Abstract

There is provided a high density woven fabric wherein air permeability under 50 kPa differential pressure is 2.5 L/cm2/min. or less, and air permeability index (50 kPa) calculated by the formula 1 is 1.2 or more.Air permeability index (50 kPa)=(Log (Q (55 kPa))−Log (Q (45 kPa)))/(Log 55−Log 45)  (Formula 1)Air permeability under Q(55 kPa):55 kPa differential pressure is (1/cm2/min.); andAir permeability under Q(45 kPa):45 kPa differential pressure is (1/cm2/min.).
