<p>1. A method of manufacturing a sheet of paper containing latex, in which a pulp is prepared from fibres and latex particles and subsequently converted into a sheet, the pulp being prepared as follows : the chosen fibrous material is suspended in water, the Zeta potential of the suspension is measured, the pH of the suspension is adjusted to a value near the pH of the aqueous latex suspension to be added subsequently, an aqueous solution is formed from a cross-linking agent having an electric charge of opposite polarity to that of the suspension of fibres, the concentration of the solution of cross-linking agent is adjusted so that after the aforementioned solution and the latex suspension have been added to the fibrous material, the Zeta potential of the resulting mixture is practically the same as that of the suspension of fibrous material, the pH of the cross-linking agent solution is adjusted to a value near that of the suspension of fibres and the latex suspension, the solution of cross-linking agent is added to the aqueous suspension of fibres, and the aqueous suspension of latex is added.</p> |
