Abstract
The present invention relates to a coated fabric for airbags for use in automobiles, and provides a coated fabric that has eliminated or reduced coating agent dots, which are not solved in traditional techniques, and that has a smaller difference in physical properties in tear strength in the width direction of the fabric. The coated fabric for airbags that exhibit excellent fabric properties and appearance such that there is little variation in physical properties in the width direction of the fabric, and such that there are fewer coating agent dots can be provided by a production method characterized by the use of a knife-on-air technique as a resin coating method, the use of a knife whose front and rear part are differently shaped, and the running angle of the fabric when the knife is pressed on the fabric being 3 to 15′.
