Tussah

Maybe Tussah should get its own subsection describing it. It's not really a type of silk, but a different way of harvesting silk. —Preceding unsigned comment added by 68.9.59.55 (talk) 04:48, 31 December 2007 (UTC)

Yes Tussah should have its own subsection- where most silk worms eat only one species (Bombyx eat only mullberry) the Tussah, or wild, silk worms live naturally in tropical or semi-tropical forests. Their silk is gathered after the moth emerges. The caterpillars eat all kinds of different trees, all rich in tannin, so the silk is beige to brownish toned. This fibre is naturally golden, very long staple (3"+), strong, lustrous, and more resilient than cultivated "white" silks. It dyes beautifully, with colours slightly muted by the soft undertone of beige. from AuroraSilk.com - Cheryl Kolander author of :Silk Workers Notebook, 3rd ed. —Preceding unsigned comment added by 24.21.192.115 (talk) 23:05, 25 January 2008 (UTC)

Odyssey Reference (19.232-235)

In the Odyssey, 19.233, it is mentioned that Odysseus wore a shirt "gleaming like the skin of an onion" (varies with translations, literal translation requested).

The comparison of Odysseus' tunic to the skin of a *dried* onion is actually on two grounds: (a) that it glistened, and (b) that it wrapped the body perfectly due to its softness. Furthermore, verse 235 is somewhat ambiguous, but one of the possible interpretations is that many women (who also made clothes for their families) wondered about the fabric and/or the weaver's skill. The original text reads:

τὸν δὲ χιτῶν' ἐνόησα περὶ χροῒ σιγαλόεντα,
οἷόν τε κρομύοιο λοπὸν κάτα ἰσχαλέοιο·
τὼς μὲν ἔην μαλακός, λαμπρὸς δ' ἦν ἠέλιος ὥς.
ἦ μὲν πολλαί γ' αὐτὸν ἐθηήσαντο γυναῖκες.

And I noted the tunic about his body, all shining
as is the sheen upon the skin of a dried onion,
so soft it was; and it glistened like the sun.
Verily many women gazed at him in wonder.

(The English translation comes from http://www.perseus.org)

Post-Byzantine Literary Reference

A very close parallel can be found in Erotokritos, the famous 17th century romance by Vincenzo Kornaros written in the Cretan dialect. In Part II, v. 415-420 the poet describes the (fictional) Prince of Byzantium as he appears before his host, the (fictional) King of Athens:

Eφόρειε κάποιαν φορεσάν, π' όσοι κι αν τη θωρούσι,
ίντά'ναι, πώς να γίνηκε, δεν ξεύρουσι να πούσι·
ήλαμπε τόσο κ' ήστραφτε, που κάθε φως θαμπώνει,
και η λαμπυράδα τση η πολλή την ομορφιάν τση χώνει·
γιατί δεν ήτον μπορετό κιανείς να του σιμώσει,
και [η ακτίνα] τω' ρουχώ' να μην τον-ε θαμπώσει.

He wore a certain dress, which none that looked at it
could say what it was or how it was made;
it glowed and shone so much that it dimmed all other lights
and took its beauty from its great shimmer;
for it was not possible for anyone to go near him
without being dazzled by [the radiance] of his clothes.
(Ad hoc translation from Cretan Greek into English)

This is arguably an allusion to the silk riches of the Byzantine Empire and, most likely, a direct reference to the Odyssey itself.

Trade Expansion

<blockqhuote>Perhaps the first evidence of the silk trade is that of an Egyptian mummy of 1070 BC. In subsequent coenturies, the silk trade reached as far as the Indian subcontinent, the Middle East, Europe, and North Africa.

