Abstract

A fabric for an airbag, characterized in that: the fabric for an airbag is composed of a ground structure and side structures located on both sides of the ground structure, and the ground structure and the side structures use two kinds of filaments with different initial moduli, And the difference rate of the initial modulus of the high initial modulus filament for the ground structure and the initial modulus of the low initial modulus filament for the edge structure is 15.0-40.0%, and the skewness of the fabric is ≤ 2.0 %. The airbag fabric of the invention has small skewness, good tensile fracture and tear performance, good dimensional stability and low cost.

Description

technical field [0001] The present invention relates to a fabric for an airbag with a small skewness. Background technique [0002] In recent years, with the rapid development of the automobile industry and the development and construction of expressways, the speed of automobiles has become faster and faster, and traffic accidents have occurred more frequently, so the safety of automobiles has become particularly important. As one of the safety spare parts of automobiles, the installation rate of airbags increases rapidly with the improvement of people's safety awareness. The basic working process of the airbag is: after a collision, quickly open a bag filled with gas between the occupant and the interior components, let the occupant pounce on the airbag, and absorb the kinetic energy of the passenger through the discharge throttling damping of the airbag, making the violent crash Collisions inside the car are buffered to protect passengers. [0003] At present, water-jet ...
