WIPO Patent Application WO/2023/146365
Kind Code:
A1
Abstract:
Disclosed are a method for preparing a polymer blend nanofiber washable with hot water and having resistance to solubility in water, and a polymer blend nanofiber washable with hot water and having resistance to solubility in water prepared thereby. The method for preparing a polymer blend nanofiber washable with hot water and having resistance to solubility in water comprises: a first step of obtaining a first fiber structure by spinning a mixed solution containing a solvent and a vinyl ester-based copolymer and an acrylic polymer dissolved in the solvent; and a second step of exposing the vinyl ester-based copolymer included in the obtained first fiber structure to a saponification solution containing at least one of distilled water, acid, or a base. The polymer blend nanofiber washable with hot water and having resistance to solubility in water can be prepared in the same way as above.
