FIELD: paper-and-pulp industry.
SUBSTANCE: process of manufacturing cellulose products such as paper articles is accomplished by simultaneously or continuously adding at least one aluminum compound and at least one water-soluble silicate, in particular at least one product of reaction of monovalent cation silicate with bivalent metal ions, to fluid cellulose pulp such as paper pulp. Compositions are also described comprising at least one aluminum compound and at least one water-soluble metal silicate and cellulose products including at least one water-soluble metal silicate complex.
EFFECT: improved retention and drainage allowing manufacture of high-quality cellulose products.
