Abstract:
A high density fabric for air bag obtained by shrink processing at a overfeed ratio of 0-15%, and having an air permeability under a differential pressure of 50 kPa of 2.5 L/cm2/min. or less, and an air permeability index (50 kPa) calculate by formula (1) of 1.2 or more:Air pemeability index (50 kPa) =(Log (Q(55kPa))âˆ’Log(Q(45kPa)))/(Log 55âˆ’Log 45)â€ƒâ€ƒ(Formula 1) Q(55kPa):air permeability under 55kPa differential pressure (l/cm2/min.) Q(45kPa):air permeability under 45kPa differential pressure (l/cm2/min.).
