There are several mechanical systems available to coat on textiles. Choosing the correct one depends on the nature of the substrate, the polymer, the amount to be coated and, of course, the final application field. Finishing textiles with a coating technique can change the appearance, the surface, and the technical specification of the textile. Textiles for home furniture, for garments, and for technical applications are different, need different treatments, have different requirements and need the appropriate coating technologies. In the market, there are hundreds of polymers available but almost all of them can be coated with knife or roll coating technologies. The industrial lines for coating on textiles are normally called «direct coating lines».
