Mechanics of load-bearing sustainable materials

Novel load-bearing materials from forest, e.g., paper fibre materials, cross-laminated timber (CLT), etc, are important materials for bioeconomy as they can store carbon for long-term commitment, but they are complex in nature having anisotropy, environmental sensitivity and other factors that affects their mechanical performance. This project focus on further research on mechanical characterization of such […]

Modification of cellulose for paper making application

Cellulose is the most abundant polysaccharide in nature; its renewability, sustainability, and biodegradability have brought cellulose more and more attentions all over the world. In particular, they have been acknowledged as having huge potential in pulp and paper technology. It is also possible to modify them using various modification techniques in order to expand the

Förhorning av träfibrer

Projektet går ut på att genom experimentella studier bygga upp en kunskap kring förhorning av komponenterna i träfibrer. Förhorning är ett fenomen där, i nuläget praktiskt sett irreversibla, processer i samband med torkning förändrar fibrernas svällning och flexibilitet och därmed bindningsförmåga. Bindningsförmågan till andra fibrer har stor inverkan på hur starka fibernätverk kan skapas och

Energy efficiency and modelling of vacuum dewatering in modern tissue machines

The project is a research coproduction between the research environment Pro2BE at Karlstad University, Valmet and Albany International about energy efficiency of tissue production. The project is aimed at acquiring deeper knowledge about tissue vacuum dewatering and at modelling vacuum dewatering during tissue production, both with a conventional tissue manufacturing method (DCT) and with Through
