ABSTRACT:
A method for producing fire retardant or non-combustible fibrous products. Fibrous organic or inorganic materials, or a mixture thereof, are processed into a slurry, which is then intimately mixed with a boron-containing mineral and a mineral acid. The mixture is allowed to ripen, and is fed into a sheet forming and dewatering apparatus to form a dewatered, fibrous web, which is dried to form the fibrous product.
