Surface Modification Using Nano technology to Impart Super Hydrophobicity
Cotton fabrics are generally hydrophilic in nature, however, some applications like upholstery fabric, uniforms, bags etc. demand that they be imparted with hydrophobicity.
Nano Zinc Oxide nanoparticle was used to modify the surface properties of cotton fabric to impart super hydrophobic property, UV-protection and anti-bacterial property.
The treated fabric had higher wetting time of more than 60 seconds, and excellent UPF rating of 50+ even after eight wash cycles.
