Learning Outcomes (valid 01.08.2018-31.07.2020): 

After the course the student

  • knows how wood fibres are isolated from the wood ‘matrix’
  • knows how the key commercially important vegetable fibres are isolated from the plant and processed into intermediate products
  • knows how regenerated cellulose fibres are manufactured
  • can describe the structure of the lignocellulosic fibre cell wall and knows how the structural organisation of the cell wall affects the key physical and mechanical properties of the fibre
  • is familiar with the properties of regenerated fibre and how this can be manipulated
  • is familiar with moisture sorption in cellulose-based fibres and how moisture affects the fibre properties
  • is familiar with how damage is induced in cellulose-based fibres and its effect upon their properties
  • knows about the manufacture of nanocellulose and is able to describe its properties and current and potential application areas
  • has knowledge on the chemical structure and reactivity of cell wall components

Content (valid 01.08.2018-31.07.2020): 

Isolation of wood and non-wood fibres from the plant material; cell wall structure of lignocellulosic fibres; chemical structure and most common chemical reactions of cell wall components; structure-property relationships of lignocellulosic fibres; sorption behaviour and effect on properties; fibre mechanics and modelling; defects in fibres and their effect on properties; dissolution of cellulose and manufacture of regenerated cellulose; structure and properties of regenerated cellulose; nanocellulose – isolation, characteristics and applications
