Airbag Base Fabric and Method for Manufacturing Same - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240011202 titled 'Airbag Base Fabric and Method for Manufacturing Same
Simplified Explanation
The abstract describes an airbag base fabric that has reduced combustibility and meets the requirements of FMVSS 302 after environmental testing. The fabric is made of polyamide multifilament textile and has a silicone film on at least one surface. The silicone film weight ranges from 10 g/m to 100 g/m, and the cyclopentanone content ranges from 0-250 ppm in relation to the textile weight. The fabric has a shrinkage rate of 0-1.4% after heating for 60 minutes at 105°C, and a blade combing resistance of 350 N or greater after 400 hours in an environment of 85°C and 95% relative humidity.

Original Abstract Submitted
provided is an airbag base fabric in which combustibility due to both resin coating surface ignition and non-fabric surface ignition in the airbag base fabric is suppressed according to combustibility evaluation as defined in fmvss 302 after environmental testing. the present invention pertains to a polyamide multifilament textile airbag base fabric and a method for manufacturing the same, the airbag base fabric being characterized by having a silicone film on at least one surface of the textile, the silicone film weight being 10 g/mto 100 g/m(inclusive), the cyclopentanone content being 0-250 ppm (inclusive) in relation to the textile weight, the greater shrinkage rate among the shrinkage rates in each of the warp and weft directions before and after heating for 60 minutes at 105� c. being 0-1.4% (inclusive), and the blade combing resistance after 400 hours in an environment of 85� c. and 95% relative humidity being 350 n or greater.
