  2. 1. New methods for evaluation of tissue creping and the importance of coating, paper and adhesion

    Author : Jonna Boudreau; Christophe Barbier; Ulf Germgård; Sverker Albertsson; Robert Pelton; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue; creping; paper adhesion; Tissue paper; creping; paper adhesion; coating layer; adhesives; Yankee cylinder; crepe structure; wavelength measurements; Chemical Engineering; Kemiteknik;

    Abstract : The creping process and the conditions on the Yankee cylinder dryer are key factors in a tissue paper mill, and they therefore need to be kept under good control in order to maintain a high and uniform quality. To this end it would be valuable to be able to make on-line measurements of Yankee coating thickness as well as the crepe structure of the tissue paper. READ MORE

  4. 2. Tailored adhesion of PISA-latexes for cellulose modification and new materials

    Author : Joakim Engström; Eva Malmström; Robert Pelton; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PISA; latex; RAFT; Cellulose Nanofibrils; Cellulose Nanocrystals; Nanocomposites; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : This thesis is focused on applying modification chemistry to already known cellulosic substrates from wood (i.e. cellulose nanofibrils, CNFs, and cellulose nanocrystals, CNCs). READ MORE

  5. 3. Polyelectrolyte Complexes : Their Characterization and use for Modification of Wood Fibre Surfaces

    Author : Linda Gärdlund; Lars Wågberg; Robert Pelton; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik; Cellulosa- och pappersteknik; Chemical engineering;

    Abstract : For economical reasons filler particles and less expensive fibre raw materials are more frequently used in papermaking. This influences the mechanical properties of the formed papers in a negative way and it is therefore necessary to add strength-enhancing agents to the papermaking furnish. READ MORE

  6. 4. Interfacial Properties of Biomacromolecular Model Systems: Surface Forces and Nanotribology

    Author : Niklas Nordgren; Mark Rutland; Harry Brumer III; Robert Pelton; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; afm; surface force; friction; composite material; model surface; quartz crystal microbalance; dissipation; cellulose; xyloglucan; chitosan; colloidal probe; nanotribology; biomimetic; enzymatic; polysaccharide; graft; fiber; thiol; spring constant; calibration; lubrication; polyion; responsive.; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : The nanotribology, adhesion and related interfacial properties of biomacromolecular systems have been studied.  The aim was to elucidate the role of physisorbed and chemically grafted bio-polymers implicated as mediators for cellulose based processing and material design. READ MORE
