Title:

METHOD FOR PREPARING CELLULOSE-POLYVINYL ALCOHOL FABRIC WITH IMPROVED SURFACE CHARACTERISTICS, CELLULOSE-POLYVINYL ALCOHOL FABRIC WITH IMPROVED SURFACE CHARACTERISTICS PREPARED THEREBY, AND FABRIC FOR WOUND HEALING COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2023/146369

Kind Code:

A1

Abstract:

Disposed are a method for preparing cellulose-polyvinyl alcohol fabric with improved surface characteristics, cellulose-polyvinyl alcohol fabric with improved surface characteristics prepared thereby, and fabric for wound healing comprising same. The method for preparing cellulose-polyvinyl alcohol fabric with improved surface characteristics comprises, after preparing a composite including a cellulose-based polymer and a polyvinyl alcohol-based polymer, exposing the composite to an alkali solution. The cellulose-polyvinyl alcohol fabric with improved surface characteristics is prepared by the method for preparing cellulose-polyvinyl alcohol fabric with improved surface characteristics. The fabric for wound healing includes the cellulose-polyvinyl alcohol fabric with improved surface characteristics.
