A process is useful for manufacturing a storable, easily handled fibre mat (24) made of cellulose fibres (1) and thermoplastic fibres (10), in particular polyester fibres, and/or natural fibres of vegetable origin, and containing a thermosetting binder (5) made of plastic. During the application of heat and pressure and setting of the thermoplastic binder in a later step of the process, the fibre mat (24) can be compressed to form dimensionally stable pieces which possess uniform properties over their entire cross-section. For this purpose, the cellulose fibres (1) are impregnated with a solution of the thermosetting binder (5), preferably a phenol resin solution, and then dried; the dried cellulose fibres (6) are dry mixed with thermoplastic fibres (10), for example polyester fibres, and/or natural fibres of vegetable origin; a nonwoven (21) is made from the mixture of cellulose fibres (6) and thermoplastic fibres (10) and/or natural fibres of vegetable origin, and the nonwoven (21) is reinforced by needles in a needle machine (23). |
