Process for preparing high wet-strength paper |
| abstract |
Process for the production of paper with high wet strength, in which melamine-formaldehyde resin colloids are added to the paper pulp, which is obtained by continuously mixing a 40 to 80% strength aqueous solution of an optionally modified melamine with water and acid in a mixing zone under turbulent flow A temperature of 40 to 110 ° C, a pH of 2 to 4 and a residence time from the mixing zone to the point of addition to the paper stock of 1 to 300 seconds are available, the solids content of the melamine-formaldehyde resin colloid solution being about 5 to 20 Is wt .-%, and then dewatered the paper stock on the paper machine. |
