A Possible Case for Wearing Natural Fibers

Morgan - 27-9-2016 at 04:39

"The impact of microplastic pollution is not fully understood but studies have suggested that it has the potential to poison the food chain, build up in animals’ digestive tracts, reduce the ability of some organisms to absorb energy from foods in the normal way and even to change the behaviour of crabs."

"Despite microfibres being the majority of microplastic pollution40,41, including in the deep-sea25,35, most feeding experiments that have been undertaken thus far use microbeads and plastic shavings, with a few exceptions, Hämer, et al.42, Watts, et al.27, Au, et al.43. Our study shows for the first time that deep-sea organisms are ingesting microfibres in a natural setting, thus we suggest that experimental designs using fibres are needed to determine the potential long-term impact of microplastics for both shallow and deep marine organisms."

"The range of plastic microfibres found ingested/internalised by organisms studied here included modified acrylic, polypropylene, viscose, polyester, and acrylic. Polypropylene has been found to adsorb PCBs (polychlorinated biphenyls), nonylphenol and DDE, an organochlorine pesticide7. Polyethylene, a type of polyolefin fibre whose chemical composition in part is the basis of some polyester fibres (e.g. polyethylene terephthalate), has been found to adsorb four times more PCBs than polypropylene44. Polypropylene has also been found to adsorb a range of metals in a marine environment; the concentrations of most of these metals did not saturate over a year period suggesting plastics in the oceans for long time periods accumulate greater concentrations of metals."

One could make an argument (and counter-argument) on the 'benefit' of natural fibers by examining the atmospheric damage involved in producing the respective natural and synthetic fibers.

Unfortunately, anything grown in nitrate enriched soil already has a negative footprint!

So, I am not sure if the advocates of natural fibers will find the results 'fitting' well with preconceived biases.

One thing I don't like about some synthetic fibers is the amount of static they produce. It's like you become a high voltage device when taking off a jacket or that amazing effect of lifting the covers at night to reveal a crackling light show. I wonder if you become a Swiffer electrostatic dust magnet? And I don't like they way synthetic fibers hang or drape unnaturally on a person. And the prilling, and the scritchy sound a synthetic jacket makes when moving in the least. Often synthetic fibers are uncomfortable to wear. Or the chemical smell from drying a synthetic blanket in the dryer on anything more than a delicate heat setting. Some synthetics make a lot of dryer lint and dust as well, although cotton flannel will do the same, a blizzard of particles quite visible in sunlight. Synthetic fibers often melt easily. And so much of this stuff is made in China now. Here's some thoughts not 100% accurate but points to ponder.

"Expensive clothing may seem overpriced, but the quality of the raw materials is superior, and the fibers can be woven into beautiful fabrics that are soft and strong, requiring little chemical processing to make them suitable for you, the consumer. They also last you for years so are a wise purchase in the long run."

"Keep in mind that many fabrics (including natural fibers) undergo significant processing that often involves:"
Detergents
Petrochemical dyes
Formaldehyde to prevent shrinkage
Volatile organic compounds (VOCs)
Dioxin-producing bleach
Chemical fabric softeners

It seems all cotton is a rarity in the typical American malls today. And sometimes if it is all cotton it's so thin and doesn't hang well. It's sad so many of our clothes are made in China by slave labor. But there's nothing wrong with cotton.

A few of the comments were informative.
"There’s a huge need for truly chemical free clothing. My blog gets thousands of hits every year from people all over the world who are searching for it. Even organic cotton clothing (and bedding) can be toxic if regular dyes and finishes are used. It’s not just formaldehyde! Sometimes the chemicals can be washed out, but other times they are permanently embedded. And washing the toxic stuff just pollutes those who live downstream… little fishies, frogs, and oops, us too! We have to drink that water! Municipal systems were not designed to remove all the toxic chemicals we dump into the water… We really need truly non-toxic, chemical free clothing!"

https://www.theguardian.com/sustainable-business/2016/nov/19...

