Airjet Textured Yarn Fabrics for Airbag: An Innovative Approach

Airbag act as safety device in vehicles, which activates when sensor detects crash or collision. Worldwide majority of airbag fabric is made of Nylon 66 yarn. The problem in airbag are repositioning of airbag, space occupied and cost. In this project attempt has been made to make airbag fabric from Nylon 66/Polyester combination airjet textured yarn to reduce the cost. Also attempt has been made to reduce fabric volume to reduce space occupied using air textured blend yarns. The 6 different type of airbag fabric has been manufactured and compared with commercially available fabric. The some of the parameters has been changed during process like Low tenacity (LT) Polyester has been replaced by High tenacity (HT) Polyester to get better properties of fabric. The fabric has been further coated to improve the air permeability and performance of the fabric. The further it has been observed that fabric properties can be match with commercial fabric. This airbag fabric can efficiently use for secondary airbags.
