Regenerated Cellulose and Cellulose Derivatives
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 […]
Paper Water Interactions
Moisture sorption and swelling Water sorption and paper structure Influence of temperature and water on mechanical properties Interactions of fibres and water – product demands Influence of moisture on mechanosorptive creep
Packaging materials
Packaging will be presented and discussed from the performance perspective, in certain applications with a focus on food stuffs, including product safety (especially materials and barriers perspective), economics/services (systems perspective), communications and marketing, logistics, design and sustainability. Materials used in packaging, and some of the converting processes, will be covered, such as glass, metals, polymers […]

Mechanics of fibre networks and materials
There is a wide class of materials where a fiber network is the main load-carrying component. This class encompasses paper, paperboard, tissue and many biopolymers. These materials are known to have outstanding stiffness-to-mass ratio which is one of the reasons they are so abandon in nature. We will study this class of materials by considering […]
Regenerated Cellulose and Cellulose Derivatives
The course will be similar to the course given 2019 and course details will be updated. The course will give the students a broad overview of the global dissolving pulp capacities and the market for cellulose derivatives and regenerated cellulose. The students will get a deep insight into the characteristics of dissolving pulps. The cellulose […]