Egypt is farther from China than India or the Middle East, so how does it make sense that expansion to those areahs happened "in subslequent centuries"? Nakamura2828 17:55, 17 November 2006 (UTC)

silk-producing goats

Someone with greater interest in the topic could push this info into the article:

Jeffrey Turner or Nexia Biotechnologies developed silk-producing goats. =)

By injecting the orb weaver gene into the father of Mille and Muscade, Nexia bred she-goats whose mammary glands are able to produce the complex proteins that make up spider silk. Their milk looks and tastes like the real thing, but once its proteins are filtered and purified into a fine white powder, they can be spun into tough thread. [1]

Mommes Merger

Mommes is an orphan article that is only linked to from here. I can't think of any other article for which it will be useful to link directly to unit of measure for silk. Any objection to simply merging the article into this one? QuixoticKate 19:48, 11 January 2007 (UTC)

I always support merging orphans, but how about a page for Units of textile measurement? We could include Denier (measure), Tex (unit), Thread count and Thread (unit of measurement) (a cotton yarn measure, equal to 54 inches according to the Thread disambiguation page). (I couldn't find any others.) Tocharianne 21:13, 11 January 2007 (UTC)

That's a really interesting idea, but I'm not sure how to implement it. The other articles you've named aren't really orphans themselves (5-10 links each). Would we redirect all of those articles to the units of textile measurement article? Maybe the solution is to just create a "Units of Textile Measurement" category. I'm not sure it that really solves the orphan problem, but even though other units of measure have the same problem (see Abcoulomb in Category:Units of electrical charge, for example). QuixoticKate 16:25, 17 January 2007 (UTC)

It's true they're not orphans, but they are stubs. (I always support merging stubs, too!) They basically are just different ways of referring to the same thing: the "density" of a fabric. The tex (unit) article says that the difference between tex/denier is just UK vs. US English, and the mommes article says that it's the silk equivalent of thread count. Tocharianne 17:04, 20 January 2007 (UTC)

Fair enough. I'm persuaded that your proposal is the best solution, and I think I'm just going to go ahead and do that once I have time to do so unless anyone else weighs in in the meantime. QuixoticKate 17:51, 22 January 2007 (UTC)

Silk as Mongol Armor

Can anyone try to go find verifications of the mongols under Khan using silk as part of their light armor as protection against arrows? I will go look myself, because this actually seems to make some sense to me. Ulgar 18:25, 17 April 2007 (UTC)

Well that was quick. A google search of "Mongol Armor" led me right back to Wikipedia, http://en.wikipedia.org/wiki/Mongolian_armour and lo, and behold, I found that it was right there in "Mongolian Armor". Therefore, I suggest that the Citation Needed be taken off. Sound good to everyone? —The preceding unsigned comment was added by Ulgar (talk • contribs) 18:29, 17 April 2007 (UTC).

I removed the citation tag and added a wikilink to Mongolian armour. Tocharianne 23:26, 17 April 2007 (UTC)

Thanks for that, but another citation tag popped up for the claim that silk would be unbroken by the arrow head and arrows could therefore be easily pulled out of the "wounded" just by tugging at the silk shirt. I did another search, and found two sites (one linking to the second) that make such a statement. http://members.tripod.com/~whitebard/ca6.htm http://www.sfusd.k12.ca.us/schwww/sch618/War/WarArmor.html

The thing is, is that I'm not sure exactly how "expert" enough these sites are to verify the statements, and even if the numbers of sites saying this makes a point because these sites could have gotten their information from one another.

I have seen it mentioned enough times to adequately believe that this is doable and has been done with silk undershirts by the Mongols. I propose the removal of even that tag and making the section referencing Mongol use of silk not need more citing. Ulgar 15:47, 10 May 2007 (UTC)

Bothersome Ulgar is back again. The paragraph is in the "other uses" section. The first paragraph in the section is just a collection of sentences all about random different uses of silk. The mongolian use of silk is a focused paragraph, and yet second to the miscellanious uses paragraph, messing a bit with the flow. I was going to just reverse the paragraphs (I still will for now) but looking up, I realized that if there's enough of a mention and resource for it, the subject could go under the Uses in History section or whatever, about Genghis Khan's Mongolian Empire. I'm not so bold yet, as things like citations and references are pending, but I want people to consider these things. Ulgar 15:58, 10 May 2007 (UTC)

I believe that silk undershirts were also common in the west for the same reason. However while I have heard this from a number of re-enactors and museum staff I cannot find a referecne at the moment. If I find one I will come back and update this entry Arachrah (talk) 19:48, 3 May 2009 (UTC)

