Polyester accounts for 54% of clothing products—it’s popularity stems from how easy and cheap manufacturers can create it. What does that process look like & how is it so toxic for us & the world?
HOW POLYESTER IS MADE:
- Create a monomer: PETROLEUM, YES PETROLEUM is extracted & then broken down into ingredients. Ethylene and p-xylene are extracted from petroleum, which are the two monomers needed for making polyester.
- Monomer to polymer: The monomers are then mixed with dimethyl terephthalate, creating the polymer polyethylene terephthalate (PET), which is the plastic in SODA/WATER BOTTLES.
- Extrude: Once formed, PET is extruded so it can dry and harden
- Melt and spin the pellets: Once cut up into small pellets, the PET pellets are then melted again, and the molten PET is extruded through spinnerets, which are tiny holes, to form thread. After these threads cool, they harden into polyester fibers.
Polyester yarn: The fibers are twisted into polyester yarn and are ready to knit into fabric. The fibers can be cut or further altered with various chemicals to achieve specific results.
There's no way any reasonable person would think that wearing a heated and reheated plastic is in any way healthy? The main reasons polyester is so widely adopted:
- Very cheap to produce
- Wrinkle & stain-resistant
HOW IT POLLUTES THE WORLD:In 2015, polyester produced for clothing emitted 282 billion kg of CO2 – nearly three times more than for cotton.
HOW IT IS TOXIC FOR US:
- Perfluorochemicals (PFCs) - makes polyester stain-resistant. Causes reproductive issues & liver damage
