Research of special purpose paper energy parameters influence on its anti-soiling properties. — 2011. — № 4(34). — pp. 72—79.
     All the stages of deterioration of banknotes in circulation include interaction of banknote paper base with soil, predomination majority of which are: soluble, emulsified, dispersed or suspended soil, when particles are dispensed in water or oil environment. That is why adhesion mechanism plays important role in forming of surface-contaminant layer.
     Purpose of this work was to investigate mechanism of contaminant adhesion on the special purpose paper surface.
     Paper surface energy parameters for paper of the Arjo Wiggins, which have heightened stability to deterioration, were investigated. New banknotes of paper for real circulation also were investigated.
     Energy parameters of special purpose paper surface research showed that paper with better immunity to dirt has more low-energy surface comparing to less immunity to dirt. Polarity of paper for real circulation surface 11 % higher than Arjo Wiggins paper. Meanwhile Arjo Wiggins paper surface tension almost 46 % higher, substantially because of polar component. Watering angle and steeping in ethylene glycol are also less than of paper for real circulation.