"This year, a handful of retailers started selling cotton that had been marked with a DNA tagging system, similar to what’s been done with olive oil, Super Bowl footballs, and fine art. The technology, developed by Applied DNA Sciences, uses tiny genetic markers that are sprayed on the cotton at the gin just before being packaged and sent to be turned into yarn. The markers bind to the plant’s fibers and act as a microscopic bar code that can be tracked throughout the production process, which can involve more than seven steps in as many countries. At each stop on that journey, samples are collected and sent to Applied DNA Sciences’ lab for testing to ensure the DNA tags are still there and another cotton hasn’t been substituted."

Natural fibers tend not to melt onto your skin in a fireworks accident, wool and cotton are also pretty much self extinguishing.

So I wear a lot of cotton at work, and some wool.

Plus, I hate that static thing from the synthetics, as do some of our igniters...

Dr.Bob - 21-11-2016 at 17:53

But Nomex is great stuff for working around fire and works. But I have seen way too many people wearing synthetics while handling dangerous chemicals or working with flammables. The newest Under Armour shirts have big labels saying to keep them away from fires, likely due to campfire and kitchen incidents.

Morgan - 21-11-2016 at 19:17

There're a sea of synthetics in the stores today, especially sporting goods stores that sell Under Armour.

Congratulations! You have selected a garment made of Nomex®!
Ease of wash and care.
Launder Nomex® garments separately from other garments.
Tumble dry garments at low temperature settings or hang dry away from any light source.
Store Nomex® garments away from any light source.
http://www2.dupont.com/Public_Sector_ER/en_GB/Nomex_key_Bene...

I couldn't find out what the anti-static fibers are made of.

Nomex is the main component of many protective textiles bearing his name, including:
Nomex IIIA 2 (Nomex Comfort 3 ): 93% Nomex, Kevlar 5%, 2% antistatic fibers;
Nomex Tough ( armor serge ) and Nomex Twin (special armor): 75% Nomex, 23% Kevlar, 2% antistatic fiber 3 .
https://fr.wikipedia.org/wiki/Nomex

"Aromatic polyamides such as Nomex are often called aramids for short. Kevlar® (another DuPont textile) is also an aramid, but with a slightly different chemical structure. If you're interested, the full chemical name of Nomex is poly (m-phenylenediamine isophthalamide), while Kevlar is poly (p-phenylenediamine terephthalamide); Nomex is a meta-aramid polymer while Kevlar is a para-aramid polymer."
http://www.explainthatstuff.com/nomex.html

"Type 462 staple of NOMEX® is a blend of NOMEX®
and KEVLAR® brand fibers and P-140, a proprietary
static dissipative fiber."

"Where indoor storage is used, incandescent lighting is
preferable to fluorescent lighting because the UV
component of incandescent light in the 360-nanometer
range of the spectrum is significantly less intense. Storage
near windows should be avoided because the 360-
nanometer range of the spectrum exceeds the point at
which common window glass absorbs most UV radiation."

"The fiber contains up to 12% moisture (depending upon
storage and use conditions) and a small amount of residual
dimethylacetamide (DMAC) from the manufacturing
process. Surface coatings of lubricating and antistatic
agents, and additives designed to enhance specific product
performance, such as coloring agents and ultraviolet light
blockers, may also be present. These additives are tightly
bound within the substrate and do not present any known
hazardous exposure in handling or use."

"As produced and shipped by DuPont, NOMEX® contains
finish and moisture, and neither these components, nor the
fiber itself, have been observed to cause sensitization in
human skin tests. There is, however, potential for
sensitization as a result of the application of other additives
applied to fabrics or garments of NOMEX® during the
manufacturing or laundering processes.
Infrequent cases of skin irritation have appeared in the
initial wearings of garments of NOMEX®. The
mechanical action of wearing a stiff, unwashed fabric
can cause irritation in areas where there is restricted
movement, such as at clothing binding points, thick
seams and unfinished edges. DuPont recommends
washing a garment at least once prior to wearing. This
will remove stiffeners that are applied by fabric mills for
ease of handling in garment manufacturing."
http://www.nakedwhiz.com/gasketsafety/nomextechnicalguide.pd...

"Based on over 30 years of experience in commercial use and extensive toxicological testing, NOMEX® fiber products present minimal risk to human health and the environment."

