Definitions
- the invention relates to a process for the production of paper, cardboard and cardboard by dewatering a paper stock in the presence of polymers.
- paper consists essentially of fibers consisting of wood and / or cellulose, and optionally of mineral fillers, in particular calcium carbonate and / or aluminum silicate, and that the essential process in papermaking consists of a separation these fibers and fillers from a dilute aqueous
- cationic water-soluble polymers or, in other words, cationic polyelectrolytes or polycations with a preferably medium or high molecular mass.
- These products are added to the very dilute pulp before the sheet of paper is created on the sieve. Depending on their composition, they cause e.g. more fine material remains on the sieve, or that the water on the sieve is separated more quickly, or that certain substances are fixed to the paper fibers and thus do not get into the white water, whereby the cleanliness of the white water is paramount in the latter case can, as well as the effect of the fixed substances, e.g.
- polycations can also increase the strength of the paper or give the paper improved residual strength when wet. In order to obtain this so-called wet strength, however, polycations are generally used which additionally carry reactive groups which react with the paper constituents or with themselves with the formation of networks and because of the resulting covalent bonds make the paper more resistant to water.
- the polycations used according to the prior art for the stated purposes are almost exclusively polymers of synthetic origin, i.e. for products on a petrochemical basis.
- An essential exception, however, are the cationic starches, which result from the reaction of a plant-based raw material with a synthetic cationizing agent.
- other polysaccharides modified with synthetic cationizing agents are used in papermaking, e.g. cationic guar flour.
- the literature also describes the polysaccharide chitosan, which is obtained from shellfish by chemical reaction with chitin, as a cationic paper aid, but no permanent practical application has been disclosed to date.
- products based on vegetable or animal raw materials often have the advantage that they are more readily biodegradable when reintroduced into the natural cycle.
- the use of plant-based raw materials also helps to conserve fossil resources and reduce carbon dioxide emissions.
- the polycations based on renewable raw materials that have so far been used as paper chemicals are exclusively polysaccharides with a very narrow profile of activity.
- the main cationic starches used are used to increase the dry strength of the paper and to a lesser extent as a retention agent.
- the invention is based on the object of providing further substances based on natural raw materials which, for example, fix anionic substances in paper during paper production and which improve the retention of fillers.

- Example 7 The procedure is as described in Example 7, but with the difference that the two cationic starches I and II are used as comparison products.
- the test results are shown in Table 8. They show that the use of lysine polycondesates in papermaking can significantly increase the drainage and retention effectiveness of high molecular weight cationic polyacrylamides, and more so than with commercially available cationic starches.
- Example 8 The procedure is as described in Example 8, but with the difference that no high molecular weight cationic polyacrylamide is used as the retention agent, but only different amounts of the lysine polycondensates.
- the test results are the See table 9. They show that lysine polycondensates have a pronounced drainage and retention activity in papermaking even when used alone.
- Example 10 The procedure is as described in Example 9, but with the difference that cationic starches are also tested as comparative products.
- the test results are shown in Table 10. They show that lysine polycondensates have a significantly better dewatering and retention activity than cationic starches in paper production even when used alone.
