| Abstract | Modification of chemical fibres with copolymers of 1,1-dihydroperfluoro-heptyl acrylate (PFHA) to decrease their wettability was systematically investigated and some characteristics of this process were established. It was shown that the effectiveness of modification is determined by the method of treating the fibres with the copolymer modifiers, the molecular composition of these copolymers, and the colloid chemical properties of the latexes based on them. Treatment of the fibres with copolymers with functionally active groups capable of reacting with the macromolecule of the fibre-forming polymer and cross-linking on the surface of the fibre is the most effective method of modification. Substitution of incomplete fluorinated alcohols or unfluorinated monomers for the acrylates in the PFHA copolymer reduces their effectiveness in modification. Copolymers of PFHA with hydrophilic monomers capable of being orientedly sorbed by the fibre due to its amphiphilic nature and forming surfaces with low energy are an exception. For effective use of the copolymer modifier, the latexes of these copolymers should have certain colloid chemical properties: the particle charge, adsorption saturation, and aggregate stability should be optimum, which will ensure their stability during preparation, storage, and use. |
