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.

The present disclosure provides composite materials comprising reticular structures, such as nettings, mattings, grids, meshes or the like, ultrasonically bonded to outer layers of non-woven fibers. A composite material comprises a first layer of netting comprising strands and a second layer of nonwoven fibers in contact with the first layer. The nonwoven fibers are ultrasonically bonded to the strands of the netting at a plurality of attachment points. The basis weight of the netting and/or the fibers in the second layer are selected to optimize the bonding and increase the overall strength of the material. In embodiments wherein the composite material is used as a filter media, the filter has a longer lifespan, without compromising other performance factors, such as efficiency and capacity.
