Abstract Electrospraying is a method of generating fine droplets through high electrostatic charging. It involves an electrohydrodynamic process for forming fine droplets. These droplets are highly charged that promotes selfdispersion which results in the uniform coating on the substrate. Electrospraying can be successfully utilised as a coating technique to coat textile substrates. Textiles substrate coated with electrosprayed polymer droplets have a large specific surface area, and it facilitates submicron range coating compared to conventional coating methods like roller coating or knife coating. This research study investigates the electrospraying of thermoplastic polyurethane as a coating technique on the textile substrate. The results showed that electrospraying facilitated the submicron size droplets deposition on textile substrates which imparted the waterproof property to the substrate without altering the moisture management and surface properties of the textile substrate.
