Abstract
A method of producing pulp of high light-scattering ability and low shive content by refining wood material. The wood material is subjected to a gas-phase sulphonation process prior to complete refinement of the wood material, suitably prior to the refinement as such. Prior to or after the sulphonation, the wood material is subjected to a treatment known per se, to introduce alkaline metal ions as counter ions to the acidic groups of the wood.
