There's also a similar piece that just ran on 60 Minutes: "A Whopping 91% of Plastic Isn't Recycled" by Laura Parker on nationalgeographic.com So, when I open a bottle of Deer Park water, there's a 90% chance that it will end up in the ocean, or in a landfill, despite my going to great lengths to recycle it? Predictions are that by 2050, the oceans will contain more plastic than FISH. NO THANK YOU. I've got to change my ways.
Although Herschel's post is from the Yankees' Pinstripes Thread, this applies very much to the Science Forum. I simply do not believe that polyester is more breathable than cotton - I believe the best materials are lighter, repel water better, dry out much more quickly, wick the perspiration to the outside of the clothing (I think this is the key argument for polyester), and are stretchier, but in terms of letting outside air in, I don't care what scientific tests say - unless things have changed substantially in the past ten years or so (and maybe they have), no polyester can breathe like cotton. I'm a sweater - always have been - and I would go through four and five shirts a *set* in tennis sometimes, always cotton. There's no question that material becomes drenched, and stays drenched, but it also breathes. The high-tech water-repellent polyester tennis apparel I tried out for a couple years stayed drier for *sure*, but they also smelled like plastic, and that was whether they were clean, or not - you could pull them straight from the washer and drier, and they'd smell like plastic. I *hated* them, and I just resolved myself to bringing up to *ten* shirts for a given tennis match, and threw them all in the washing machine afterwards. It's true that once they become saturated, they don't dry out quickly, and maybe this is what "Science" is talking about - polyester keeps you drier: I can buy that. But I can't buy that it "breathes" better than cotton. For casual summer wear (non-athletic), I never, ever buy polyester; only cotton.
