Regenerated Cellulose and Cellulose Derivatives

Target audience and purpose

Participants from industry are welcome to take part in the course together with PhD students but without the possibility of examination and credits.

Recommended prior knowledge 

There are no formal eligibility requirements for participating in contract education at university level. The employer decides who is suitable to participate. However, the course participant should have knowledge in chemistry and basic knowledge in cellulose technology. The course is given entirely in English.

Course content

The aim of the course is that the participants 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.

• 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 arrange, this is not mandatory in the course.

Learning objectives

After completed course the participant 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
