I believe that Dacron is actually PET. At least that's what I read at
Wikipedia.


Dacron was originally PET fiber made by DuPont. It was their registered
trade name, but.is now owned by Invista. When Eastman Chemical Company was
still part of Kodak and still manufactured PET fibers, its trade name was
Kodel. Polyester fibers are made by a number of companies, each with their
own tradename. When referenced as rope, polyethylene terephthalate is
usually implied. However, other thermo-softening polyesters, such as
polybutylene terephthalate end polyethylene nalhthalate, are available.
Thermo-setting polyester resins, too, are found. These are commonly used
in fiberglass boats and some printed circuit boards although most printed
circuits use epoxy resins.

Quoting from the Invista website(www.invista.com):
"INVISTA is independently managed but wholly owned by a subsidiary of Koch
Industries, Inc. On April 30, 2004, subsidiaries of Koch Industries, Inc.
acquired INVISTA from E. I. du Pont de Nemours and Company. INVISTA,
formerly DuPont Textiles and Interiors (DTI), was merged with KoSa, a
producer of commodity and specialty polyester fibers, polymers and
intermediates. KoSa had been a Koch affiliate since 1998."
