The PET or Polyethylene terephthalate is a polyester of the class of polymers, which is obtained by polymerizing the monomer obtained by the process of etherification between terephthalic acid and ethylene glycol. By virtue of its properties, it is widely used for the production of food containers, in particular the bottles of water. This material is a 100% reusable and recently it has been transformed also in textile fiber.
The PET for clothing is the most breathable fiber between the no-natural ones and it offers an high resistance to abrasion, to creases and to heat, a high modulus of elasticity and a minimum regain of humidity, as well as a good resistance to chemical and physical agents. All of these features give to the fabric crease resistance, wear resistance, dimensional stability and an easy recovery of the creasing even after washing avoiding the ironing. It does not absorb the humidity with the consequent resistance to dirt. It tends to burn with flame retardant and it is therefore in accordance with law 81.
Pastelli uses it in Crepe fabric in a range of 5 colours and the products proposed are optimal for comfort but above all for the low price that it becomes extremely beneficial considering the almost indestructibility of this fiber.
