Manufacturing methods and ultra-fine fiber nonwoven fabric of ultra-fine fiber non-woven fabric

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an ultrafine fiber nonwoven fabric, which is capable of easily producing the ultrafine fiber nonwoven fabric having a three-dimensional thickness and fine pores capable of removing viruses, bacteria, or the like.;SOLUTION: A method for producing an ultrafine fiber nonwoven fabric by using an electrospinning device for ejecting a polymer solution from a nozzle toward a collector by utilizing an electric potential difference to spin ultrafine fibers, includes arranging a mesh sheet made of a fluorine-based resin on the collector during the electrospinning. The mesh sheet made of the fluorine-based resin is a woven fabric made of a fluorine-based resin fiber having 3D porosity of 90 to 99% or a knitted fabric made of a fluorine-based resin fiber having 3D porosity of 70 to 91%.;COPYRIGHT: (C)2013,JPO&INPIT
