Surface Energy of Viscose Fibers Modified by a Fluoropolymer in Supercritical Carbon Dioxide

The effectiveness of rendering fibrous materials non-wettable by liquids of various chemical natures using supercritical CO 2 fluidics technology was analyzed. Poly-2-perfluoropentoxytetrafluoropropylacrylate was selected as the modifying compound. The effectiveness was evaluated by determining the surface free energy of the treated material and its antiadhesive properties (water- and oil-repellent). Also, the effect of this modification method on the strength characteristics of threads was examined.
