Melting points
I have added the melting point range for the family as found at http://www.machinedesign.com/BDE/materials/bdemat2/bdemat2_29.html to the page. I realise that this is a family of compounds, but people generally think of a single substance called 'Nylon' and as such I would consider it to be useful to have a rough indication of the melting temperatures on this page.

PA 6 and 66 draw
About PA 6.6:

"Since each monomer in this copolymer has the same reactive group on both ends, the direction of the amide bond reverses between each monomer..."

And about PA 6:

"The peptide bond within the caprolactam is broken with the exposed active groups on each side being incorporated into two new bonds as the monomer becomes part of the polymer backbone. In this case, all amide bonds lie in the same direction..."

So, were the chains PA 6 / 66 drawn (http://en.wikipedia.org/wiki/Image:Nylon6_and_Nylon_66.png) correctly? In there, both amide group are in the same direction. I would like to know...

Thanks!

Gloss on one side of thin Nylon fabric, how do they do that?
An unanswered question from 1970. One day in 1970 I noticed that strange gloss on the outside of a thin darkblue Nylon jacket my mother bought for me when I was age 6. Up to this day (2019) there seems to be no answer to that question. How do they do that? (the gloss on one side of thin Nylon fabric, no gloss on the other side).

Nylon 510 section not really about Nylon 510
The section Nylon 510 was tagged a few days ago as not citing any sources. This is true, but there is another problem as well. Of 13 sentences, only the first is really about Nylon 510, and the third mentions PA 510 as one item in a list. The rest of the section is really a collection of miscellaneous points about other polyamides which should be moved elsewhere in the article. So some serious re-organization is needed here, especially for the material in this section. Dirac66 (talk) 01:17, 2 March 2020 (UTC)

Petroleum product
One could read the entire lead, and much of the article, before discovering that nylon is made from petroleum. There are innumerable sources for this; here's one. The word oil is mentioned first 2,300 words into the article (but not described as its manufacturing origin), crude oil 4,700 words in, and petroleum is mentioned not once in the entire article. Where nylon comes from, is one of the five-W questions to be answered by any encyclopedic or journalistic article about nylon, which means high up in the lead, probably in the WP:LEADSENTENCE, and prominently in the body of the article. I don't plan to make changes to this article as I'm busy elsewhere, but hopefully some regulars or others here will attend to this. Thanks, Mathglot (talk) 22:11, 9 November 2020 (UTC)


 * The first sentence says "Nylon is a synthetic polymer", and the linked article on synthetic polymers starts off with "Synthetic polymers are derived from petroleum oil". Seems that none of our other articles on specific thermoplastics mention petroleum in the intro. – Thjarkur (talk) 23:06, 30 December 2020 (UTC)


 * Thanks for pointing this out. In the linked article, I have now changed "derived from petroleum oil" to "often derived from petroleum oil", since there are many exceptions. Dirac66 (talk) 01:58, 31 December 2020 (UTC)
