Method of producing paper, paperboard and cardboard |
| abstract |
The invention relates to a method of producing paper, paperboard and cardboard by dewatering a paper material in the presence of condensation products of basic amino acids and sheet forming. The inventive method especially uses homo-and co-condensation products of lysine and the cross-linked condensation products obtained therefrom by reaction with cross-linking agents in an amount of from 0.01 to 5 wt.- % based on the dry paper material to increase the dry and wet strength and the absorbency of paper. These materials are also used to fixate anionic dyes and interfering substances in the paper, to increase the dewatering rate and the retention and the efficacy of synthetic anionic and cationic retention agents in the production of paper, paperboard and cardboard by dewatering the paper material and sheet forming. |
