About Polyester fabric:
Polyester fabric is a very care free fabric that is also very cheap to produce. The thread is made from a plastic compound. Polyester is not just cheap to purchase, but also has a quite noticeable different feel when compared to silk or rayon/viscous. The fabric doesn't feel as soft, and feels much stiffer. In addition it wrinkles easily. The only benefit of Polyester is that it is cheap and very stain resistant. Polyester clothe is unhealthy for the skin, as it causes sweat retention, irritation and breakouts, especially if worn during the summer months.
Where does it come from?
Polyester is manufactured from synthesized polymers, a petroleum based chemical. The technical term is polyethylene terephthalate or PET.
A lot of polyester comes from recycled sources notably PET bottles such as coke bottles etc.
Recycling is a great way to reduce land fill however recycled PET is never used for food purposes again for obvious reasons, however we do allow recycled coke bottles to sit against our skin in the form of many garments which brings about a nasty thought of who was sucking on that coke bottle that I am now wearing as underpants?
I have had the fortune or misfortune to have visited large recycling markets in China and to visit PET recyclers manufacturing polyester thread. I must say it was like being in one big rubbish tip and with the putrid smell.
The PET bottles are first granulated
The PET granules are heated and then spun somewhat like how candy floss is made
