Vinyl-coated polyester is a frequently used material for flexible fabric structures. It consists of a polyester fabric, an adhesive or adhesive agent, and an outer PVC coating. The mesh supports the coating (which is initially applied in liquid form) and provides the tensile strength, elongation, tear strength and dimensional stability of the resulting fabric. Depending on its formula, PVC lining makes the material impermeable and resistant to dirt, mold, oil, salt, chemicals and UV rays and gives the material a greater strength and durability. It can be sewn or heat-sealed by RF (radiofrequency) welding or hot air welding.
The tensile strength of the base fabric is determined by the size (denier) and the strength of the threads and the number of threads per linear distance. The higher the yarn and more yarns per inch, the greater the tensile strength of the finished product.
The adhesive agent acts as a chemical bond between the polyester fibers and the outer coating and prevents fibers from absorbing or absorbing water in the fabric. This prevents damage caused by the water absorbed during a freeze thaw cycle.
The PVC coating (Organisol vinyl or Plastisol) contains chemicals to achieve the desired color, water, mildew resistance and flame retardant. The fabric can also be fabricated with light transmission levels ranging from very transparent to completely opaque. After the coating has been applied to the fabric, the fabric is placed through a heating chamber which dries the liquid coating.
