AB - Electrospray coating is a method of generating fine droplets of polymer through high electrostatic
charging. It involves electrohydrodynamic process for forming fine polymer droplets. These droplets are
highly charged that promotes self-dispersion which results in uniform coating on substrate. Electrospray
coating 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 electrospray coating of thermoplastic polyurethane polymer on 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 textile substrate.
