Abstract

The embodiments relate to a biodegradable polyester resin composition, to a nonwoven fabric, to a film, and to processes for preparing the same in which the biodegradable polyester resin composition comprises a specific diol component and a specific dicarboxylic acid component and may further comprise nanocellulose, whereby the biodegradability, flexibility, strength, and processability are enhanced. Since the biodegradable polyester resin composition has enhanced biodegradability, flexibility, strength, and processability as compared with the conventional natural biodegradable polymer widely used, it can be applied to various fields such as films, packaging materials, and nonwoven fabrics to show excellent characteristics.
