  • Patent number: 8541321
    Abstract: A copolymerized polyether polyamide resin for coating on or for impregnation to a woven or knitted fabric, wherein elongation and elastic modulus of the copolymerized polyether polyamide resin are not less than 1000% and not more than 15 MPa, respectively. The copolymerized polyether polyamide resin has a constitution wherein said copolymerized polyether polyamide resin is such that a soft segment comprising a polyether polyamide constituted from a polyether diamine compound and a dicarboxylic acid compound is bonded to a hard segment comprising a polyamide constituted from an aminocarboxylic acid compound and/or a lactam compound.

  • Patent number: 7994076
    Abstract: A fabric for an airbag includes a synthetic fiber woven fabric in which at least one side thereof is coated with a synthetic resin. A range of 0.1 to 10 g/m2 of the synthetic resin is adhered to the synthetic fiber woven fabric having a cover factor of less than 2000 and a FR value of 55% or more. Air permeability of the fabric under a pressure difference of 100 kPa after adhesion is 0.01 to 1.00 L/cm2/min. The synthetic resin can be a polyamide-based resin having a soft segment comprising a polyol with a number average molecular weight of 100 to 5000.

  • Patent number: 7985702
    Abstract: A woven fabric for an airbag includes a synthetic fiber woven fabric having a cover factor of 2000 to 2500 in which at least one side thereof is coated with a synthetic resin. Air permeability of the woven fabric under a pressure difference of 100 kPa is 0.01 to 1.00 L/cm2/min. A resin film is present at an upper part of a single yarn at a thickness of 2 ?m or less on a central cross section of a weaving yarn part. A resin film is present at an upper part of a single yarn at a thickness of 2 to 30 ?m on a cross section at a border between weaving yarn parts. The synthetic resin can be a polyamide-based resin that includes a polyether compound of a number average molecular weight of 100 to 5000 as a soft segment.
