Abstract
Using amines as additives in alkaline pulping allows to improve delign ification rate and tearing strength compared to kraft pulps. These res ults can be explained first by the superbasic propeties of water-amine solutions and secondly by the amine properties of solvation to the ca rbohydrates of fibre cells. Solvation and swelling increase fibre flex ibility and tearing strength of pulps and papers obtained by alkaline pulping with amines.
