Talk:Nylon 6

The number always gives the length of the carbon chain. If there are two numbers it is created by polycondensation of a diacid and a diamin Nylon 6,6. With one number it is created by ring opening polymerisation from a lactame. Stone 09:57, 29 January 2006 (UTC)

Ring-opening vs. Water Catalysis
I'm not an expert on this, but I've heard that, in addition to ring-opening spontaneously at high temperatures, caprolactam can polymerize to nylon-6 in a water-catalyzed reaction. I imagine water attacks the carbonyl somehow but I can't find any details. If there is an alternate synthesis path it's probably worth mention. — Preceding unsigned comment added by 131.215.220.166 (talk) 18:41, 10 March 2013 (UTC)

Nylon 6 vs Nylon 6,6
The two companies agreed to a full patent exchange and a seperation of the sales areas in 1939 because DuPont and IG Farben saw that the difference of the two products was marginal and the competition would only lower the income from the product. This should also be in the text somewhere. Also that both polymeres where sold as Nylon. In 1952 the name Perlon was created to make a difference.

Nylon-6 Promotional Group
The Nylon-6 Promotional group (NPG-6) is a group to "Enhance the opportunities in Nylon-6 related industries by means of more collaboration and communication.” The website: www.NPG-6.com has a lot of information about the members, but also about Nylon-6 applications/properties/production processes. It would be helpfull if the NPG-6 link would be present on the Nylon-6 and Caprolactam page. —Preceding unsigned comment added by Mcsys (talk • contribs)
 * I am removing the link to the homepage of npg-6, I could concur if the page is linking to a page on npg-6 which tells more about nylon-6, now non-specialists have to search for the information. I do not know if this link concurs with wp:el, I would like to hear some opinions on this page.  --Dirk Beetstra T  C 18:40, 18 October 2006 (UTC)

The Nylon-6 Promotional Group (NPG-6) is an international group of companies that are active in the Nylon-6 industry, ranging from raw materials to fibres, textiles, engineering plastics, film and dedicated equipment. Nylon-6 is a dynamic, exciting and incredibly versatile material. This high performance polymer is unrivalled in its number of applications, including textiles, carpets, industrial fibres, engineering plastics and film. NPG-6 provides information about the value and performance of Nylon-6 in its many uses. The activities of NPG-6:
 * Promotion of Nylon-6
 * Provide a global networking platform
 * Conduct market surveys & application studies
 * Stimulate business chain cooperation and developments
 * Increase knowledge

That sums it up, I really think that the NPG-6 site has added value for the visitors of the wikipedia-Nylon-6 page. Could you please put the link back? —Preceding unsigned comment added by Mcsys (talk • contribs)
 * I have read your request, I will wait for some more responses. My opinion: an external link to the page about nylon 6 on nylon-6 and caprolactam could be useful.  Not to the homepage of NPG-6.  (Copied from the talk page of user:Mcsys).  --Dirk Beetstra T  C 13:41, 2 November 2006 (UTC)


 * I agree, putting links to NPG-6 seems more like advertising for it. Xcentaur 18:03, 4 November 2006 (UTC)

The applications of Nylon 6
It would be interesting to mention more about the use of Nylon 6 in: Tire Cord, Textile, Engineering plastics, Film and Carpet.

On the following site: http://www.npg-6.com/internet/en/html/algemeen/publications/publicationsandpresentations.pshe#I466WN17A162HU21252H There are Nylon 6 application sheets, explaining the Nylon 6 use.

Do you guys think it will contribute to wikipedia, to add the sheets or its contents?

thanks, --Mcsys 09:09, 13 February 2007 (UTC)

Content shifted here
In the 1990s, BASF, a German chemical company, began experimenting with Nylon 6 as part of their '6ix Again' nylon recycling program. The end result was Savant@, a carpet material made of Nylon 6 fiber that can be reused indefinitely. The Nylon 6 in Savant@ can be depolymerized and rematerialized into Savant@ with virtually no loss. The Nylon 6 is referred to in sustainable design as a technical nutrient where materials (nutrients) from the old fabric form the basis of the next generation of material in what is a closed loop. Unlike most recycled materials technical nutrients are not downcycled into their next application. In this case, the end product Savant@ is of similar or greater value than the original Nylon 6.

Absorbing water.
It says Nylon 6 absorbs "2.4 percent of water". Someone should specify whether this is by weight, volume, or ocean size... 184.57.194.188 (talk) 16:15, 18 November 2013 (UTC)

Wrong use of the wording Nylon
It is frustrating that also here in the english version of Wikipedia the entry on Nylon is wrong. The differentiation is between Polaymide 6 (PA6) and Polyamide 6,6 (PA6,6). Only Polyamide 6,6 is Nylon while Polyamide 6 is Perlon. I know that commonly people name all Polyamides as Nylon which is not correct but something like Wikipedia should be correct. — Preceding unsigned comment added by 80.156.9.73 (talk) 11:58, 9 August 2016 (UTC)

Unknown units
Its tenacity is between 6 and 8.5 gm/den with a density of 1.14 gm/cc. What units are "gm/den" and "gm/cc"? Hateras (talk) 10:57, 29 May 2019 (UTC)
