Giving hydrophobicity and study of properties of cotton fabric

An effect of a hydrophobic composition based on polymers on the hydrophobicity and performance properties of cotton fabrics of various surface structures has been studied. The processing of the fabric was carried out by a plus method. The persistence of the achieved hydrophobic effect was evaluated by the emergence of the first drops of water through the tissue and the wetting angle. High hydrophobicity values were observed in samples treated with an aqueous emulsion of fluorine-containing dispersions. The stability of the water-repellent property is achieved by heat treatment of padded samples at a temperature of 150°C for 2 minutes. The colorimetric method has studied changes in the color characteristics of cotton fabric after hydrophobic finishing.
