Polyester is generally considered to have a less natural feeling to it compared to natural fibers. Natural polyesters have been known since around 1830. Polyesters exist in the Cutin of the plant cuticle, although generally it refers to the large family of synthetic fibers. Polyester (PET) is a category of condensation polymers, which contain the ester functional group in their main chain. A Polymetric fiber is a polymer whose chains are stretched out straight (or close to straight) and lined up next to each other, all along the same axis. Polymers arranged in fibers like this can be spun into threads and used as textiles. The first polyester fiber called Terylene was patented in 1941 the second polyester was DuPont’s Dacron. Since then we have developed great uses for polyester, such as the beautiful Midori Promenade ribbon. Midori Promenade ribbon is wired and accented with a bold stripe pattern, perfect for dressing up any decoration, and made with 100% polyester.
