Kraft pulp produced at Kappa number approximately to 85 was fractionated. Thereafter, the coarse fibres enriched fraction was sulphonated. Sulphonation was carried out to enhance the refinability of the coarse fibres enriched fraction. The refinability of the pulp was evaluated using PFI mill.enFractionationCoarse fibres enriched fractionSack paperConsistencySulphonationRefiningStrength propertiesFractionation of high Kappa number kraft pulps of the South African softwoods and sulfonating of coarse fibre enriched fraction for production of sack paperArticleJohakimu, J.