Properties

The Properties section contains the following statement: "Its denier is 4.5 g/d when dry and 2.8-4.0 g/d when moist." Denier is a link to another article at Wikipedia that says denier is the mass of a 9,000-meter-long fabric fiber or filament, and the unit is based on silk, of which a 9,000-meter-long filament weighs one gram. Therefore, silk has a denier of one. From the denier article: "The denier has its standard based in nature, a single strand of silk is one denier." Furthermore, the denier article makes no mention of a unit of measurement like "g/d" as it is described for silk. In the statement, "Its denier is 4.5 g/d when dry and 2.8-4.0 g/d when moist," where are these numbers coming from? Where is this unit "g/d" coming from? According to the denier article, silk has a denier of 1, plain and simple, and the silk article should say so. It might even be a point of interest to note that the measurement (denier) is itself based on silk. JJR512 (talk) 18:00, 10 June 2010 (UTC)

"denier" is a unit of measurement, not a property. Colloquially it it might be okay to speak of a fiber's "denier" as you would of a container's "liters," but the proper terms are "linear density" and "volume." And as JJR512 wrote, the linear density of silk is exactly 1 denier by its original definition. The "g/d" units cited are ...wtf? The standard unit for lin. density is the "tex" anyway. Vreejack (talk) 18:59, 9 July 2010 (UTC)

Removed the weird linear density comments (is 4.5 g/d when dry and 2.8-4.0 g/d when moist) and referred to silk as the standard for the den. Also added a little table comparing moth and spider silk weights. It's just a taste. A lot more could be done. This section needs work. Vreejack (talk) 20:12, 9 July 2010 (UTC)

This article should say something about the physical and chemical properties of silk. E.g. isn't it one of the strongest known substance (tensile strength) for its weight? Or am I confusing it with spider's 'silk'? Ben Finn 17:58, 20 April 2007 (UTC)

Though silk is strong, you are confusing it with Spider Silk. It should still say physical properties of silk somewhere down the road. Ulgar 03:31, 11 May 2007 (UTC)

Weighting

Someone ought to add a section describing the historical and possibly ongoing practice of "weighting"-- adding weight to-- silk by treating it with various chemical compounds, particularly those based on metals. Because silk is sold by weight, the practice increased the selling price of the silk.

Indian silk

This was added by 61.2.4.160, (19 November 2008), and was ewmoved "opining needs reference". Still it would be to find out more about coloring silk in natural ways.

As opined by Pandit Haraprasad Sashtri, silk production was quite prevalent in India as early as 600B.C.What is more interesting is that naturally coloured silks were produce by feeding the silkworms with leaves of different trees

Researchers from the Institute of Materials Research and Engineering (IMRE) in Singapore have discovered a way to create “intrinsically colored” silk by stuffing the worms with a mixture of mulberry leaves and fluorescent dyes.

Why this image?

There are plenty of wonderful pictures which would illustrate much better the Chinese silk than this dark, big scroll, showing some barely visible mountains, which has nothing to do with silk, except for that this dark brown painting happens to be executed on silk.

This image really doesn't add much value to the article compared whit what is available otherwise.

There are huge amounts of ancient Chuinese drawings and paintings on Commons that show silk production, ancient Chinese working with silk, wearing silk, painting silk and so on, and all of the would fit in much better in this article. Just take a look at them here .

Bulletproof?

I have no idea how true this is but I heard somewhere that silk is bulletproof. There were cases in the west were a silk bandana, while not preventing a bullet penetrating the skull, had no itself been broken. If this is true or there is any evidence, does this merit a place in the article? The reason I ask is that I'm a chemistry undergraduate doing a tutorial on polymer chemistry and have a question along the lines of why is Kevlar used in bulletproof vests and silk used to make tights, not the other way round?

See Ballistic_vest. Short mention in this article makes sense, with link to ballistic vest. Bob98133 (talk) 13:40, 20 May 2009 (UTC)

Gandhi opposed silk production?

Currently in the Animal Rights section of the article we have the following text:

Mahatma Gandhi was also critical of silk production based on the Ahimsa philosophy "not to hurt any living thing." This led to Gandhi's promotion of cotton spinning machines, an example of which can be seen at the Gandhi Institute.

