METHOD FOR PRODUCING A MULTI-LAYER FIBROUS SUPPORT BY FRACTIONATION AND STRATIFICATION |
摘要 |
The invention relates to a method for producing a multi-layer fibrous support, comprising the following steps: a paper pulp comprising fibres and fines is agitated so as to form a fibrous suspension; the fibrous suspension is fractionated into a first main fraction of fibres and a second main fraction of fines; the resulting main fraction of fibres is fractionated by a hydrocyclone in such a way as to form the following two secondary fractions: a fraction of binding fibres; a fraction of coarse fibres; and a multi-layer fibrous support is formed by stratification of the main fraction of fines and the secondary fractions of fibres, or the mixtures thereof. |
