Wettability is an essential property originating from liquid-solid contact and involved in various processes and applications. For fabric materials, the wettability plays important role that it can even determine the fabric s usefulness and comfort feature. This book introduces three functional fabrics, such as superhydrophobic fabric, directional water-transfer fabric, and electrically conductive superhydrophobic fabric, which are prepared by tuning the fabric wettability using wet-chemical coating technologies. It covers details about the preparation of coating materials, coating processes, and detailed characterizations of the coatings and their effects on fabric properties.
