Airbags protect the body by applying a restraining force to the body that is smaller than the force the body would experience if it hit the dashboard or steering wheel suddenly, by spreading this force over a larger area. In this paper after laying out how an airbag works, the chemistry behind the airbags, mainly NaN3, KNO3 and SiO2 are described. It is shown how to estimate the amount of N2 gas and how to estimate the pressure required. Deflation of the airbag is outlined. Nylon and polyester fibres are widely used of airbag fabric. Nylon 6.6 is the most sought after fibre, polyesters are also used but to a lesser extent compared to nylon because of its advantages over polyester. The basic requirements of the fibres for airbags are: high strength, high stability, good ageing characteristics, coating, adhesion and functionality at extreme hot and cold conditions, tear strength, toughness and fog resistance, softness for reduced skin abrasion. The weaves used for the manufacturing of airbag fabric are plain weave and rip stop weave. Basically two types of fabrics are used, coated for the driver seats and uncoated for the co-driver seats and sides. Basic requirements of airbag fabric are: low fabric thickness, high strength in warp and weft direction, high propagation tear resistance, high anti-slip properties of the seams, resistance to ageing, defined dimensional stability, defined air permeability, product liability guaranteed for 15 years. Nowadays silicone coating has been predominant due to the following advantages: extended service life, adaptation to rough duty vehicles, reduced module size, improved recyclability, reduced cost. Different cutting methods are used for the two main types of materials: coated nylon can be cut with the traditional mechanical tools, uncoated nylon must be cut with a hot tool, such as laser to prevent fraying. Demands on the textile finishing result from the extremely high life time under the sketched environment. In order to achieve defined air permeability after the drying a calendar process follows.
