METHOD OF PRODUCING POLYMER COATING ON SURFACE OF COTTON FABRIC Russian patent published in 2016 - IPC D06M14/04 D06M15/353 D06M13/188 

FIELD: textile industry.

SUBSTANCE: invention relates to a method of producing cotton polymer coatings with hydrophobic properties, which can be used as protective, water-, dirt-proof coating. Method of producing polymer coating on surface of cotton fabric includes treatment of fabric by dipping in a solution of fluorine-containing compound, heating and subsequent drying, at that before processing the cotton fabric is sequentially treated in 3 % solution of poly-glycidylmethacrylate in methyl ethyl ketone and 0.1 M in solution of α-bromo-isobuthiryl-bromide in tetrahydrofuran, while processing is performed 1 M in solution of 2,2,2-trifluoro-ethyl methacrylate or 1,1,1,3,3,3-hexafluoro - isopropyl methacrylate in methyl ethyl ketone in argon medium at 80 °C in the presence of catalytic complex consisting of copper (I) bromide and bipyridine ligand.

EFFECT: high hydrophobic properties of cotton fabric.
