Abstract (en)
[origin: US6270626B1] The invention concerns a novel method for making paper based on sheet cellulose fibre, wherein a novel retention system comprising a suspension of bentonite and a cationic galactomannan is used to improve in particular the retention of the incorporated mineral fillers. The invention also concerns a method for making paper using a retention system which substantially improves draining.
