One of the wonder-fabrics of the Fifties, Dacron was the trade name of a particular polyester sold by Du Pont Chemical – the first from that company and the second overall (after Terylene). Its actual chemical name is Polyethylene terephthalate. It was first sold in New York, where it was used to make a variety of garments, most prominently men’s suits. Although a fashion sensation at the time, it has dropped out of favour since the technophiliac Fifties, and is no longer used as much in clothing.
Modern applications for Dacron include ropes (especially for nautical use) and artificial organs, especially hearts – both applications where Dacron’s lack of biodegradability is desirable.
