General scope of article
This article should be about the different poly-esters, short intro about what ester is, history of the term, examples of different particular polyesters... "using polyester yarn made from PET" ... "liquid polyester resin, the most common resin used to make fiberglass fiber reinforced plastic" ... etc. A very detailed disambig article. The details of the particular products, like history, terminology, melting point, etc belong in the particular articles. Is vinyl ester resin technically a polyester? What about polycarbonate (esterification but not make with alcohol)?188.8.131.52 (talk) 21:11, 11 November 2014 (UTC)
What do the different ratings mean?
Could someone please explain what the different ratings, such as "600D ripstop" or "1200D" for polyester fabric mean? 600D 1200D "D" represents Denier,(indirect yarn count ) which denotes the thickness of the yarn. 600D implies -- 9 meters <-[Should be 9 kilometers.] of yarn weigh 600 grams 1200D implies- 9 meters of yarn weigh 1200 grams —Preceding unsigned comment added by 184.108.40.206 (talk) 14:56, 4 June 2008 (UTC)
This article reads like some ad written to support the polymer industry. No word about the amount of Phtalates needed to produce elastic polymers nor about adverse effects of wearing/using Polymers for skin and general health. Whoever wrote this article and edited it is a disgrace to journalism! — Preceding unsigned comment added by 220.127.116.11 (talk) 13:12, 11 April 2012 (UTC)
What about Health Effects?
Almost every other article on Wikipedia involving chemicals and synthetics makes at least some mention of health risks associated with production and consumption of materials from said chemicals. I find no mention of formaldehyde gas or any other toxic or carcinogenic byproduct of polyester. It seems like an entire section is missing from this article. — Preceding unsigned comment added by 18.104.22.168 (talk) 23:52, 10 February 2012 (UTC)
Re: Health Effects
Formaldehyde gas and other toxic chemicals never leave the plant.
Polyester clothing doesn't interact with your body; plastic atoms don't enter anymore your skin by simple contact than cotton or wool atoms.
Phtalates and other unfixed agents may be more of a problem though, with several studies indicating adverse consequences on health, but you will never get a definitive answer to your questioning.
- The long-term effects of a substance or activity on human health are extremely difficult to measure accurately, whether it concerns phtalates, red wine, animal meat, or cocaine. The first reason is that you'd need identical test subjects with only the factor changing, and humans never are -- or stay -- identical, the second reason is that you'd need to follow these test subjects for decades.
- While doing that is possible, it would require enormous amounts of money and human efforts (twins in a closed and controlled environment studied for 60 years), and at this time no organization or corporation is interested.
There isn't a problem simply with phtalates, there is a problem with all modern technology, whose health effects are globally unknown. — Preceding unsigned comment added by 22.214.171.124 (talk) 03:19, 12 May 2012 (UTC)
- Well, wool can cause nasty rashes too, so that's not an argument against the fact that polyester can cause nasty rashes. 126.96.36.199 (talk) 23:11, 9 September 2015 (UTC)
Where is it produced?
This says nothing about where it is produced. Please get more information.Eddy Dude 04:30, 30 September 2007 (UTC)
I'm curious to know if polyester products will melt into my skin during a fire, or protect me from flames like wool would. —Preceding unsigned comment added by 188.8.131.52 (talk) 10:34, 8 January 2008 (UTC)
- Polyester clothing would melt to your skin, like plastic. In general, natural fibres (like cotton, linen, wool etc) tend to be more fire-resistant than synthetic ones (like polyester, nylon, rayon, etc), except sometimes (like kevlar, neoprene etc). Fire performers wear 100% cotton. --184.108.40.206 (talk) 00:14, 4 October 2008 (UTC)
- Welders do not wear ordinary cotton like flannel, it is always catching on fire. And they do not wear polyester; it doesn't catch on fire from metal droplets, but simply melts (in place, not to the skin) without slowing the droplets down and lets the droplets keep traveling where they do burn the skin! They wear wool or treated flame-resistant fabrics.220.127.116.11 (talk) 20:06, 11 November 2014 (UTC)

- NGC/Escape from technology, mentioned reinforced glasfibre(?) polyester. That would not catch fire despite being subjected to directed flame for substantial time. It's used in oil platform escape boats. Electron9 (talk) 01:57, 8 May 2008 (UTC)
- I wanna no what polyester is made from. what part it is made from if it has a latin name or not and what its strengths are! but this site isnt telling me! from tyler paige smith —Preceding unsigned comment added by 18.104.22.168 (talk • contribs) 11:10, 15 March 2008
At what temperature does polyester melt? This was not given in the disciption of its properties. HRH 10/30/08
What is Siliconized Polyester? I am seeing a number of products using this but cannot find any information on it. TL 05/01/10
Blatant copying and pasting
A large portion of this article save for the introductory paragraph appears to be a straight copy and paste. Also references 4 and 5 are not specific cites but just websites. Meowist (talk) 05:32, 14 September 2008 (UTC)
At what temperature does polyester melt?
