L. Jörgensen. The chemistry of pulp fibres. In Fundamentals of Papermaking Fibres, Trans. of the Ist Fund. Res. Symp. Cambridge, 1957, (F. Bolam, ed.), pp 107–128, FRC, Manchester, 2018.


Spruce pulps have been prepared by various processes – sulphite, bisulphite, sulphate and multistage processes such as `bisulphite-soda’ and ‘Sivola’ – over a wide yield range. The carbohydrate composition of the pulp fibres, their hemicellulose content, as well as the carbohydrates present in some of the hemicelluloses have been determined. Some of the papermaking properties of the pulp fibres are presented and the results discussed in relation to the chemistry of the pulp fibres.

The data on the composition, hemicellulose content and hemicellulose composition of birch sulphite, sulphate and neutral semi-chemical pulps are presented for a limited high yield range.
