Abstract (en)
[origin: FR2764614A1] The invention concerns a method for the continuous preparation of paper pulp from a raw material consisting of lignocellulose textile fibres, consisting in cutting the textile fibres, separating the textile fibres from foreign bodies, carrying out a continuous pre-washing, bleaching the textile fibres in a first treating machine (10) to obtain a first pre-bleached pulp, continuing the bleaching in a first capacity of latency (41), continuously washing and bleaching the pulp in a second treating machine (50), continuing the bleaching in a second capacity of latency (84), diluting the pulp in a first dilution tank (85), dewatering and pressing the pulp and diluting the pulp in a second dilution tank (94). The invention also concerns an installation for implementing the method.