This does not concord with my understanding of why Gandhi promoted village level production of cotton and sounds quite dubious to me. I do understand that there are elements of Indian religious culture, particularly the Jains, who would take a position against silk but I am sceptical that Gandhi did unless someone provides a good reference. I have added a citation needed tag to this section of text. The next step, if no-one provides one, will be deletion. Oska (talk) 06:44, 15 June 2009 (UTC)

I agree, but I think that this is just poorly stated. I think that the first sentence can be referenced, but I do not believe that Gandhi's promotion of cotton spinning machines was related to his distaste for silk. I would say that the second sentence could be deleted since it is not relevant to silk. The first sentence could use a fact tag, too, since it should have a reference.

Human Rights

I'm not familiar with editing wikipedia, or its policies, so I'm not going to do this. But it seems odd to me that there's a section on "Animal Rights" but nothing on the deplorable conditions that children work under in India to produce silk. It's basically slavery. Burn scars, infection and disease are par for the course for children "as young as five". However, I can't find any more recent reporting than 2003 from Human Rights Watch.

These appendices of mine are mostly a series of quotes from other people, and together represent quite a wide collection of information on wild silks. If anyone objects to my referral to my own work, please say so and, if possible, provide other references for this section; alternatively, I could extract the references to the quotes from others I have given in my works, which would illustrate the information in this section.

Silk Sources

"The protein fibre of silk is composed mainly of fibroin and produced by certain insect larvae to form cocoons." < Silk is also produced by spiders, those nasty GMO silk goats, a "synthetic spider silk" (apparently used in making many things, including bulletproof vests (wow)), and general synthetic silk... So, WTF is that sentence doing claiming all silk comes from the one type of source? They even put a citation for that sentence, as if that's not one of the most commonly known facts about silk on Earth. And, the introductory bit of the wikia article carries on like that until the last two sentences. My guess is that a different editor added the sentences to fix it, but did not work it in in a way that got rid of it initially pretending that cocoons are the sole source. --174.19.244.195 (talk) 10:27, 18 April 2014 (UTC)

Here is a site that looks like a blog but may also be a commercial site; I'm not sure: [2]

If that is an acceptable source, then perhaps the definition there would be appropriate for the article. If not, then I'll keep looking. I think mention of peace silk would add to the article if a reliable source can be found. CorinneSD (talk) 01:11, 24 November 2014 (UTC)

The colors and details of the pictures in the first gallery are fainter because the painting, Sericulture by Liang Kai at the Cleveland Museum of Art, is over 700 years old. The pictures are more historically significant and informative than those in the second gallery. Based on the Wikimedia Commons description, the pictures in the second gallery are by an unknown artist from an obscure book written in the 1920s. That book, Everyday Life in Old China, isn't even available on WorldCat. --MuseumGeek (talk) 15:43, 19 December 2014 (UTC)

It is known as "Paat" in eastern India!

It is known as "Paat" in eastern India is a wrong info. In Assam "Paat" or "Pat" is "a type of Mulberry Silk", not silk itself. In West Bengal "Paat" means "Jute". - দিব্য দত্ত (talk) 14:18, 29 January 2016 (UTC)

Silk of Catanzaro ?

In the Middle Ages the Venetians imported large quantities of silk from Asia and Greece especially from the Peloponnese. After 1400 with the conquest of the territories in North Italy, they started to produce silk locally. I read about ships on their way to Palermo, but I've never seen texts or books that specifically cite the silk of Catanzaro for the Middle Ages. I think that tour guide is no reliable source for an encyclopedia, it is necessary something better.

The song of this text seems hyperbolic: "..Catanzaro became the lace capital of the world with a large silkworm breeding facility that produced all the laces and linens used in the Vatican. The city was world-famous for its fine fabrication of silks, velvets, damasks and brocades..." — Preceding unsigned comment added by 93.34.228.90 (talk) 17:19, 7 November 2016 (UTC)

Silk as a biomaterial

I would like to add some applications of silk as a biomaterial, which is an important area. Yuntengcao (talk) 04:00, 29 April 2017 (UTC)

I have added an instruction on the great potential of silk serving as a biomaterial by stating that silk meets almost all the requirements for a biomaterial, especially mechanical preperties, biocompatability and biodegradability.

As stated, silk can be easily fabricated into various formats--scaffolds, films, gels--to meet the needs of tissue engineering. Those methods, which instruct people how to prepare various silk formats, is very helpful and should be added.

