1. Dissolving pulp : Multivariate Characterisation and Analysis of Reactivity and Spectroscopic Properties
Abstract : Various chemical properties can be used to characterise dissolving pulp. The quality of the pulp must be carefully controlled to ensure that it meets the requirements for its intended use and the further processes to be applied. READ MORE

2. Dissolution of cellulose for textile fibre applications
Abstract : This thesis forms part of a project with the objective of developing and implementing a novel, wood-based, process for the industrial production of cellulose textile fibres. This new process should not only be cost effective but also have far less environmental impact then current processes. READ MORE

3. Activation of dissolving pulps prior to viscose preparation
Abstract : The conventional viscose manufacturing process is a mature process that needs to be improved with respect to its environmental impact and its production cost structure. Therefore a research study has been done with the aim to improve the reactivity of the dissolving pulp used, in order to reduce the chemical demand in the viscose process and thus reduce the cost and indirectly the environmental impact.

4. Carbon fibres from lignin-cellulose precursors
Abstract : It is in the nature of the human species to find solutions of complex technical problems and always strive for improvements. The development of new materials is not an exception. One of the many man-made materials is carbon fibre (CF). READ MORE

5. Nanocomposites made from nanoporous cellulose fibre
Abstract : This thesis explores how to use the dry nanoporous structure of cellulosic fibres in new types of composite materials. A large effort was also given on how to correctly characterize the structure of fibres where the wet structure has been preserved also in the dry state. READ MORE
