US 9,878,684 B2 · Coated fabric and method for producing same

Abstract

The present invention addresses the problem of providing a cloth which, when used as an air bag main body cloth, does not undergo the damage caused by a high-temperature gas generated from an inflater, and therefore has high heat resistance and is suitable for an air bag. The means for solving the problem is a coated cloth for an air bag, which is produced by applying an elastomer resin layer on at least one surface of a three-dimensional woven fabric in an amount of 50 to 500 g/m2 per one surface, said coated cloth being characterized by having void spaces formed therein, wherein the void content in the coated cloth is 15 to 60%. Preferably, the coated cloth is used in applications in which the coated cloth is attached onto the periphery of an inflater connection opening in an air bag.

Dependent claims

A coated fabric comprising a three dimensional construction woven fabric which is selected from a three-layer woven fabric and a four-layer woven fabric, wherein:

at least one surface of the three dimensional construction woven fabric is coated with an elastomer resin layer,
the elastomer resin layer is coated in an amount of 50 to 500 g/m2 per one surface;
and
the coated fabric has voids therein and has a void content of 15 to 60%, calculated as:
Void content (%)=(Apparent mass−Actual mass)/(Actual mass)×100;
and
Apparent mass(g)=(Thickness of uncoated base fabric(cm))×(Area of test piece(cm2))×(Density of original yarn(g/cm3))+((Thickness of coated base fabric(cm))−(Thickness of uncoated base fabric(cm)))×(Area of test piece(cm2))×(Density of resin(g/cm3)).
