Coated and laminated fabrics

Coated and laminated fabrics consist of a textile substrate, which may be woven, knitted or non-woven, combined with a thin flexible film of polymer. Substrates for high performance fabrics tend to be based on polyamide/nylon 6, polyamide/nylon 6.6 and polyester because they provide high tear strength, high dimensional stability and resistance to microbiological and chemical attack. Flat multifilament fabrics provide a thin hairless surface and if the fabric is used as the outer layer, it prevents abrasion of the coating and sheds liquids and soil readily. Silicone or fluorocarbon finishes enhance the effect. Texturising of the filament yarn increases adhesion, improves handle and reduces noise and shine.

Coating	Polymer Film
A coated fabric consists of a textile substrate on to which the polymer is applied directly as a viscous liquid. The thickness of the film is controlled by a doctor knife. Note that coating penetrates the fabric	A laminated fabric consists of a textile substrate which is combined with a pre-prepared polymer film or membrane by adhesives, heat or pressure. Note that the polymer film does not penetrate the fabric

The fabric increases the tensile and tear strength of the film or coating, improves the puncture resistance and gives a better handle.
