1. 6. Preparation of Electroconductive Paper by Deposition of Conducting Polymer

   Författare :Elson Montibon; Magnus Lestelius; Lars Järnström; Agne Swerin; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electroconductive paper; conducting polymer; adsorption; coating; organic solvents; bulk conductivity; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : The thesis describes an investigation into the interaction between the conducting polymer and cellulosic materials, and the preparation of electroconductive paper. The adsorption behavior of the conducting polymer onto cellulosic materials was characterized. LÄS MER

3. 7. New methods for evaluation of tissue creping and the importance of coating, paper and adhesion

   Författare :Jonna Boudreau; Christophe Barbier; Ulf Germgård; Sverker Albertsson; Robert Pelton; Karlstads universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 8. Barrier Properties of greaseproof paper

   Författare :Henrik Kjellgren; Gunnar Engström; Lennart Stolpe; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Greaseproof papers; Air permeance; Coatings; Chitosan; Oxygen Barrier properties; Chemical Engineering; Kemiteknik; Chemical engineering;

   Sammanfattning : The barrier properties of greaseproof paper are achieved by extensive beating of the fibres. This treatment results in high costs for energy, both as beating energy and drying energy. A full-scale trial has been performed to investigate the role of the pulp with respect to energy demand and the barrier properties of the final papers. LÄS MER

5. 9. Properties of modified starches and their use in the surface treatment of paper

   Författare :Anna Jonhed; Lars Järnström; Ann-Charlotte Eliasson; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface treatment of paper; hydrophobically modified starches; temperature-responsive starch; inclusion complexes; barrier properties; Surface engineering; Ytbehandlingsteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : The papermaking industry uses a large amount of starch each year, both as a wet-end additive and as a rheological modifier in surface sizing and coating colors. It is important to be able to reduce the amount of chemicals used in the papermaking and surface treatment process, to reduce costs and to make the process even more efficient. LÄS MER

7. 10. Some aspects on strength properties in paper composed of different pulps

   Författare :Hanna Karlsson; Luciano Beghello; Lars Nilsson; Lennart Stolpe; Øyvind Gregersen; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper strength; reinforcement; multilayer; stratified; handsheet former; abaca; southern pine; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : For papermakers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are desirable both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging and light-weight building material. LÄS MER
