Abstract (en)
[origin: EP0009322A1] An absorbent paper is formed from 5-95% by weight of insoluble amino-formaldehyde resin fibres of 1-10 mm length and 1-30 mu m diameter and correspondingly 95-5% cellulose pulp. Where the Canadian Standard Freeness of the cellulose pulp is below 310 x + 140 ml. (where x is the proportion of lignin free pulp in the cellulose pulp) the proportion of amino-formaldehyde fibres is such that the blend has a freeness above 220 x + 400 ml. The paper may be made by forming an aqueous slurry of the fibrous constituents into sheet form followed by dewatering.