"NOMEX® fiber is a creamy white yarn, staple, or floc that may be blended with similar forms of gold-colored KEVLAR® brand fiber. As-shipped these products pose no immediate hazard. Processing and handling can produce airborne respirable KEVLAR® fibrils (subfibers.) Animal studies indicate that prolonged overexposure to such fibrils has the potential to cause lasting lung damage. Use ventilation or a respirator to minimize fibril inhalation."

"NOMEX® aramid fibers of 2 denier per filament contain 0-2% dimethylacetamide (DMAc.) Heavier fibers may contain up to 3% DMAc. Processing and handling may result in exposure via skin absorption and inhalation. Prolonged and repeated overexposure to DMAc can cause liver damage. Wash hands after handling. Avoid exposure to hot processing in confined spaces. Use adequate ventilation. Industrial experience shows that minimal absorption of DMAc occurs from room temperature handling of NOMEX®. DMAc can be released by heating above 200C or by extracting with liquids, especially during dyeing."

Nomex is desgned for people working around naturally aspirated fires of liquid fuels and general machinery/structural materials. Not very HOT fires, in the scheme of things.

Fireworks stars, particularly metal fueled ones, BURN RIGHT THROUGH NOMEX. FAST. And if those stars are going 300 fps or more, they PUNCH right through the Nomex, it is NOT Kevlar body armor either...

I have seen a number of neophyte pyros hapily putting on Nomex jumpsuits like it was a magic flak jacket. It is not... The holes in that pretty orange jumpsuit soon educate them.

Myself, I own a bee keeper's coverall. Imagine a nice big poofy oversized white jumpsuit that closes pretty tight at all openings, made out of 100% cotton, and thick enough fabric to stop a bee stinger (about like heavy denim blue jean material).

Here's something about the proprietary anti-static fibers in some kinds of Nomex.

"composition is 93%Nomex,5%kevlar and 2% P140 ( anti-static fiber),the fiber is from Dupont,we are the exclusive partner of Dupont Nomex in China."
http://www.textile-product.com/Nomex-Kevlar-Anti-static-fabr...

"NVISTA® T420A is the only nylon fiber blend specifically engineered to be combined with cotton for higher durability and to dissipate fabric to fabric and fabric to surface static. The carbon core of the P140 fiber gives the INVISTA® T420A fiber blend its inherent static dissipative properties. Further, the P140 fibers provide inherent static dissipation that perform through wear, laundry, and even in low humidity environments."
"The P140 carbon core in the CORDURA® fabrics with T420A dissipate static through induction – the most effective form of static dissipation. Static charges on the fabric create opposite charges on the P140 carbon core fibers. When the charges on the carbon core build to a high enough energy level, air molecules around the carbon core are ionized. Air ions neutralize static charges on the fabric and thus dissipate static."

To my way of thinking, that Polyester, is in fact, spun from old pop-bottles.

When you look at the way fire retardant clothing work and when you look at what happens when you apply a flame to wool or cotton there are very few reasons that would make me buy fire retardant clothing.

But for everyday wear, especially now that winter is coming synthetic fibers are a Godsend.

Morgan - 23-11-2016 at 08:18

Good point about not using a dryer. I do that with jeans, just hang them on a coat hanger with 2 clothespins at the waist. If you want to soften them you can tumble them briefly after they're dried. Besides lasting longer it also saves energy. Also I've read you can use half the laundry soap that's recommended. I've a new largish washer and it uses so little water, barely covering the clothes, I often opt for the second rinse cycle, especially with new clothes. Some black Levi jeans made my fingers black just trying them on at the store. And probably one wash doesn't really keep it from coming off on you. I don't like to iron but if I had a lot of flat surfaces, I'd just lay my shirts out. I can't figure out how to hang shirts without clothespin crimp or line marks, even a towel rack leaves impressions.

"Last year I noticed the towels never seemed to come out perfectly clean and when they got damp after you got out of the shower they smelled dirty immediately. It turns out I was using too much washing detergent, the irony is that "too much" was how much the manufacturer recommended. One of the side effects of using too much detergent, especially on things like towels is that the detergent coats the fibers of the towel and it never gets a chance to fully dry and become fully clean—you get stuck in an endless cycle of towels that smell like they've never been washed. I reduced the amount of detergent I was using until I was using a mere 1/8th of the recommended amount. Everything from towels to t-shirts came out smelling fresher and more comfortable."

