Technological watch

An implementation relates to: a biodegradable polyester resin composition comprising a specific diol component and a dicarboxylic acid component, additionally comprising a nanocellulose, and having improved biodegradability, flexibility, strength and processability; a nonwoven fabric and a film; and a manufacturing method therefor. The biodegradable polyester resin composition has biodegradability, flexibility, strength and processability that are superior to those of a conventionally and widely used natural biodegradable polymer, and thus can be applied in various fields such those of film, packaging material and nonwoven fabric and exhibit excellent characteristics.