YTCAO17 (talk) 22:32, 16 May 2017 (UTC)

I agree that adding another section on Silk Biomaterial is important to keep readers up to date on the advancement of this field. There has been significant improvement in the field of tissue regeneration. The product Silk Voice, made by Sofregen Medical, is the first product to receive FDA clearance for human medical use. The product works to restore a patient's voice quality. I think it's meaningful to include. — Preceding unsigned comment added by Ahoang801 (talk • contribs) 17:57, 7 April 2021 (UTC)

Silk is also edible it is also super nutritious from all the protein it has you can make protein shakes with them. How to make silk protein shakes first you need one bolt of PURE silk then you crunch up the silk with something then after put the silk in a blender. after you then need protein powder fruits that you like and favorite yogurt.

Sentence rewrite needed, please

The first sentence of the second paragraph ("Silk is produced by...") needs rewritten. Perhaps some punctuation (commas) is needed to make it make sense.173.90.65.191 (talk) 03:30, 9 February 2019 (UTC)

Upon further reflection, removing the words "like silk worms" and adding the punctuation would work: Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. 173.90.65.191 (talk) 03:40, 9 February 2019 (UTC)

Agreed, I've made the change as suggested - thanks. Pastychomper (talk) 13:20, 11 February 2019 (UTC)

Silk on Egyptian mummies?

«The first evidence of the long distance silk trade is the finding of silk in the hair of an Egyptian mummy of the 21st dynasty, c.1070 BC.» it says in this article, but the 'proof' is a disputed find from 1993. Irene Good at Harvard University writes in an article from 2002: «A subsequent examination of the Deir al Medina mummy has thrown serious doubt on the interpretation of this find, however, which is most likely a remnant of a 20th century conservation treatment.»

length

the biggest difference between the wild and commecial silk is the LENGTH which is said and explained exactly once. where does this information come from and what are the lengths needed. eg sheep wool is curly and is easily spon with 'short' fiber/hair. Cotton is fluffy and real short. Silk is Not curly and Not edged or fluffy so i expect it to be "slippery" aka smooth as it feel. without resistence off the fiber itself its more difficult to spin (or weeve at micro-level!), then what are those lengths needed and what are the legths found in the wild. Is it possible to select fibers at length ?? — Preceding unsigned comment added by 85.149.83.125 (talk) 21:17, 21 November 2022 (UTC)

Aside from silk being one of the strongest fabrics, silk is also a hypoallergenic fabric that is durable and also has healing properties. Silk is a very well-known natural fabric that is very luxurious and elegant and the good thing about it is that when wearing it in the cold winter climate it retains body heat and when wearing it in the hot summer weather it eliminates extra heat.

Addition/Edit for Properties

Mechanical Properties

Silk is a natural bio-composite, the brin filaments serve as the reinforcement phase and the sericin as the matrix phase. The brin contributes impressive stiffness and strength to the composite while the sericin is responsible for load transfer and binding the brin together.^[1] Like all biofibers, the mechanical properties of silk can vary dramatically depending on sourcing and processing. The tensile strength of Bombyx mori silk typically falls anywhere in the range of 0.1-1 GPa, comparable to some grades of steel. Elongation at break is between 15 and 35 %, making the toughness/breaking energy roughly 6x10⁴ J/kg.^[2] Comparably, Tussah silk fibers (from wild silkworms) have a similar ultimate tensile strength but show a marked improvement in elongation at break. This increased toughness is a result of a relatively high proportion of amorphous structure in the fibers, as opposed to the highly crystalline nature of the Bombyx mori fibers.^[3]

Silk fibers used in the textile industry undergo a degumming process in which the sericin is removed via boiling in an alkali soap solution to break the peptide bonds which hold it together.^[4] Sericin removal eliminates the stickiness of natural silk fiber, a necessity for weaving, but also eliminates silk’s natural load transfer mechanism. As a result, processed silk has a lower elongation and toughness than unprocessed silk.

It is important to note that relative humidity can have a dramatic effect on the strength of silk. A study performed in 2012 showed a linear decrease in tensile strength of both the warp and weft directions with increasing relative humidity at room temperature.^[5] This loss in strength is due to the hydrolysis of existing hydrogen bonds in the fiber, decreasing chain-to-chain interactions and therefore increasing chain mobility.
