This page is north Korean propaganda. The fiber is mainly produced in Japan and China. Modifications of the article are immediately deleted or changed by unknown authors. No reliable source. — Preceding unsigned comment added by 87.139.69.19 (talk) 07:03, 1 June 2011 (UTC)[reply]

Most of this article seems to be taken directly from the NKChosun linked to at the bottom. Simply lifting entire sentences with a bit of rewording is not enough to constitute original work, and this article should probably be rewritten from scratch. Just putting a link to the page at the bottom is insufficient... — Preceding unsigned comment added by Suchire (talk • contribs) 05:20, 19 May 2006‎

Romanization Problems

No matter what the consensus at Wikipedia might be, the hyphenation fad in Romanized Korean names is a strictly southern thing and no North Korean would hyphenate their Romanized name as is done on this page. Likewise, the hodgepodge of upper case and lower case initial letters is a recent southern fad and is not common in North Korea. The Revised Romanization System is a strictly South Korean political invention and is not followed in the North. I suggest that North Korean individuals should have their names Romanized in the North Korean style – not according to South Korean nor Wikipedia trends.— Preceding unsigned comment added by 202.79.62.18 (talk) 10:47, 14 May 2007‎

Need to explain why it isn't water soluable

It looks like it's either to do with cross linking due acetalisation resulting in something just to big to disolve or possibly there is some vulcanisation going on (methods of production seem to involve sodium sulphate baths followed by heating).01:45, 13 January 2011 (UTC)— Preceding unsigned comment added by Geni (talk • contribs)

This article is in poor state. It would be better titled "history of vinylon in the DPRK" Please at least explain the production process and why anthracite and limestone would be used as raw materials. From my brief look at it I cannot verify this is the case or where limestone would enter the process. I came here when someone tried to say "North Korea wear material they made from rocks". This is simply not the case. Researching it briefly the feed stocks mentioned are petroleum and natural gas and polymerization of vinyl acetate. Perhaps a novel vinyl but nothing as earth shattering as "North Korea figured out how to make cloth from rocks." — Preceding unsigned comment added by 2605:A601:A0C3:5500:84BB:6A93:9303:D35C (talk) 07:31, 10 February 2021 (UTC)[reply]

The "rock" is calcium carbonate which is used in calcium carbide production (from calcium carbonate and coal and lots of heat). Next calcium carbide and water react to give acetylene and calcium hydroxide. Which means that the "rock" element is again gone out of the product... the actual important intermediate is acetylene. You could say: vinylon is produced from coal and water, with the help of "rock".

This process was used before the 1950s in western countries, but is no longer economically feasible as of today, since the acetylene follow-up products (acetic acid, vinyl acetate) are produced more cheaply from ethylene (which comes from petroleum cracking). Also, production of calcium carbide requires a lot of energy. Even if acetylene is required in western economies, it is today made from methane rather than from carbide and water.138.246.3.168 (talk) 12:37, 17 September 2022 (UTC)[reply]

Apparently is Sold worldwide by Chinese, including the huge company Alibaba

I was curious what it looks like, so went to images.google.com and searched for the material name.

To my surprise I found that the AliExpress division of the Chinese company Alibaba sells a lot of items, including lots of clothes that contain at least as secondary material, vinylon. I am not adding to the article right now, out of extra caution so people do not think I am promoting AliExpress (I do not have any working/business relationship with them or Alibaba at all) but Alibaba is a huge company, so this is sigificant.

URLS google found include cheap-vinylon-fiber.html and vinylon-fiber_reviews.html (thanks to spammers one cannot give legitimate links for information like these so you'll have to search to find, but it's true,they are sold and even described, on AliExpress) these two links are about the fiber, and reviews, respectively. Sometimes vinylon is even listed as the "main material" Spring-2015-spring-new-star-fashion-portrait-self-cultivation-woolen-send-belt/32300905578.html (Note: a few somewhat "not safe for work" images of other clothing like "free shipping leg wear..." are highlighted on the left side, on the screen for this "woolen belt" item in the third external link). How on earth did I get to this page from list of religions by population size and curiosity about what "juche" means, which I'd never heard of..)

It seems worthwhile to mention that it's sold worldwide by Chinese companies (maybe others too? not sure) the article gives the false impression that only people in DPRK/North Korea, that only they wear it, that only they use it.. Alibaba, they have the largest IPO in history, ever, last year I think it was, they are as big a worldwide player as google, so to give the false impression that the only place it is relevant is N Korea, is misleading to readers...

Alibaba are a middleman. They don't make or stock anything and as a result you can buy almost anything through them. Yes we could do with more coverage of the limited use outside of north korea but finding references isn't easy.©Geni (talk) 23:55, 23 May 2015 (UTC)[reply]

Korea Herald Reference

The second reference is to a Korea Herald link that is dead. I managed to find a new link of the same story, however. Needs to be replaced. http://www.koreaherald.com/view.php?ud=20100818000677 — Preceding unsigned comment added by 118.46.224.219 (talk) 05:01, 5 April 2015 (UTC)[reply]
