PRODUCTION FOR MOTTLED PAPER |
摘要 |
A method of producing a two-colour mottle-effect patterned paper comprises the steps of colouring a papermaking stock by means of a first dye formulation, draining the resulting coloured stock through a papermaking wire to produce a dyed wet paper web, subjecting the web to pressure, applying a second dye formulation to the paper web, said second dye formulation being of a different hue from the first dye formulation, and drying the web. The web is preferably subjected to pressure by passage through a smoothing press nip before passing to the drying section of the papermachine. The smoothing press can be one of the presses of the press section of the papermachine, run in unfelted mode. The second dye formulation is preferably applied at the papermachine size press or by spraying.
