| titleOfInvention | Method of increasing retention and drainage of filling components in paper making furnish by enhancing additive pretreatment |
| abstract | A method of increasing retention and drainage of filling components in a paper making furnish in a paper making process comprises: a) making a slurry of filling components and adjusting the pH of the slurry so that the pH of the slurry is from 4.5 to 6.5; b) treating the slurry with from 0.003 to 2.0% by weight of phenol-formaldehyde resins, tannin extracts, naphthoyl-formaldehyde condensates, poly(para-vinyl phenol) and mixtures thereof to form a pretreated filling component slurry; c) adding to the furnish the pretreated slurry of step b) and then d) adding to the furnish from 0.00 to 5% by weight of an anionic or cationic polymeric flocculant having a molecular weight of 500,000; Whereby the retention and drainage of the filling components in the paper making furnish are increased. |
