The present invention relates to a paper comprising forming a cellulose suspension, agglomerating the suspension, mechanically shearing the suspension, optionally reaggregating the suspension, discharging the suspension onto a screen, forming a sheet, and then drying the sheet. Or to a process for the manufacture of cardboard, wherein the suspension is agglomerated and / or reaggregated by introducing a water soluble polymer having an intrinsic viscosity greater than 3 dl / g into the suspension, wherein the flow of tan delta at 0.005 Hz of the water soluble polymer A method characterized in that the mechanical vibrations exceed 1.1. This method has the advantage of improving retention. |
