Title:
AIRBAG BASE FABRIC AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2022/080432
Kind Code:
A1
Abstract:
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/m2 to 100 g/m2 (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.
