Abstract

Process for the manufacture of non-woven articles, characterized in that it comprises precipitating a thermoplastic resin on asbestos fibers in dispersion in water, in the presence of 0.3 to 10% relative to the weight of the resin of a reaction product of a polyamide with epichlorohydrin, at a temperature between 40 and 100ºC, prepare an aqueous dispersion containing the coated asbestos fibers such as those obtained in the first stage, together with other fibrous materials; form a sheet by removing the water and then dry this sheet.
