Abstract of the Disclosure A cellulose material for absorbent sanitary products is provided which contains a cellulose derivative which is either a cellulose ether or a cellulose ester in fibre form having an average substitution degree of no more than 0.40 in which the fibres burst during drying so that their surfaces are enlarged. This material is manufactured by bringing the cellulose derivative into a swollen state, fixing it in the swollen state and thereafter drying it and removing a major amount of swelling agent while retaining the material in the swollen structure and preventing shrinkage. An apparatus is disclosed which is specially adapted for the carrying out of this method.
