Beschreibungen/Notizen

• The hemicellulose content of pulp is dependent on different factors, such as the wood species, the conditions with cooking and bleaching harmonised with the application. In addition to the hemicellulose content, a special interest for the valuation of pulp and the decision of arrangements of the production process is the hemicellulose distribution across the cell wall layers and the influence of several process stages on the hemicellulose distribution across the cell wall layers. The investigations were carried out on dissolving pulp and paper grade pulp. For paper grade pulp, the influence of separate bleaching steps and several bleaching sequences on the distribution of hemicellulose across the cell wall were investigated. Regarding the selected dissolving pulps which were produced according to an acid bisulphite process and a pre‐hydrolysis sulphate process the influence of the cooking process on the hemicellulose distribution across the cell wall layers was of a special interest.
