IRUS ENTERPRISES
Nylon
The characteristic features of nylon polyester fabric
Pleats and creases can be heat-set at higher temperatures
More compact molecular structure
Better weathering properties; better sunlight resistance
Softer "Hand"
High melting point (256 °C/492.8 °F)
Superior colorfastness
Excellent abrasion resistance
Variation of luster: nylon has the ability to be very lustrous, semi-lustrous or dull.
Durability: its high tenacity fibers are used for seatbelts, tire cords, ballistic cloth and other uses.
High elongation
Excellent abrasion resistance
Highly resilient (nylon fabrics are heat-set)
Paved the way for easy-care garments
High resistance to insects, fungi, animals, as well as molds, mildew, rot and many chemicals
Used in carpets and nylon stockings
Melts instead of burning
Used in many military applications
Good specific strength
Transparent to infrared light (−12 dB)
Polyester
Vinyl coated polyester is a material frequently used for flexible fabric structures. It is made up of a polyester scrim, a bonding or adhesive agent, and an exterior PVC coating. The scrim 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, the PVC coating makes the material waterproof and resistant to dirt, mildew, oil, salt, chemicals and UV rays and gives the material added strength and durability. It can be sewn or heat sealed by way of RF(Radio Frequency) welding or hot-air welding.
The base fabric's tensile strength is determined by the size (denier) and strength of the yarns and the number of yarns per linear distance. The larger the yarn and the more yarns per inch, the greater the finished product's tensile strength.
The adhesive agent acts as a chemical bond between the polyester fibers and the exterior coating and prevents fibers from wicking, or absorbing water into the scrim. This prevents damage caused by absorbed water during a freeze thaw cycle.
The PVC coating (vinyl Organisol or Plastisol) contains chemicals to achieve the desired color, water, mildew resistance, and flame retardancy. Fabric can also be manufactured with levels of light transmission that range from very transparent to completely opaque. After the coating has been applied to the scrim, the fabric is put through a heating chamber that dries the liquid coating.
