It was shown that solutions of tetrafluoroethylene telomers in acetone form a coating on the surface of fabric which forms a thin fluoropolymer film after heat treatment and gives polyester fabrics a high level of water repellency. Methods of acting on the fibre material that allow additionally increasing the degree of water repellency due to regulation of the thickness and ordering of the fi lm and acting on the microrelief of the fabric were revealed. Preliminary chemical activation of the polyester material and an abrasive effect on its water-repellent coating are proposed for this purpose.
