Title: Method for coating profecting and rigidifying a fabric made of heat-resistant fibers

Abstract: One may obtain an excellent protective coating for a fabric made of heat-resistant fibers, in particular a fabric made of glass fibers like those used for the manufacture of filters in the metallurgical industry, when use is made, as a starting material, of a composition comprising an organic part made of sugar and a mineral part comprising colloidal silica and wollastonite. This composition allows thermoforming of the fabric and gives to the same a very strong protection and a rigidity. This is particularly interesting when the fabric is used for making a filter like those used during the casting of a liquid metal, especially liquid aluminum.
