by the steps of: electric-spinning a polyester spinning solution through nozzles(3) on a collector(4) to manufacture polyester nano fiber non-woven fabric having 500nm or less of diameter; preparing polyurethane or polymethyl methacrylate nano fiber non-woven fabric formed with the beads; and then laminating the polyurethane or polymethyl methacrylate nano fiber non-woven fabric on the polyester nano fiber non-woven fabric.
