Polyester (polyethylene terephthalate) is derived from a chemical reaction involving petroleum, air, and water. This artificial fiber is comprised of purified terephthalic acid (PTA) and monotheluene glycol (MEG). Polyester is thermoplastic, meaning it can be melted and reformed. When making polyester, chemists melt polyester pellets and force them through small holes (spinnerets). On the exit side of the spinnerets, the continuous filaments of what we know as polyester fibers solidify. The size and shape of the hole dictate the shape and diameter of the fibers. The fibers are solid polymer; there are no void spaces inside the fibers. These continuous filaments—called “tow”—can be cut to any length (there is no length distribution, all fibers are manufactured to be perfectly homogeneous) to produce staple fibers for use in textiles and nonwovens, or they can be left as a continuous monofilament, which resembles fishing line.

So let’s look at the bigger picture. How can the practice of using recycled polyester instead of virgin polyester make the world a better place? The production process of recycled polyester does not rely on oil as a raw material. If the practice of recycling polyester was widely adopted, we would be able to ultimately decrease our reliance on petroleum and thus discourage its extraction from the Earth.

Firstly, raw white semi-dull recycled polyester FDY yarn has a natural appearance that resembles cotton. This makes it an ideal material for creating eco-friendly clothing and other textile products.

Recycled PET yarn is extracted from discarded mineral water bottles and cola bottles, and waste utilization conforms to the concept of sustainable development, which is conducive to reducing waste generation and better protecting the environment.

After the first stage of polymer production in the melt phase, the product stream divides into two different application areas which are mainly textile applications and packaging applications. In the following table, the main applications of textile and packaging of polyester are listed.

About 49 percent of the world’s clothing is made of polyester and forecasts show this to nearly double by 2030. Athleisure trend has led a growing number of consumers to be interested in more flexible, more resistant garments. But polyester is not a sustainable textile option, as it is made from polyethylene terephthalate (PET), the most common type of plastic in the world. In short, the majority of our clothes come from crude oil.
