  1. 1. Fibre/fibre joints : Their characterization and influence on different paper strength properties

    University dissertation from Stockholm : KTH

    Author : Annsofie Torgnysdotter; Mittuniversitetet.; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Abstract : The main goal of this work was to gain knowledge of how to process the fibres for a certain enduse purpose. To reach this knowledge it must be clarified how different fibre properties, mechanical and chemical as well as surface and bulk properties, will influence the physical properties of the formed paper.

  3. 3. Formation and properties of polyelectrolyte multilayers on wood fibres  influence on paper strength and fibre wettability

    University dissertation from Stockholm : KTH

    Author : Rikard Lingström; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polyelectrolyte; multilayer; adsorption; reflectance; contact angle; dynamics; paper; mechanical properties; individual; wood fibre; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : The work in this licentiate thesis examines the adsorption of polyelectrolyte multilayers (PEM) onto wood fibres as a new way to influence the properties of the fibre surfaces and hence the fibres. Fundamental aspects of PEM formation on wood fibres have been studied, and discussed in terms of paper strength and wood fibre wettability. READ MORE

  4. 4. Renewable composites prepared from biobased thermoset resins

    University dissertation from Göteborg : Chalmers tekniska högskola
