Abstract
The invention relates to a method at the production of absorbent cellulose pulp, so-called fluff. By using certain nonionic fatty acid esters in combination with cationic retention agents, good disintegration properties of the cellulose pulp is obtained and the fluff which is obtained after dry-defibration has fast liquid absorption. The esters, which are used, are partially fatty acid esters of polyvalent alcohols, and as cationic retention agents quaternary ammonium compounds can e.g. be used.
