Talk:DREF friction spinning

[Untitled]
Hi JIP, I was wondering if I could have a read of the deleted page "Dref Friction Spinning". I do apologise in advance if the format of my request is incorrect as I have no experience in writing in to Wikipedia. Thank you.. 218.111.28.65 (talk) 06:17, 3 August 2010 (UTC)

Multiple issues
I have started on separating the wheat from the chaff. But I am doing it slowly as I feel we do need to understand what the system is before we do anything too drastic! Talk to me if you have any opinions- quatschen mit mir! ClemRutter (talk) 14:41, 11 August 2016 (UTC)

Page rename proposal
This page should be renamed to use a sentence-case title. However, I am unsure whether the new title should be "DREF friction spinning", "Dref friction spinning", or "Friction spinning", although I'm leaning towards the latter. I'm not well-versed in the topic space, but a cursory review of the article and online books/journal publications suggests that the technology is "friction spinning", and "DREF" is the licensed name of the first company/machine family for performing friction spinning.

To further confuse matters, I also found a reference to "open-end friction spinning" or "OE friction spinning", as opposed to "OE ring spinning", and the reference refers to "the commercial process known as Dref-2" as a type of open-end friction spinning. So, friction spinning is a type of open-end spinning?

To further back this up, I found a reference to friction spinning that describes it thus: "This process is included in the open-end group because the fiber strand (draw frame sliver) must be opened completely into individual fibers and then reassembled to a new strand (yarn). The formation of a new strand is carried out by using suction to bring the individual fibers into engagement with the rotating open end of the yarn, e.g. by perforated drums with an internal vacuum." The reference goes on to describe different types of friction-spinning systems, distinguished according to: feed, opening assembly, separation of collecting and twisting functions, number of friction surfaces, and type of friction assembly; some but not all of these are assigned industry examples (ex: "Dref-2000", "Dref-1"). Additionally, the reference names a non-Dref type of friction spinning machine: "The fibers can move to the collecting device in free flight (airborne) with (Platt Saco Lowell Masterspinner) or without (Dref-2000) guidance by a duct."

A different reference has this to say about the history of open-end systems: "An early variety of OE spinning used an air vortex device. Another variety was friction spinning, but although this reached industrial production, the fine yarn version did not develop fully due to lack of yarn strength and other problems. Friction spinning for coarse yarns and core spinning did become established for a segment of the market. One successful form of friction spinning was the DREF machine in which fibers are 'rolled' into yarn by a pair of condenser rollers..."

In summary, here are the proposed changes:


 * Renaming the page to "Friction spinning"
 * Clarify that "DREF" (or "Dref") refers to a brand of friction spinner
 * Include info about "Platt Saco Lowell Masterspinner" as a type of friction spinner (I couldn't find any Google book references that actually allowed me to read the content: further research required)

Does anyone have any input on this" (, are you still interested in this page?) I don't currently feel comfortable making large changes to this article, since my knowledge of the subject is limited to the research I've done above. However, if I get no input, then I might go ahead and boldly make the edits.

 * Interested, yes. Interested enough to devote my life to it -- well.... But lets start with my frustrations. Most of the online texts are written in sub-continent English, where there is little regard to basic grammar and spelling. Most of the texts are copyvios of a single documents- and written by engineers familiar with their field so they don't explain the obvious! In the main the wikipedia article is good, but it would benefit from some in-focus diagrams or even photographs.
 * The DREF patents appear to have been used on many differing machines (spinning types)- OE and non-OE, coreless yarns, and combined with roller attenuated cores to make combined textiles.
 * So in answer to the proposals.
 * Writing about friction spinning in its entirety has many problems- we would have to go into the same level of detail about the Platt Saco Lowell product and patents and we don't have the sources. For GA, comparisons would be needed. I suspect this will involve compamy historys too.
 * Clarify that "DREF" (or "Dref") refers to a brand of friction spinner. No, it refer to a technology patent
 * Renaming the page to "Friction spinning". No. Rename it to "DREF Friction spinning" as the concept, or "DREF friction spinning". I agree that spinning should be lower case


 * I hope that is helpful- I think the first stage is to reference the article. This has some clear diagrams and descriptions including a critique of Platt Saco Lowell.  ... don't tempt me though. --ClemRutter (talk) 19:51, 19 April 2019 (UTC)


 * Thanks for the info! This is much less straightforward than I thought... I'll see what I can get done, but I'm not going to put it high on my priority list. To start with though, I'll change the title of the page to "DREF friction spinning". When I get around to it, I'll see about incorporating some references.

Strange grammar.
Some very strange grammar in the entire third sentence In the History category. Makes not a lick of sense whatsoever. Thank you. 2600:8800:700F:C500:DDED:DF39:43A:67CF (talk) 23:03, 29 May 2023 (UTC)