Aww. Levis aren't Levis anymore. Just cheap stuff, with the Levi label on it.

So now, the quest for quality denim seems to be eternal.

In addition to lesser quality cloth, the thread itself seems to be dyed differently. Pre-dyeing thread treatment, with Copper Sulfate, formerly embodied the finished fabric with lifelong rot resistance. Not so anymore.

"However I wanted to ask owners of specifically indigo denim if it ever stops rub off even after vinegar soaking. I have just bought 2 new pairs of dark jeans and fortunately I have only taken the tags off one pair. On first wear of the other pair today they rubbed off on my new converse, on the white rubber. Thankfully I was able to clean it off, but now I'm doubtful as to whether I want to keep the other pair if it will be problematic."

My work colleagues who go to customer sites to do electrical and/or electronic repairs have to wear 'arc flash' rated clothing,
able to accept rated joules/cm2 without melting onto skin.
So natural fibers are used.
I assume that similar considerations apply to pyrotechnics clothing.

I find that natural fibers 'breathe' allowing sweat to evaporate rather than run down my body.

Clothes made with synthetic fibers usually need little or no ironing whereas most clothes made with natural fibers need ironing.

Hanging just-washed shirts on coat-hangers allows them to dry almost crease-free.
Button the shirt and clip the hanger to the washing line to resist windage.

Please stop criticising Chinese products and start criticising the Western companies that choose to buy the cheapest crap and mark it up sky high before selling to us
ripping-off both Western consumers and Eastern workers.
- Chinese manufacturers will supply anything paid for, from plastic poo to designer clothes, iPhones etc ...
Please remember that it was USA corporate interests that kept bangging on China's door to open up it's huge potential consumer base - forgetting the historical trading and manufaturing culture of the Chinese.
When we (UK) did this we eventually depleted all of our silver and resorted to opium and war to get it back.

I happened to see some T-shirts labeled staycool temperature control on some "100% cotton" shirts and was perplexed by what it could be. So apparently there's some phase-change material in some ordinary Jockey T-shirts these days. Jockey said there was all of a gain of 3 degrees cooler than a ordinary T-shirts. On the care instructions it says tumble dry low. Somewhere I read it was a wax, and I wondered if it was something like coconut oil that melts around room temperature.
Anyway here's an example of 100% cotton with some mysterious encapsulated waxy material I don't think I'd want even if it is inert. Wonder what the threads look like under a microscope, if you could see any difference? How might the encapsulation bonded to the cotton work/adhere and what would the environmental impact be, if the particles are of any concern, like the microbead problem.?

I too, FAR prefer cotton to synthetics.

Although for a labcoat, I stick to wearing a heavy leather trenchcoat, that is, for looks, past its best, and I bought others. The reason for that, being it doesn't absorb flammables if spilled as easily as fabric, acids, bases etc. are slower to both burn through and to soak through to burn ME than a cotton labcoat would be.

Been contemplating doing what I like for leathers worn for comfort/looks with the scrappy old one (any rents in that old coat used in the lab, are at the back, which of course is unlikely to be facing something trying to cause mischief.) for leathers worn for pleasure, I like to line them with Pb dust shot in sealed plastic packets, covered by a liner
so as to provide as much extra weight as is practical and attach a few straps to go round the body for tight compression. Thought came to me the other night, why not line the scrappy old trench with lead sheet, fashioned into scale-mail not only for a more comfortable bit of clothing, but it would have the added benefit of being able to take some pretty severe punishment in case of an accident, that leather will slow, but if it were a standard cotton labcoat being worn, things like 98% H2SO4 would go straight through it, and burn the wearer. That leather trench, unmodified with compression and weighting has stood up to concentrated acid in time for it to be washed off (albeit near instantly) without causing any but minor damage. But something like sulfuric of that concentration for example, would eat through a cotton labcoat in no time flat, and soak in straight away whilst doing it, burning the wearer. Un-leaded leather coats (its a sensory thing, if anyone is wondering, auties usually like compression of the body, weighting the coat and adding leather belt-fashion bands for compression on a leather jacket several times too small, for me makes for a really quite comfy item of clothing.

