he biggest issue facing our planet is climate change, caused

mainly by emissions generated by combustion of fossil fuels by

industry, automobiles and heating of buildings. Tomitigate climate

change, we should make extensive efforts to find economically

sustainable solutions for the use of wood, while at the same time

planting more trees than that we cut. At present the large scale

uses of wood are: building materials, paper and textile. This study

deals with a new way of making functional cellulose fibers, which

can be made into filaments, smart textiles, high value cellulose

biomaterials, such as superhydrophobic fibers and fibers of high

tenacity, as well as high value dyed fibers. In the novel process,

kraftfibers are chemicallymodified inwater andmade into a dope

by dissolving it in an alkaline solution. The dissolved cellulose is

regenerated in the acid bath of a spinneret, producing cellulose

filaments, which can be further functionalized if desired. Trials on

a demonstration spinneret show that such fibers can be spun at

industriallyspeedsanddrawingrates.Propertiesofthenovelfibers,

such as tenacity, elongation and water take-up are compared to

those of rayon and cotton.

Speaker Biography

Theo van de Ven obtained the equivalent of a

and

. (in physical and colloid

chemistry with a minor in theoretical physics) from the University of Utrecht, Holland,

and obtained his PhD from McGill University. After a 2 year postdoc at the University

of Sydney, Australia, he returned to McGill, where he is now a Full Professor in the

Department of Chemistry, where he holds the Sir William C Macdonald Chair in

Chemistry. He is an expert in colloid and surface chemistry, both in fundamental

aspects and applied to papermaking and cellulosic materials. He has published over

400 papers in the scientific literature, among which a book (“Colloidal Hydrodynamics”,

Acad. Press 1989) and several book chapters. He was awarded with ACS Award in

Colloid and Surface Science and was elected as Fellow of the Royal Society of Canada.
