  1. 1. Testing and Evaluation of Interfibre Joint Strength under Mixed-Mode Loading

    Författare :Mikael S. Magnusson; Sören Östlund; Lars Wågberg; Mikael Nygårds; Kristofer Gamstedt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interfibre joint; fibre-fibre bonding; paper strength;

    Sammanfattning : The failure properties of interfibre bonds are the key for the build-up of strength in fibrous materials such as paper and paperboard. In order to tailor the properties of such materials by chemical or mechanical treatments and to learn how such modifications influence the properties at a microscopic level, direct measurement of individual fibre--fibre crosses are typically performed.

  3. 2. The mechanisms of edge wicking in retortable paperboard

    Författare :Helena Tufvesson; Lars Wågberg; Agne Sewerin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : This thesis reports on an investigation of the mechanisms of edge wicking in retortable paperboard. Retortable board is used for packaging preserved food, a process which requires that the package and its contents be sterilised by exposure to high temperature steam for up to three hours. LÄS MER

  4. 3. High strength paper from high yield pulps by means of hot-pressing

    Författare :Tove Joelsson; Per Engstrand; Gunilla Pettersson; Anna Svedberg; Samuel Schabel; Mittuniversitetet; []
    Nyckelord :high yield pulp; hot-pressing; lignin; paper properties; wet strength;

    Sammanfattning : AbstractHigh Yield Pulp (HYP), i.e. TMP, SGW or CTMP, is normally used in printing papers (News, SC and LWC) or in a middle layer on cardboard i.e. LÄS MER
