Abstract
Abstract The flameproofed water-repellent sheet of the present invention has a construction that a sheet-form base material consisting of a woven or knitted fabric of organic fiber is impregnated with a silicone resin varnish containing at least a fibrous potassium titanate and said silicone resin varnish is dried and cured. Since it has excellent non-flamability and water-repellency and, in addition, a flexibility and a high sewing suitability and a high folding endurance, it can be utilized quite effectively as a tent fabric for large-sized tents, storehouse type tents and the like and as a wall material for pool, and the like.
