  • High density fabric for air bag and method for manufacturing high density fabric
    Patent number: 6832633
    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.); and Air permeability under Q(45 kPa):45 kPa differential pressure is (1/cm2/min.).

  • Process for preparing antistatic fiber
    Patent number: 4940560
    Abstract: An antistatic fiber obtained by melt spinning of a fiber-forming thermoplastic polymer containing at least one of polyoxyalkylene glycol and its derivatives in an amount of not less than 0.5% by weight, characterized in that said fiber has a half life time of electric charge leakage of not more than 150 seconds before and after treatment with a weight decreasing agent and, when treated with a weight decreasing agent, provides a number of streaks arranged in parallel in the lengthwise direction at the surface.
