Abstract

A process for the manufacture of a swellable crosslinked carboxyalkylcellulose by treating cellulose or cellulose hydrate fibres or sheet with etherifying and crosslinking agents in an aqueous alkaline medium in excess, removing the excess and heating. The process may be carried out in apparatus comprising a reaction medium mixing and storage tank (6), a sieve drum washer (2) in which the reaction medium is contacted with the cellulose material, a padder (3) in which the excess medium is removed, and finally a heated sieve drum drier (5) or a sieve belt steamer (2). <IMAGE>
