Appl. No.:

7/976987

Inventors:

Robert W. Novak - Lisle IL

Assignee:

Nalco Chemical Company - Naperville IL

International Classification:

D21H 1734

US Classification:

1621682

Abstract:

The invention provides a method for improving the retention of mineral fillers and cellulose fibers on a cellulosic fiber sheet. The method comprising the steps of preparing a cellulose pulp slurry; adding before a shearing step an effective amount of a copolymer flocculant to the cellulose pulp slurry, the copolymer flocculant is a high molecular weight cationic copolymer of acrylamide and diallyl dimethyl ammonium chloride, the flocculant copolymer should contain from about 20 to about 60 mole percent diallyl dimethyl ammonium chloride mer units. After a shearing step adding an effective amount of a high molecular weight water-soluble anionic flocculant. A cellulosic fiber sheet is then formed from the cellulose pulp slurry which includes both the copolymer flocculant and anionic flocculant.
