Abstract

The present disclosure relates to a method for producing a nonwoven fabric that improves filtration performance when applied as a filter material. By adjusting the modification ratio of the Y-shaped cross-section of polyester filaments constituting the nonwoven fabric, when applied to a filter by increasing a specific surface area of the nonwoven fabric, it increases the collection amount of the materials to be filtered and maintains a low differential pressure, thus enabling long-term use.
