METHOF OF MANUFACTURING POLY-VINYL-ALCOHOL NANO FIBER NON-WOVEN

摘要

The present invention relates to a method for producing a polyvinyl alcohol nanofiber nonwoven fabric, comprising: dissolving a polyvinyl alcohol resin in distilled water to form a spinning solution having a predetermined solid component; An electrospinning step of generating a polyvinyl alcohol nano web by spinning the spinning solution formed in the dissolving step through a nozzle on which a voltage of an electrospinning device is applied to accumulate on a collector; And;And heat-treating the polyvinyl alcohol nanoweb generated in the electrospinning step from a temperature above a glass transition temperature to a temperature below a crystallization temperature.;The method for producing a polyvinyl alcohol nanofiber nonwoven fabric according to the present invention can be easily developed by improving the crystallinity through heat treatment and the water resistance through partial crosslinking, using only distilled water as a solvent, and not performing any chemical treatment. By not expressing the properties of the nanoweb prepared during electrospinning without changing the inherent properties of the biocompatibility of polyvinyl alcohol has the advantage that it can have a broad expansion into medical applications.;Electrospinning, polyvinyl alcohol, PVA, biocompatible polymer
