Methodologies providing new insights into the fundamentals of the pulping process

Today’s knowledge of what happens concerning the kinetics and other phenomena in the digester during the pulping process is mainly the result of the use of inductive methods. Based on these methods, generalised models have been formulated that are applied for process development as well as for industrial process optimisation.  Recent studies (e.g., Mattsson et […]

Magnetic nanopaper

This project is focused on production and development of magnetic nanopaper with ferrimagnetic properties. Cellulose nanofibrils (CNFs) are used as a stiff and strong matrix of natural origin, while ferrimagnatic nanoparticles of SrFe12O19 are added to bring in the functionality. Nanopaper is prepared by spray coating technique which is simple to handle and to upscale.

Processability of modified fibres for complex shaped parts

There is a drive towards the use of single-component materials in different applications, for example in opening and closure of packaging products and in single use plastics (SUP). This opens up the possible use of cellulose-based products, but increases the demand for new modification strategies for fibres. Modifications aiming at improving their processability and final

Macro- and microscopic deformability of fiber networks made from softwood fibres

Holmen is a major Swedish producer of paper and board products. Most of these products are based on softwood fibres. During converting of the products, they are plastically deformed in folding, creasing or embossing operations. This deformation occurs both in a macro and microscale. It is therefore important to understand the influence of the raw
