1. 1. Adsorption of xylans on cellulosic fibres -Influence of xylan composition on adsorption characteristics and kraft pulp properties

   Författare :Tobias Köhnke; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Xylan; Hornification; Lignin-carbohydrate complexes; Cationization; Isolation; Softwood kraft pulp; Extraction; Adsorption;

   Sammanfattning : Xylans are polysaccharides present in large amounts in cell walls of vascular plants. They possess an inherent affinity to cellulose and will thus adsorb irreversibly on cellulose surfaces. LÄS MER

3. 2. Improving cellulose fibre properties by controlled adsorption of xylans

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Isolation; Lignin-carbohydrate complexes; Adsorption; Extraction; Tensile strength; Aggregation; Softwood kraft pulp; Cellulose fibre; Hornification; Xylan;

   Sammanfattning : Hemicelluloses are, together with cellulose and pectins, the polysaccharide constituents in the cell walls of higher plants. Xylans are the most common hemicelluloses, and are considered to be the second most abundant biopolymer in the plant kingdom. LÄS MER
