Abstract The effects of various cellulose treatments on the hydrophobic properties and sorption behavior with respect to liquid water uptake vapor were examined within study. Different agents based silicon compounds applied improve cellulose-based sheets. 1H,1H,2H,2H perfluorooctyltriethoxysilane treatment increased hydrophobicity significantly, while N-octyltriethoxysilane inorganic sodium silicate solution only slightly affected properties. Silicone-cellulose interaction varied, influencing fiber saturation moisture content material. swelling differences between untreated treated and, consequently, uncovering new active sites during a process increase in bound confirmed by T2 relaxation times analysis. GDW model estimated maximum but lacked activation dynamics. blocking phenomenon together silicone improved had different mechanisms for agents. additionally cross-linked silane structure restricted swelling.
