Abstract (en)
[origin: WO2014044475A1] The invention relates to a method for the fractionation of a fibre suspension (1) produced from used paper or from broke of a machine for the production of multi-layer fibre webs, wherein a long fibre fraction (11) with predominantly long fibres and a short fibre fraction (12) with predominantly short fibres are formed. The recycling efficiency is improved as a result of the Kappa number of the long fibre fraction (11) being lower than that of the fibre suspension (1).
