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.

Abstract: The present disclosure relates to a method for producing a nonwoven fabric which improves the impregnation property of a fabric softener in the nonwoven fabric so as to apply the nonwoven fabric to a dryer sheet (sheet-type fabric softener). In a nonwoven fabric made of two types of polyester long fiber mixed filament yarns, by widening the specific surface area, adjusting the evenness deviation to be small and increasing the porosity, the impregnation property of a fabric softener is improved even when the nonwoven fabric is made lightweight, and the nonwoven fabric can be applied to a dryer sheet.

Abstract: The present disclosure relates to a method for preparing a non-woven fabric which improves impregnation and release properties of a fabric softener in the non-woven fabric in order to apply the non-woven fabric to a dryer sheet (sheet-type fabric softener). When increasing porosity and specific surface area in a non-woven fabric made of two-component blended polyester long fibers, impregnation and release rate of a fabric softener are improved even when the non-woven fabric is lightened, making it possible to apply the non-woven fabric to a dryer sheet.
