Modification of textile fibres with nanolayers of fluorine-containing interpolymer complexes

A method of modifying textile fibres based on application by layers of an anchor polymer and a fluorine containing SF capable of forming a nanosize surface interpolymer complex that gives the fibres assigned properties is proposed. Formation of the interpolymer complexes of fluorine-containing SF with cationic water-soluble polymers was investigated. It was found that particles from 52 to 59 nm in size are formed as a result of the intermolecular interaction, and a modifying nanosize layer forms when they are deposited on the fibres and treated with heat. Surface modification is not inferior in quality to modification using polymer nanodispersions — synthetic fluorine-containing latexes. The modifying effect of the interpolymer complexes is almost independent of the nature of the textile materials.
