An aqueous inorganic or hybrid binder composition includes (as % by weight of the solid matter): from 55 to 100% of at least one alkali metal silicate exhibiting an Si/alkali metal weight ratio which varies from 0.3 to 2, from 0 to 35% of at least one plasticizing agent, and from 0 to 10% of one or more additives. Fibrous products can obtained from this composition, in particular based on mineral fibers, such as mats, screens, woven fabrics, in particular painter's canvases, and knitted fabrics.
