An aqueous solution of an alkali metal hydroxide, preferably sodium hydroxide, containing from 0.2 to 3.85 percent by weight hydroxide ions is applied to a never-dried cellulosic article, for example fibre or film, being produced by the lyocell process. The method of the invention confers increased dyability on the cellulosic article, and it may also confer increased absorbency, increased whiteness and/or reduced yellowness thereon.
