 * Task 1 - Proposed article
 * I would like to write a STUB article about the topic: 'Acid dye' that is currently an existing topic. Currently, the article starts off with an introduction and its contents include its uses (as a fiber and in the medical field), description, structures, classes, and references - as well as a table at the end compiling some dye-related terms linking to other articles. I believe that there might not be enough content on there, for example in the 'Classes of acid dyes' page in which no acid dye names are given as examples.


 * Task 2 - Outline of contributions to the article
 * As mentioned previously, I think more information should be added to the 'Classes of acid dye' section, so as to provide a more in-depth understanding of acidic dyes. The things to add could include:
 * A brief description of how they are categorized: There are three classifications of acidic dyes, which are all classified by their dyeing behaviour, including their wet fastness, migration ability, and dyeing pH.
 * Leveling acid dyes: These dyes have the lowest molecular weight of all three, and as a result will migrate more rapidly before fixation occurs. Leveling acid dyes have simple and small molecules, and will exhibit low wet fastness due to their high mobility. Thus, they are not normally suited for use as apparel fabric. They require an acidic dyebath to be applied, often using Sulphuric acid and Sodium sulphate mixtures (pH2-4), together with leveling agents such as ethoxylated fatty amines.
 * Milling acid dyes: These dyes have a higher molecule weight than Levelling dyes due to their larger molecules, meaning that they will migrate slower in comparison to Levelling dyes. Their low mobility causes them to exhibit a higher wet fastness, which is useful for dyeing wool materials. Milling acid dyes are sometimes called 'Neutral acid dyes' as they don't require an acidic dyebath, and will commonly be applied using Acetic acid (pH4-7).
 * Metal complex acid dyes: These dyes are composed of large acid dye molecules complexed with a metal ion, which will usually be chromium or cobalt. Metal complex acid dyes have the highest molecular weight of all the dyes, giving them low mobility and the highest wet fastness. Once fixed to the fiber, they will not migrate. Due to this, they are commonly used on nylon and synthetic poly-amide fibers. These dyes are very economical, however they will produce duller shades compared to the other classes. Metal complex acid dyes take a larger range of pH in the dyebath (pH2-7)
 * In the categories above, I have incorporated the original wording into the additional information I have added. I believe that the original wording had some grammatical mistakes, and so reading it would confuse the reader and prevent them from understand the article. I think that my contribution would add in relevant information whilst not changing too much of what the previous writer was trying to convey.

 * "How Acid Dye Works" Retrieved 2019-20-04


 * Task 3 - Related articles to be used as a model
 * I will use the article "Dye" as my model to be used in order to develop the "Acid dye" article. I could also add in related information about the 'Chromophore' section in more detail from the "Dye" article, for example the use of chromophoric dyes in Microbiology - to visualize nucleic acids and lipid bilayers. The "Dye" article also talks about attachment to fibers, which I could elaborate on in the "Acid dye" article on how it works.

Please also note that a similar proposal (User_talk:Myesd) has been rejected. However, one of the sciencedirect references there is more appropriate than your blogspot reference above. --Taweetham (talk) 08:21, 6 October 2019 (UTC)


 * In the sandbox I will be working on the following categories:
 * Classes of acid dyes
 * Uses
 * Description
 * References
 * I will also have to change some of the links. For example, the original would link pages for 'Synthetic' and 'Nylon' multiple times, or have links for 'hair' or 'protein' that I do not think are too related to the article. It looks excessive and unnecessary.

PanisaLuengthada (talk) 14:39, 10 October 2019 (UTC)

Actually, ajarn, I'm not sure about the last part. If the original article had links to pages like 'hair', which is a common word that shouldnt need explaining, would it be better to delete it? Also, if the links are repeated, do I delete the repeat links after the first one or is it okay to repeat the links? PanisaLuengthada (talk) 13:09, 12 October 2019 (UTC)

Hi PanisaLuengthada! Please continue to improve your nominated article Acid dye.

--Taweetham (talk) 06:54, 3 November 2019 (UTC)
 * Ajarn, I just made some changes to the article which is shown in my sandbox. I added 2 pictures to show the effect of 2 acid dyes (Lee's stain and PTAH stain) as well as further explaining what acid dyes are used for in the medical field and why. Could you please review this and tell me if its okay or not, so I can move it to the article? Thank you in advance. PanisaLuengthada (talk) 13:41, 5 November 2019 (UTC)

 * Please make sure that you format you reference "Gokhale, S (2008)" properly.
 * Please have a look at https://www.sciencedirect.com/science/article/pii/B9781845696955500155

You are now assigned a mentor. --Taweetham (talk) 06:00, 16 November 2019 (UTC)
 * Hi ajarn, I just changed the Gokhale reference so that the 'access url' was removed (it does not have one as it is a book) in the Acid dye page. I also added content to the article in my sandbox under the 'food industry' section, could you please have a look and approve/disapprove it so I could make further changes? Thank you in advance. PanisaLuengthada (talk) 16:19, 16 November 2019 (UTC)
 * Please WP:Be Bold and edit the article. From a quick look, I see reference errors (shown in red in reference section) and unnecessary capitalization of words. Apart from that, it should be fine. --Taweetham (talk) 02:33, 17 November 2019 (UTC)

ICCH224 Week 11
Your mentor will provide detailed feedback soon. I have identified a number of problems at this point: --Taweetham (talk) 07:37, 23 November 2019 (UTC)
 * 1) The title paragraph as it read now indicates that the subject is only applied to textile.  However, the Uses Section expands this to Medicine and Food Industry Subsections.  Make sure you understand the connection and revise the content to be consistent.
 * 2) Structures Section is not well-referenced.
 * 3) Classes of acid dyes Section may have a conflicting information with Description Section.   Make sure you understand the connection and revise the content to be consistent.
 * 4) Health hazards section raises some concerns. Is this WP:NOT? (General warning for each of the acid dye compounds is usually WP:NOT.) Is it carcinogenic as a pure compound or as a textile or both?  Are there any safer alternatives or mitigation measures? If you can answer these questions, you can probably revised the section to be encyclopedic.
 * 5) Please provide sufficient internal links so that readers can understand your text.
 * I agree with ajarn Taweetham about the title paragraph in which it does not give the overall picture of what the acid dye is. I want to add that for the structure section, there is no connection between texts and pictures. I do not know which picture is referring to which types, you should elaborate more on that part as well--Teetee taw (talk) 13:13, 24 November 2019 (UTC)
 * Hi ajarn and p' teetee, I fixed: error number 1 (by adding text that its related to the food/medicine industry as well - mobile edit).
 * error number 3 (erased the description's section information about the three types of dyes because this was incorrect).
 * error number 5 (added more links for 'mutations', 'endothermic', 'pKa', 'dissolution' (solvation), 'mitochondria', 'nuclei', 'collagen' and 'cytoplasm')
 * However for the structures section, I dont know what to do as I didnt make that section or contribute anything to it. I went to the reference the previous editor had linked and it wouldnt give me access so I was unable to fix the references or link the different pictures to each type. Also, could you elaborate more on why the health hazards section is WP:NOT? I took a look at it and I'm a bit confused because the section isnt promotional, a dictionary, a promotion of original thought, a guideline, blog, etc. Thank you PanisaLuengthada (talk) 05:31, 30 November 2019 (UTC)
 * I followed P' Teetee's advice and removed the health hazard section, bringing the content to the description section instead. PanisaLuengthada (talk) 11:49, 6 December 2019 (UTC)
