Abstract

The invention discloses a fabric for a safety air bag. The quality fracture toughness of the fabric in the warp direction and/or the weft direction is 35-100 J/g. The sewed part of the fabric has excellent anti-slipping performance, good rigidity and softness and good foldability.

Description

technical field [0001] The invention relates to a fabric for an airbag. 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: after a collision, a gas-filled bag is quickly opened between the occupant and the interior components, allowing the occupant to pounce on the airbag, absorbing the kinetic energy of the passenger through the airbag's discharge throttling damping, so that the violent car The inner collision is cushioned to achieve the purpose of protecting passengers. [0003] The development of airbags has gon...
