Talk: Nylon

From open-encyclopedia.com - the free encyclopedia.

I removed this paragraph:

The word nylon is no longer a trademark as it was deemed to have become a generic term. In a historic lawsuit competitors claimed that Nylon was such a household word that it could no longer be considered a Registered Trademark. As a result, Nylon is now a word in the English language.

Here are references stating that "nylon" was never trademarked, including Dupont itself:

See genericized trademark for a list of former trademarks. Samw 00:43, 5 Oct 2003 (UTC)

Correction? - about - ' inorganic ingredients: coal, water and air'

In the entry for nylon second paragraph, second sentence reads:

It was the first synthetic fibre to be made entirely from inorganic ingredients: coal, water and air.

My question is coal really an 'inorganic ingredient'? So should be be corrected if it isn't a true statement?