To a layman such as myself, most of this article makes no sense. I can't get any information out of it if I don't understand it. It needs to be rewritten in simpler terms. I would change it myself, but I don't really know much about polyester. —Preceding unsigned comment added by 22.214.171.124 (talk) 21:00, 1 January 2009 (UTC)
Response: That's common to most Wikipedia articles touching on an even slightly technical subject. What I usually do is just read the first section and then skip it at the point where it starts getting so technical that only an expert could understand it. —Preceding unsigned comment added by TimMagic (talk • contribs) 18:38, 8 January 2009 (UTC)
According to Pavia's Introduction to Organic Laboratory Techniques, a cross-linked polyester is also called a "Glyptal resin". (page 407-8). For some reason, "Glyptal" redirects to a list of characters from an Asimov novel. I'm changing it to redirect to this article. Fuzzform (talk) 22:53, 25 January 2009 (UTC)
- Glyptal was a trade name for an insulating varnish from General Electric. In general, vegtable-oil varnishes work by oxidising, but some synthetics like urethane react with moisture vapor. Need article on Glyptal.126.96.36.199 (talk) 20:15, 11 November 2014 (UTC)
History (Development and Use) of polyester
There seems to be little information on the actual invention/creation (by person or institution) - or ongoing manufacture and development of the material up until its latest version(s) - giving any reasonable form of historical time-line. SteveECrane (talk) 10:48, 14 March 2011 (UTC)
I referenced this entry to find out about the development and history of use of polyesters (and specifically synthetic polyesters) but found little info here - perhaps this article could be expanded to cover these also? Zenira (talk) 05:44, 23 July 2009 (UTC)
- Oi, you lot! WHEN was the stuff introduced? Who invented it? Doesn't anyone know? I see no HISTORY here! —Preceding unsigned comment added by 188.8.131.52 (talk) 13:27, 23 August 2009 (UTC)
Glyptal redirects here, but what is it? Webster says
Chemical Industry Resin formed by condensation of polyhydric alcohols with polybasic acids. They usually contain fatty acids as well(oil-modified alkyds). Source: European Union.
- I'm not sure why it redirects here. I know that it is a common brandname for an engine block coating commonly applied to the internal surfaces of the oil cavity (at least in the US). Wizard191 (talk) 14:20, 5 April 2010 (UTC)
Btw., i found the name in rp Feynmans book "surely you´re jokin", where he says it was sticking all over the place (of a cyclotron) from people using it to fix the vacuum. --Maxus96 (talk) 20:38, 5 April 2010 (UTC)
- There is something two points up on this page. Crosslinked polyester resin sounds sensible, if people use it to glue up their vacuum apperatures. Probably someone should just change the redirect to a short disambiguation. --Maxus96 (talk) 02:45, 6 April 2010 (UTC)
== Fabric == I bought a soft furry blanket and it is polyester and it is made in china and I have seen the videos of what they do to animals, and I was not even thinking and bought them, are they moreless made of animals they killed. I know this is a harsh subject but I am a vegetarian and I don't kill anything and I feel very strong about this subject, I really cant believe I did this If this is true. Elizabeth Motis
Needs many more references
It needs many more references, 10 claims and only 2 references. I could remove all the unreferenced text, but that will usually give me a warning, shame I can't be bold.--UserWOLfan112 Talk 16:51, 23 March 2012 (UTC)
A 'History' section would be nice
Who & When & Where Invented
Maybe do an US patents search, such as # 2,903,021 Fourdriner Cloth Huyck & Sons, NY NY Dec 23, 1955. Or # 2,448,032 Textile Fabric (1944). — Preceding unsigned comment added by 184.108.40.206 (talk) 17:29, 19 September 2014 (UTC)
History section desperately needed
I see this has been frequently requested. It's essential. Please could someone knowledgeable provide a history section? When was it developed. By whom> Where? How? etc etc — Preceding unsigned comment added by 220.127.116.11 (talk) 11:02, 20 October 2015 (UTC)
