Cotton, a crucial raw material for the textile industry has the worldwide popularity for its use. Cotton is the fabric for every home due to its comfortability than other fibers product. It is composed basically of cellulosic and non-cellulosic substances, a secondary wall and a tertiary wall. The cell wall polymers are very easy to form a crystalline composite due to their numerous hydroxyl groups, which help cotton changes dimensions with changing outside force inducing crease to the material. The most important factor in the textile fabric is moisture transport. Water absorption is strictly interconnected to moisture absorption and wettability. Cotton is a very comfortable to wear in all season. The cellulosic hydroxyl group in cotton fiber makes it tremendous water loving adsorbent. So the surface modification is a very important task to improve water repellent properties that rapidly move water away from human body makes the wearer feel more comfortable with keeping him dry. Such extremely water-repellent surfaces are observable in nature, mainly on lotus leaves.It has been investigated that such extremely superhydrophobic behavior of lotus leaves arises due to the presence of hierarchical rough structure, and waxy layer present on leaf surfaces.  Inspired by the lotus leaves phenomenon the textiles are prepared by tailoring the surface morphology using techniques such as adsorption of low molecular compounds(); electrodeposition(); chemical etching();laser treatment(); chemical vapour deposition(); grafting of polymers(); growth of polymeric nanofillers() or carbon nanotubes() or ZnO nanorods() etc. to improve its water-loving character.

            Among known methods, fluorocarbon coatings exhibit undesirably high water contact angle by lowering the surface free energy and make fabric hydrophobic. Small size and high electronegativity of fluorine element make the covalent bond between fluorine and carbon are exceptionally stable. Fluorocarbon based polymers have been demonstrated to have super-hydrophobic properties when hydrogen is replaced by Fluorine elements in the order –CH3
