FIELD: paper and pulp manufacturing.
SUBSTANCE: the present innovation deals with manufacturing paper being resistant to contamination and applied for manufacturing bills of exchange, shares, banknotes, savings certificates and others. Out of plant fibers one should form paper fabric to impregnate it with the composition that contains polyvinyl alcohol at weight concentration being under 8%, ammonium salt of titanium chelate and lactic acid. Paper fabric treated in gluing press or impregnation bath should be dried at 100°C, not less, passed through machine calender for providing the desired smoothness for further winding by rolling. The innovation increases paper resistance to contamination at keeping its high physico-mechanical properties.
EFFECT: higher efficiency of manufacturing.
