The present invention relates to a coated fabric for an air bag obtained by applying an elastomer resin onto at least one side of a woven fabric made from synthetic fiber. The applied amount of the elastomer resin is 25 to 60 g/m.sup.2. The average resin thickness on warp and weft at head top of the woven fabric surface is 8 μm to 45 μm. The number of foams having diameter of 30 μm or larger is 100 or more/cm.sup.2 on the surface of a resin layer.

A method of making a flame resistant airbag suitable for use in aviation applications is discussed. A flame resistant fabric for the use in the construction of aviation airbags is woven from a high tenacity continuous polyester fiber substrate. A polyurethane coating is applied to the woven fabric, which has been treated with a flame retardant, to impart high pressure permeability resistance to the flame resistant fabric. The resulting fabric complies with Federal Aviation Requirement 25.853 as well as exhibits sufficient high pressure permeability resistance which is measured as a pressure of not less than about 198 kPa after five seconds from an initial inflation and pressurization to about 200 kPa, such as may be encountered in and during an inflation of aviation airbag assemblies.

A base fabric for an airbag is formed of a polyamide fiber, wherein a CV value of a weaving density for every 20 cm in a base fabric weft direction is equal to or less than 0.5%, and original-yarn strength usage rates in the warp direction and the weft direction are equal to or more than 85%.

An airbag textile containing a woven textile having an inner side and an outer side, a primer layer on the outer side of the textile and a gas barrier layer on the primer layer. The primer layer contains a first thermoplastic polymer and has a surface roughness and a plurality of holes extending at least partially through the thickness of the primer layer. The gas barrier layer contains a second thermoplastic polymer and at least partially fills in the surface roughness and holes of the primer layer.

Provided is an airbag base fabric that has a low air permeability sufficient to ensure the safety of occupants and heat resistance sufficient to withstand high-power, high-temperature gas generated from a recent downsized inflator, and that is capable of being packaged compactly. Also provided is an airbag comprising the base fabric. An airbag base fabric comprising a synthetic fiber multifilament having a total fineness of 500 to 750 dtex, the airbag base fabric having an areal weight of 225 to 245 g/m.sup.2, air permeability at 20 kPa of 0.2 to 0.8 L/cm.sup.2/min, and edgecomb resistance according to the ASTM D 6479 method of 300 to 600 N in both warp and weft directions.

A base fabric, having a coefficient of variation CV1 (100×standard deviation/average value) of 3.0% or less in a length direction of a weft-direction disintegrated yarn strength and a coefficient of variation CV2 (100×standard deviation/average value) of 4.0 or less in a length direction of a weft-direction disintegrated yarn elongation.

A safety airbag mesh, which includes a fiber layer. The fiber layer includes a warp fiber unit that extends warpwise and a weft fiber unit that extends weftwise, characterized in that the warp fiber unit includes a plurality of first fibers and second fibers arranged weftwise. The first fibers warpwise cover a buffer area and a support area, and the first fibers in the buffer area take on nonlinear formation, and extend longer than the second fibers in the area.

An air bag base cloth according to the present invention includes a base cloth main body formed of synthetic fibers, and a synthetic resin layer with which at least one face of the base cloth main body is coated, and the moisture content measured in accordance with JIS L 1096.8.10 is 0.5% or less.

Object:

Conventional woven fabrics mounted on a loom have a fabric length difference between the center portion and the sides of the woven fabric, which increases the flaring rate. In the scouring shrinkage step, yarns shrink and the crimp ratio is changed, which further increases flaring.

Means for achieving object:

The use of a bar temple with a ring function in the weaving process reduces protrusions. Further, by setting the boiling-water shrinkage rate of incorporated additional yarn lower than that of base yarn, the shrinkage of the sides of the fabric can be efficiently suppressed.

A heat resistant reinforcing cloth for an airbag is provided. The heat resistant reinforcing cloth can be disposed on an airbag part which contacts expansion gas in an airbag. The airbag can be deployed and expanded by expansion gas ejected from an inflator. The heat resistant reinforcing cloth comprises: a base fabric of natural fibers selected from the group consisting of cotton, hemp, flax, and combinations thereof; and a silicone rubber layer on both sides of the base fabric.
