Abstract

THE PRESENT INVENTION PERTAINS TO A METHOD HAVING INCREASED SELECTIVELY FOR BLEACHING LIGNOCELLULOSIC PULP HAVING A HIGH CONSISTENCY FROM A FIRST GE BRIGHTNESS TO A SECOND, HIGHER GE BRIGHTNESS WHICH COMPRISES THE STEPS OF (A) FLUFFING THE HIGH CONSISTENCY PULP HAVING THE FIRST GE BRIGHTNESS TO A SPECIFIC SURFACE AREA OF AT LEAST ABOUT 90M?/KG; AND (B) CONTACTING THE FLUFFED PULP WITH A GASEOUS BLEACHING AGENT TO FORM A BLEACHED PULP HAVING THE SECOND, HIGHER GE BRIGHTNESS. THE PRESENT INVENTION ALSO PERTAINS TO A BLEACHED LIGNOCELLULOSIC PULP PREPARED BY THE METHOD OF THE PRESENT INVENTION.
