Abstract
A method for producing shaped bodies of fibrous materials using mineral fibers, cellulosic fibers, and zero fibers. The zero fibers are extremely thin and short cellulosic fibers produced either synthetically or from natural by-products from the cellulose industry. These bodies can be used as substitutes for asbestos fiber products, and display physical properties, such as resistance and rigidity, comparable to the asbestos products. The fibrous materials are produced using an aqueous dispersion of the mineral fibers, cellulose fibers, and zero fibers, whereafter the dispersion is de-watered, shaped and dried.
