| 发明名称 | Fixative composition, thick stock composition and process for fixating hydrophobic and/or anionic substances on fibres | ||
| 摘要 | The present invention relates to a fixative composition and process for reducing hydrophobic and/or anionic substances in fiber-containing stock for making of paper, board or the like. The composition comprises a synthetic cationic polymer, which has a charge density of 3.0-24 meq/g, and a cationic non-degraded starch, which has charge density of 0.5-3.0 meq/g. The invention relates also to thick stock composition comprising fibers and a fixative composition according to the invention. | ||
