Process for the production of a cellulosic product

摘要

The present invention pertains to a process for the production of a cellulosic product which comprises (i) providing an aqueous suspension containing cellulosic fibres and, optionally, a filler; (ii) adding to the suspension a clay having 3R 1 stacking and interlayers which comprise hydroxide; and (iii) dewatering the obtained suspension. Further, it pertains to the use of a clay having 3R 1 stacking and interlayers which comprise hydroxide for removing disturbing and detrimental substances such as pitch and stickies from an aqueous cellulosic pulp suspension.
