Coating covers a range of techniques that offer one of the most important means of conferring additional and novel properties to technical textiles. It is important to realise that the various chemicals and formulations used in industry are very varied and change rapidly over time, and the applicability to the requirements of the end products should be researched thoroughly. Theoretical analysis of lubrication is used to deals with the hydrodynamic behavior of thin films showing the relationship between viscoelasticy and process parameters. Blade coating techniques are the most used to apply a rubber solution either onto or into the structure of a textile and are going to be detailed explained.
