Problems solved by technology

[0002] Airbag fabric is an important raw material for automobile safety components. The performance requirements of the airbag fabric are high, and the airbag fabric must have precise air permeability, because it is necessary to ensure that the airbag is inflated and deployed without breaking. Affect the forming effect of the airbag, thereby affecting the protective effect of the airbag; if the air permeability is too low, the gas in it will not be released in time, resulting in excessive impact on the body of the driver and passenger. At the same time, it must have high strength, good elongation performance, High elasticity and resilience, need to withstand the instantaneous impact from high temperature and high velocity gas
The common airbag cloth currently available on the market is coated with a coating agent on its surface to prevent the gas from leaking from the gaps in the fabric to the outside, so as to maintain the internal pressure. The use of coating agent does not affect the impact resistance of the airbag cloth. Improved performance
