Abstract:
A perforated non-woven fabric having at least one fiber layer that has a plurality of through holes. The total area of the through holes accounts for 10˜80% of the total area of the perforated non-woven fabric; the opening of the through holes is flat with the surface of the perforated non-woven fabric; and the density of through holes on the perforated non-woven fabric is 3/cm2˜100/cm2. The fiber density at the edge of each through hole is similar to or the same as the fiber density in other areas of the perforated non-woven fabric. The fiber surrounds the through hole, and only the surface of the fiber is bonded to each other.
