Comparative Effectiveness of Use of Fluorine-Containing Polymer Modifiers to Reduce the Wettability of Viscose Fibres.

The comparative effectiveness of using polyfluoroalkyl acrylates, which have the structure of a fluoroalkyl radical, in reducing the wettability of viscose fibres was investigated. It was shown that incorporation of an oxygen atom in the fluoroalkyl chain decreases the efficiency of modification with all other conditions being equal. An important increase in the level of unwettability can be attained by regulating the colloid chemical indexes of polyfluoroalkyl acrylate latexes, their particle charge values in particular.
