The most common material for flexible fabric constructions is PVC coated Polyester Fabric, which is used in everything from tents to industrial coverings and tarpaulins. It can also be utilized in protective garments for the police and fire departments. These materials are extremely long-lasting, frequently lasting two decades. PVC coated Polyester Fabric is comprised of polyester scrim that has been coated with PVC. Some finish coatings provide increased UV protection, extending the fabric's life, and others create a dirt-repellent surface.
Vinyl-coated polyester is composed of a polyester scrim, a bonding or adhesive agent, and exterior PVC coatings. The polyester scrim supports the coating (applied initially in liquid form) and provides the tensile strength, elongation, tear strength and dimensional stability of the finished fabric. The scrim is made of high-tenacity, continuous-filament yarns, which have high dimensional stability, and can be bent thousands of times without losing any tensile properties. The base fabrics tensile strength is determined by the size (denier) and strength (tenacity) of the yarns and the number of yarns per linear inch or meter. The bigger the yarn and the more yarns per inch, the greater the finished products tensile strength.
