Regenerated Cellulose and Cellulose Derivatives

A broad overview of the global dissolving pulp capacities

Course content:

The aim of the course is that the students should aquire a broad overview of the dissolving pulp production and the market for cellulose derivatives and regenerated cellulose. The course covers cellulose structures in detail and the characteristics of dissolving pulps. Process technology for producing cellulose derivatives will then follow as well as for viscose processes and the Lyocell process will including fiber spinning technologies. The course includes lectures, a visit to a viscose manufacturer, group assignments and a written examination.

  • Cellulose structures
  • Dissolving pulps
  • Viscose- and Lyocell processes, fiber spinning
  • CMC-chemistry, process and market
  • Other cellulose derivatives
  • Current development and research within the field

A study visit to a viscose mill will be arranged (this is not mandatory in the course).

Learning objectives:

After completed course the research education student should be able to:

  • discuss important cellulose derivative and viscose technology aspects in a correct terminology,
  • relate the results of measured parameters to different product quality aspects,
  • describe the most important processes for manufacturing of regenerated cellulose and cellulose derivatives
  •  demonstrate an understanding of the pros and cons of regenerated cellulose and cellulose derivatives compared with other materials

The examination will be in form of a written home exam, a group assignment and a follow-up seminar.
