Spunbonded nonwoven fabric and filter using same

摘要

The purpose of the present invention is to obtain a spunbonded nonwoven fabric, which comprises a single-component polyester-based fibers, having a high basis weight and a high rigidity by embossing, which is difficult to attain in the conventional art. Further, the present invention provides a filter base material having excellent pleatability, pleat retention property and durability, and a filter using thereof. The present spunbonded nonwoven fabric is obtained by subjecting a deposited fiber assembly to a thermocompression bonding by embossing with a pair of an embossing roll and a flat metal roll, and has a basis weight of 150 to 400 g/m2, a longitudinal bending repulsion of 20 to 60 mN and a longitudinal tensile strength of 400 N/5 cm or more.
