PROCESS FOR POLYMER COATING PRODUCTION ON THE COTTON CLOTH SURFACE Russian patent published in 2017 - IPC D06M15/273 D06M13/188 D06M14/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for polymeric coatings obtaining on cotton cloth surface coatings to provide hydrophobic properties, which an be used as protective, water- and dirt-repellent coatings. The method comprises cloth treatment by immersion to the solution grafted onto the cloth surface, followed by heat treatment at 140°C. At that, the cotton cloth is kept in polyglycidylmethacrylate solution in methylethylketone. The resulting polymer coating is modified with a fatty acid, selected from stearic acid, lauric acid or palmitic acid, by keeping the cotton cloth in an acid solution with a concentration of 10-50 mmol l in isopropyl alcohol and subsequent heat treatment at 140°C for 20 minutes.

EFFECT: increased hydrophobicity of cotton cloth.
