A process for the manufacture of molded parts from fibrous material, particularly cellulose-containing fibers. A particulate binder is incorporated into a fiber filling after which the mixture is precompacted into a fiber mat which is subjected to a hot steam treatment and is finally molded into the finished part under pressure and heat. The binder consists of thermoplastic particles into which a blowing agent is incorporated by forming an alloy-like state which is activated prior to final molding of the part, preferably by means of hot steam treatment, and a binder which cross-links when exposed to heat applied to the surface of the particles.
