This work focuses specifically to hydrophobic finishing of clothing textiles, which seeks better way of imparting waterproof and water repellency on the textile substrate without compromising other properties like breathability, air permeability of the clothing apparel. The study compared impregnation and coating hydrophobic finishing by using polyester fabrics of two different yarn count and sett, whereby characteristic properties such as spray test, hydrostatic pressure, air permeability and breathability were determined. Therefore correlation between applied finishing and resulting quality of the textile be simulated. For impregnation, fluorochemical has been utilized. This reagent has an ability to reduce the surface tension of the fabric considerably; hence it repels both water and oily liquids. Fluorochemical also exhibits good chemical and thermal stability. Furthermore, has low reactivity due to their incompatibility with water and oil. For coating, two resins namely: acrylic and acrylic/polyurethane (80:20) were used and therefore their performance being compared for properties mentioned above, whereby Werner Mathis CH-8155 laboratory foulard was utilized to carry out both impregnation and coating using floating knife technique for coating.
