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.
