Abstract
The present invention relates to a method for reducing the fibrillation tendency of lyocell fibre. Never-dried fibre is treated by an inorganic alkali solution and a chemical reagent having an average of greater than 2.1 acrylamido groups, and then heated. This method produces cellulose materials with a smooth white appearance resistant to creasing in the wet state.
