I have a smooth brain, but in my line of work "poly" means plastic, and "ester" means petroleum based. Not sure how it relates here but I just said it anyways.
Plastics were invented long before this research was done. The 3 studies cited here were published in 1992, 1993, and 2008 for reference. Polyester was invented in 1941 and widely marketed by DuPont starting in the 1950s.
If you look at textile companies today and ask them why they choose to use it, or Spandex, or Lycra, or nylon, or any of the others, they'll describe the particular properties of the fibers that make their products better. If you are making yoga pants for example (Lululemon got into trouble with this ~10 years ago), you need something which is stretchy, but which does not thin when stretched. A few years after coming to widespread popularity, Lulu switched to a Chinese manufacturer who got clever about cutting costs and changed the fiber mix. Lulu ended up buying and reselling yoga pants that when women went into "down dog" or "dragonfly" (straddle) or certain other positions in class, the fabric in the crotch made your undergarments (or lack thereof) visible. Lawsuits were filed. Outrage was swift. Lulu switched that shit in a hurry and refunded recent purchases to make it right with their customers. They use what they use so the products looks good, feels good, washes clean, doesn't smell, performs through intended use and wear and tear, etc. They're trying to sell products we want to buy and wear.
I guarantee you practically no one knows about this fertility issue unless you're a GYN or GU specialist or you've been a patient seeking fertility treatments to try and conceive.
Poly means many. Ester refers to the specific chemical bond. What makes it a plastic is the specific monomers, the individual parts that get bonded together to make the chain.
Look up, if you're curious, the 7 most common plastics in the US, the ones in the numbered recycle symbols. Only 2 of them are actually recyclable. The labeling is deliberately deceptive. The plastic industry did that specifically to give people the impression it was recyclable, even though it wasn't. They told regulators that a universal symbol was necessary and that industry could work out waste disposal processes for plastics as long as they were numbered and identified. True, but deceptive.
Anyway, if you look at the names, you'll see they're all "poly" something. They're all chains of the various alkanes (the chemical name for the base links in that chain).

Polyester is a petroleum product and basically a glorified plastic.
It also has the unique privilege of being far cheaper than wool or cotton. Hence all the large companies adopted it.
Gotta get that extra 5% on the quarterly earnings report. Make the investors happy. Damn the long term consequences

very interesting thank you
Ah shoot. Looks like I’ve had the etymology wrong on this one, somehow.
Thanks for the correction!
