<p>In a process for producing fibrous mats from starting material for compression moulded articles, fiberized waste materials are mixed with thermoplastic and/or duroplastic binders, the mixture is spread on to an air-permeable conveyor belt to form a first fleece layer, a fabric is placed loosely on said fleece layer, then a second fleece layer is spread on the fabric or lattice and subsequently the composite fleece is compressed at elevated temperature and under pressure to form a transportable mat from which individual moulded articles can be produced by compression moulding at temperatures between 180 DEG and 220 DEG C., the fabric being sprayed with a liquid phase duroplastic finish prior to its deposition. In this way the fabric finish composition can be matched to the binder for the fibres, so that completely satisfactory binding or tying in of the fabric into the fleece layers can be achieved.</p> |
