| Abstract | (21) Appl. No.: 12/727,299 The invention provides a method of producing paper with a y x9 higher proportion of mineral filler particles than is otherwise be possible without the expected loss in paper strength by preflocculating the filler particles. The method allows for the use of the greater amount of filler particles by coating at least some of the filler particles with a material that prevents the (51) Int. Cl. filler materials form adhering to a strength additive. The D2 IIH 7/45 (2006.01) strength additive holds the paper fibers together tightly and is D2 IIHI 23/00 (2006.01) not wasted on the filler particles. (22) Filed: Mar. 19, 2010 |
