Abstract

A method of fixing cellulose fibres and rendering them dimensionally stable is described. The cellulose fibres are comprised in a material containing cellulose fibres, preferably a paper material. The method is characterised by first treating the cellulose fibres with a carboxylic acid, preferably in combination with an inorganic acid, such as sulphuric acid, and thereafter with a polyethylene glycol which is then cross-linked by means of a cross-linking agent. The contents of carboxylic acid preferably are about 3-15 % by weight, calculated on dry cellulose fibres, and the contents of polyethylene glycol preferably are about 3-15 % by weight, calculated on dry cellulose fibres. The carboxylic acid preferably is acetic acid and the polyethylene glycol preferably has a molecular weight of about 200-400. In the treatment of paper material the carboxylic acid and the polyethylene glycol may be added to the stock, the carboxylic acid being added first and the polyethylene glycol about 1-30 min thereafter.
