| description | In the method for the manufacture of a paper pulp for currency use from a stock comprising textile fibers, the operations of boiling, bleaching, chopping, breaking, cutting and washing of the textile fibers are performed in at least one treatment machine (10, 40) of the type having two co-rotating screws, in a plurality of phases taking place successively and continuously. The operations include a phase of feeding and mixing the stock with water, at least oen compression phase, at least one phase of shearing of the textile fibers, at least one phase of treatment of introduction of boiling and bleaching reagents, at least one phase of washing of the bleached pulp by introduction of washing water, and a phase of transferring and evacuating the bleached and washed pulp. |
