<p>Summary: Process of Molded Parts from Fibrous Material and Fiber Mat for the Manufacture of Molded Parts A process for the manufacture of molded parts from fibrous material, in particular cellulosic fibers, is described. For this purpose a particulate binding agent is introduced into a fiber fill, the mixture then precompressed into a fiber mat, subsequently subjected to high-temperature steaming and finally, after preforming as the case may be, molded into the final molded part under the influence of pressure and heat. The binding agent consists of thermoplastic particles incorporating a foaming agent in a state analogous to an alloy which is activated before the molding of the final molded part, preferably by hightemperature steaming, and of a binding agent that cross-links under heat and which is deposited on the particles in the form of a layer.</p> |
