  • Patent number: 6444596
    Abstract: A base cloth for an air bag is obtained by forming a film of a silicone modified thermoplastic polyurethane resin having a polysiloxane segment on a surface of a woven fabric, and the air bag is formed of the base cloth. Since an organic solvent is not used when the resin is prepared, its workability is superior, the resin is safe for the human body. Also, the air bag can be quickly developed in a wide range from an extremely low temperature to a high temperature, and there is no problem of adhesion or sticking. Thus, the air bag having a stable performance and the base cloth for the air bag are provided.
