Answer: A
Dacron is the trade name of polyethylene terephthalate (PET), spelt 'tetraphthalate' in the paper.
PET is the polyester made from ethylene glycol and terephthalic acid. DuPont sold the fibre as Dacron in the United States, and the same polymer is Terylene in Britain. It is the commonest synthetic fibre found in textile evidence.
Nylon 6,6 and nylon 6 are polyamides, not polyesters; nylon 6,6 was DuPont's earlier fibre sold simply as nylon. 'Dimethylene tetraphthalate' is not the polymer of any commercial fibre.
