Textiles are made impermeable to fluids by two processes, coating and laminating. Lamination consists of bonding pre-prepared polymer film or membrane with one or more textile substrates using adhesives, heat, or pressure. Coating is the process of applying a viscous liquid (fluid) or formulated compound on a textile substrate. .In this paper we have gone through several methods of production used to manufacture a wide range of coated or laminated fabrics. Broadly, they are knife coating, lick roll coating, transfer, rotary, Zimmer, melt coating, and flame lamination & hot melt lamination. A review is made on Coated and laminated textiles applications in Defence, transportation, healthcare, space, environmental pollution control, sports, architecture, and many other diverse end-product uses.
There are two definitions of a 'coated fabric'. The first one is, 'A material composed of two or more layers, at least one of which is a substantially continuous polymeric layer and at least one of which is a textile fabric. The layers are bonded closely together by means of an added adhesive or by the adhesive properties'. The second definition is, 'A textile fabric on which there has been formed in situ, on one or both surfaces, a layer or layers of adherent coating material'.
