Hydrophobic finishing and properties of cotton fabric with different surface structures

Abstract

For this study samples of cotton fabric with different relief weaves were selected to study the effect of polymer-based hydrophobising composition on hydrophobicity and performance properties of monochrome fabric of different surface structure. The processing of the fabric was carried out using the plius method. The fabric samples were treated with hydrophobising compositions based on Tubiguard SCS-F, based on EcoperlActive and hydrophobising emulsion. During the experiment it was observed that the fabric pieces soaked with EcoperlActive based hydrophobiser lost their water resistant properties and therefore could not be used. High values of hydrophobicity were observed in samples with relief surface, treated with hydrophobising emulsion as well as with fluorine dispersion. The stability of water repellency is achieved by heat treatment of plated samples at 150-160°C for 6-7 min. It should be noted that the hygienic and colour characteristics of cotton samples are not significantly affected by treatment with all three hydrophobic compositions. The results of the research contribute to the expansion of the range of fabrics with hydrophobic property for household and technical purposes by regulating the composition of hydrophobising composition and the mode of treatment, as well as the choice of fabrics with different surface structure.
