What in the World - Why polyester is in its flop era

Download Why polyester is in its flop era

Have a look at the label in the clothes you’re wearing today. Chances are, you’re wearing some polyester. It’s the most- produced synthetic fibre on the planet and it’s having a bit of a moment on socials. In a bad way…people are giving it up and swapping for more natural fibres.

You might’ve seen claims that polyester is linked to diseases like cancer and can cause fertility issues. But how worried should we be? Professor Mohamed Abdallah from the University of Birmingham breaks it down for us and Chelsea Coates from the What in the World team explains how we can make better clothing choices.
