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.
Claims11
A method for reducing the fibrillation tendency of lyocell fibre, comprising in a continuous process the steps of (1) applying to the fibre in never-dried state an aqueous solution comprising dissolved therein an inorganic alkali and a chemical reagent bearing a plurality of acrylamido groups, the average number of acrylamido groups per molecule of the chemical reagent in the solution being greater than 2.1, and (2) heating the fibre to which the chemical reagent has been applied to produce reaction between the fibre and the chemical reagent.
