ABSTRACT:
The object of this invention is to provide a heat resistant fabric having high stiffness at high temperature and also high chemicals resistance.The heat resistant fabric of this invention is a fabric consisting of heat resistant fibers, characterized in that the contacts between the fibers constituting the fabric are bound by means of an inorganic binder. Furthermore, a preferable process for preparing the heat resistant fabric of this invention comprises the steps of impregnating a fabric consisting of heat resistant fibers with a sodium silicate aqueous solution, and drying in an atmosphere containing carbon dioxide, to bind the contacts between the fibers constituting the fabric by means of silicon oxide.
