    • The invention relates to a method for treating cellulose-containing fibers or planar structures containing cellulose-containing fibers with a combination of: 1) compounds comprising at least two primary amine groups and 2) compounds comprising at least one β-ketocarbonyl group. The compounds (2) contain β-carbonyl groups of the general formula -Y-C(O)-CHR4-C(O)-CH2R4 or its tautomeric enol form of formula -Y-C(O)-CR4=C(CH2R4)-OH wherein Y is -O- or -NR²-, preferably -O-, R² represents a hydrogen atom or a monovalent hydrocarbon group with 1 to 30 C atoms, preferably a hydrogen atom, and R4 represents a hydrogen atom or a monovalent hydrocarbon group with 1 to 18 C atoms, preferably a hydrogen atom. The treatment can be carried out by metering compounds (1) and (2) - either individually in successive steps or together as a premix from (1) and (2) - to the aqueous cellulose-containing fibrous pulp, from which paper products are produced, or by spraying the compounds (1) and (2) - either individually in successive spraying steps or together as a premix from (1) and (2) - onto the paper products.
    • 本发明涉及一种用包含至少两个伯胺基团的化合物和2)包含至少一个β-酮羰基基团的化合物的组合处理含纤维素纤维或含纤维素纤维的平面结构的方法。 化合物(2)含有通式-YC(O)-CHR4-C(O)-CH2R4或其式-YC(O)-CR4 = C(CH2R4)-OH的互变异构烯醇式的β-羰基,其中 Y是-O-或-NR 2 - ,优选-O-,R 2代表氢原子或具有1-30个C原子的一价烃基,优选氢原子,并且R 4代表氢原子或具有1个碳原子的一价烃基 至18个C原子,优选氢原子。 处理可以通过计量化合物(1)和(2) - 单独地连续步骤或一起作为(1)和(2)的预混合物 - 将含纤维素的纤维纸浆计量加入到纸浆产品中 或者通过喷雾化合物(1)和(2) - 单独地在连续的喷雾步骤中或者作为(1)和(2)的预混物一起喷雾到纸产品上。
