汽车安全袋自七十年代初问世以来,如今已发展第四代产品了。第一代汽车用充气安全袋是以尼龙丝66织物涂覆氯丁烯来制造的,所用原料为420ｄｔｅｘ或者840ｄｔｅｘ的尼龙纤维,设计要求织物能抗炽热气体和微粒子散射。第二代充气袋仍为涂层织物,只是涂层原料发展为硅橡胶。第三代 Since the advent of automotive safety bags in the early 1970s, the fourth generation of products has now been developed. The first generation of automotive inflatable safety bags were made from nylon 66 fabric coated with neoprene, using 420dtex or 840dtex nylon fibers designed to resist the scattering of hot gases and particulates. The second generation of inflatable bags are still coated fabrics, but the coating material developed into silicone rubber. Third Generation
