ABSTRACT:
Competitive absorption processes, i.e. condensation, of water and essential oils (EO) are predominantly controlled by
extent of condensation of diffusing water and EO molecules with marginal
influence of porose ligno-cellulosic matter and a sort of EO. With increase of
absorption the diffusion is depressed and vice versa. Diffusion of water
molecules through porose system is usually slower in comparison with other
molecules. It was discovered that a presence of EO decreases paper web humidity
with increasing influence in environment with high relative air humidity.
Likely, fast diffusing EO molecules decrease the ability of water molecules
condensed in all accessible pores particularly in the non-penetrable pores.