But I just bet, especially if the lead were to be on the outside rather than in, that it would aid lab attire in surviving what would otherwise disintegrate the likes of cotton cloth.

Definitely more in favour of natural fibers rather than synthetics on the whole, silk aside due to the inherent cruelty involved in its manifacture, not that the likes of me could afford it, run the lab and eat, but I dislike intensely practices such as the throwing of live moth larvae into boiling H2O. As for wool..no. Just...no. The mere thought of the texture of the stuff makes my skin crawl, and I just cannot, and will not touch woolen anything. The one exception was a woolen fleece that had a fabric inner lining. That was tolerable, but it fell victim to an incident involving some manner or manners of alkyl and/or aryl R-SH, which after having to stay in the same clothing for about a week whilst the mercaptan compound(s?) worked their way out of my system (produed in-vivo as metabolite(s?) of something, not at all pleasant having odoriferous thiol derivatives in one's proximity, and when part of the total content is coming from INSIDE one, including nasal fluid, that is something most aversive, to say the very least)

So, All that clothing had to stay unchanged for the duration, and be bagged, taken to the middle of nowhere, and burnt, because there was no way in hell they could have been put into the outside household bin. The shoes and metal piercings were the only things worn which were able to be salvaged. Just think of what, for example, lower-weight alkyl mercaptans are like, then imagine producing it in your nose. For incidents which cause no physical harm to the subject experiencing them, unless Se or Te were to be involved in place of sulfur, things don't GET much more traumatic than producing them IN your nose:D

Well that bit in the middle about polyethylene being the basis of PET is flat out bullshit. Why do they think that, because they both have the words 'polyethylene'in their non-systematic names.
I hate them already.
Was anything else interesting said in the article?

On a TV program Sunday Morning this morning they mentioned China has a new policy starting January 1 this year they are no longer accepting plastic from other countries - unless it's "impossibly pure" or (99.5% pure) obviously unobtainable. Some recycling centers in the U.S. are going out of business because they can no longer sell it to China. There was a shot of a recycling center in Salem, Oregon where the plastic is just piling up. The town had to ask people to stop putting certain types of plastic in their recycling bins. The response from the public was outrage.

I find that natural fibers 'breathe' allowing sweat to evaporate rather than run down my body.


This depends mostly on how the fiber is woven and less on the choice of fiber.
You never know what you'll learn from a relation with a costume maker :)

This isn't quite accurate, which is clear from the experiences of anyone who has worn cotton and polyester clothing. Synthetic fiber can be woven to breathe, and because polyester and nylon are very strong they can be woven with tiny holes to breathe very well, but water vapor is only part of the situation. Cellulosic fibers (cotton, linen, hemp, rayon, bamboo) and silk also soak up liquid water! This isn't desirable for athletic clothing, but for casual wear it can make them feel a lot less sticky. The water of crystallization can evaporate and cools the garment.

Okay, here's the little nuggets of experience I have to contribute as a life-long home sewer from generations of the same.

If you clip your un-tailored shirts (T-shirts, sweatshirts, polo shirts) upside down with a hanger in them, the weight of the hanger pulls the wrinkles out of the shirt. If the shirt has long sleeves, pin the cuffs to the line or to the side seams of the shirt. Any clothespin marks will be on the hems or the cuffs without distorting the shoulders.

If you are drying sweaters or garments that need shaping around the shoulders, fold a towel in half, and then fold the towel over a hanger. The towel will hold the shoulders smooth like a Poor Man's Tailor's Dummy while the garment dries. The towel also helps dry it faster, with bonus points if you also change out the towel as it gets damp.

I buy cashmere and Italian merino wool sweaters from thrift stores and wear them as sweatshirts. I wash them on my machine's super-gentle cycle with only cold water, then line-dry them. It takes a lot of washes for them to shrink, and then I deliberately felt them and cut other things out of them - mittens, boot insoles, etc. Long before they shrink, I either get glue on them or moth holes send them to the salvage pile.

There is a scene starting around the 5 minute mark involving lavage that is most worrisome/horrifying in some respects. Part two of this documentary addresses micro plastics and synthetic fibers.
