Fabrics made with polyester scrim and coated with PVC are the most popular industrial fabrics for architectural applications.
PVC coated fabric is made with a liquid PVC coating on both sides of the scrim. This is done in a knife coating process. The first step is the application of an adhesive coating on the scrim, then the PVC coating is applied as a liquid.
Lastly, in many cases a finish topcoat is applied which provides better resistance against dirt by sealing off the plasticizers inthe PVC, which otherwise migrate to the surface and make it sticky. Some finish coatings also provide additional UV resistance which extends the life of the fabric.
