Abstract

A method for producing a flocculent three dimensional fibrous bioactive material using an electrospinning process includes electrospinning a biodegradable fiber by applying an electrical charge to a nozzle of an electrospinning apparatus such that a spinning solution contained therein is made into an electrospun fiber, which is attracted toward a collector container that is electrically grounded and is filled with an ethanol liquid; receiving the electrospun fiber emitted from the nozzle on a surface of the ethanol liquid in the collector container; recovering and drying the electrospun fiber to obtain the flocculent three dimensional fibrous bioactive material having a bulk density of from about 0.01 g/cmto about 0.1 g/cmas measured in accordance with JIS L 1097.
