I always assumed that the novelty yarns I knit with were acrylic, but I checked the labels and instead it says "100% polyester" "100% nylon."

so are these synthetic or natural :?? I figure they've got to be synthetic to be so cheap.

When people say 'acrylic' I always read it to mean 'synthetic' not specifically acrylic in composition.

Polyester and Nylon are both synthetic. The term synthetic means "man made".
When Nylon was invented during WW2 it was quite miraculous and became very famous for stockings. During the war silk stockings were in short supply for women and nylon stockings were a great substitute. The first doll in the 50's with washable hair was the Toni Doll and her hair was made of Nylon.

Polyester is a petroleum based product like plastic. It is long wearing and easy care- thus it's popularity (and over use) in the 70's. Because it is petroleum based the price can go up when oil prices go up. I know that is the case with carpeting since it contains a lot of poyester.

Acrylic is another synthetic fiber http://en.wikipedia.org/wiki/Acrylic_fiber.

All this makes chemistry class seem a bit more relevant to fashion doesn't it?
