In real life, it is common for certain clothing manufacturers to use metal rivets to reinforce the pockets of their pants and shorts, especially ones made from cotton or denim. The practice was purportedly started by Levi Strauss himself, who kept hearing complaints from miners about how their tools would tear their pockets apart.
Well, after watching several hours of Mythbusters on the Science Channel last night, I had a dream in which the Build Team was assigned to test whether or not rivets actually weakened the clothing that they were inserted into.
The "myth", IIRC, was that if a person sweated enough, the sweat would get at the rivets and the fabric around where the rivets were mounted, thus tearing them apart slightly faster than the regular material. I seem to recall that the method of testing involved lengthy periods of high-intensity aerobics while wearing denim clothing that had rivets in them.
So - is it even vaguely possible that sweat can cause rivets to "fail" somehow?

So - is it even vaguely possible that sweat can cause rivets to "fail" somehow? it would require one of two conditions to be present: either the cloth under the rivet would have to be weakened, or the metal of the rivet would have to fail. one possibility would be that the process of inserting the rivet cut the fibers where the rivet was inserted, thus increasing the possibility of the cloth failing due to the cut fibers pulling out of the rivet. the best example of this would be the grommets pulling out of plastic tarps.

Depends on what the rivets are made from. If you are talking about iron in some form then yes, sweat could cause them to fail. Sweat contains salt, which speeds up rusting and of course weakens the metal. Rust itself will not do fabric any favors, especially if impacted into the fibers around a rivet that are being twisted, since it is abrasive.
I remember catching a program a LONG time ago that claimed that the original jeans had the pockets (or at least the ones at the back) entirely riveted in place - or possibly heavily riveted. These were unpopular as anyone who stood with their back to a fire ended up with a lot of hot metal rivets pressing against their backside.
Maybe one or two additional 'jeans' or rivet myths added to this might make things more tempting from the shows prospective - The idea is in and of itself rather a good one, but might be a little light on content on its own.

I am trying to remember, now, whether I have overheated any of the remaining rivets in my work pants, and I think I might have. I do know that rivets fresh out of the dryer can inspire some interesting dance steps.

It is more likely that I'm misremembering what was shown on the program, rather than the program itself being wrong.

So let's see:
1. Can sweat cause riveted clothing to fail, either near the rivets or at the rivets? * Will sweat cause the rivets to corrode enough to speed up failure? * Will sweat cause the material near the rivets to corrode enough to speed up failure?
2. Can rivets transfer heat or cold to the wearer? * Can a person who wears riveted clothing feel the temperature difference if their rivets heat or cool? * Can the rivets transfer enough heat / cold long enough to injure the wearer?
That's two myths right there.

#1 is more to the point of can rivets really become a failure point under certain conditions?
#3: do pants with rivets increase your likelihood of being pulled aside at the airport? - the question is whether the TSA will cooperate with this, though it is not really a security issue - they just like to keep quiet about their tech.

The team could simply see about renting one of the "wand" devices that the security people use.

I can tell you that the wands sensitivity can be altered to ignore Clothing rivets, zips, and other metal fastenings. Also the operator may choose to ignore such signals. It is expected that Zips and Jeans will have small metallic signatures. They are after BIG things such as knife blades that have a much bigger signal return?....
The rivets themselves.... I think it may have been the Discovery program "How its made", but I watched how jeans were made one time?... The inference was that the continued use of rivets these days was purely a traditional thing, the rivets in use today are not as strong as the original ones, and are only put in "For show", as people buying jeans expect to see Rivets. And again, the ones I am wearing today dont have any rivets at all. I am working on something in the back yard, its rather messy, and as usual, it will get on my clothing.... I trash more jeans by Dirt Grease and Oil stains than I do by wear alone, and at a fiver a pop, the ones I use, bought from ASDA (Wally World), are perfectly serviceable, and disposable as bio-degradable when they get too dirty?...
Of Course, certain brands still make the original recipe.... it works and they refuse to "Fix" it...same weight denim, same thread count, same exact way as they have always done.
I keep some decent jeans for when I need to be smart but serviceable... as in driving the Truck.. its still shirt-and-tie, but they dont expect pressed seam trousers or suits when you drive the heavy stuff.
And I remember the day I had to teach my Dad how to iron jeans.... Mum was ill, Dad was trying to help out, with Ironing, he was about to put creases in Jeans?.... I was about 20 at the time. To his amusement, I grabbed the jeans, told him to "Follow me".... I then lifted the mattress, placed the jeans folded in half lengthways under the mattress, and said "Jobs done, come back tomorrow..."
Mum was laughing at the look on my Dads face. He had never been a "Student", never lived in Digs, and never used the lazy trick of flattening jeans under the mattress....
I do hope this isnt a strange thing to other people?... surely some others out there have heard of (and used) that trick?....
Jeans are what they are. The places where they "Rivet" jeans are usually strong parts, they push the rivet through, not punch, so the fibres are parted rather than damaged, and the pressure put on the rivet as it grabs hold is enough to keep and increase the strength of the fibres around the joint.
Its a simple good strong trick.
If sweat and dirt are enough to cause failure, the fibres around the riveted part will fail first, or the thread holding seams together. In all the years I have worn jeans, over half a century, by the time the rivets fail, they are usually the least of the problems you have with that pair of jeans.
My worst area of wear has always been the knees, or that area between knees and waist, as that is where my jeans get the most wear in the workshop, rubbing against bits I am working on or spillages.
The worst thing you can get on jeans, by far, is Line cleaner. [Other than stuff that is complete call the fire brigade environmental seal off the area hazardous chemical that should never be handled without specialised clothing....] The stuff any Bar Pub or Restaurant uses to clean the lines from barrel to tap, line cleaner, is that caustic that any spill on clothing will wreck it almost immediately, doesnt matter how quick you get it in the wash, its going to degrade right here, right now.
And line cleaner that DOESN'T do that is not worth using......
So I have wrecked a few pairs of jeans cleaning the lines in the Pub. I have a heavy leather apron that I use to prevent splashes getting on me, but it doesnt go all the way to the floor, so from about knee height down, I am exposed to splashes.
As for the rivets themselves, that they use in jeans, I believed they were a form of either Stainless steel or Aluminium. Neither will degrade that quickly in normal use?....

I have never ironed a pair of jeans in my life. and when my college girlfriend's mother ironed a pair of jeans (I think I had taken ill during a visit) for me, I found it quite odd.
ironing is for clothes that are supposed to have creases.
as for material, most rivets I have contact with are made from brass, and the only abrupt rivet failure I have dealt with had more to do with a bird than with normal wear.

Wouldn't the first point of business be to find out if the rivets themselves are weakening the cloth to begin with? If they are, then there's instantly something to this myth, making the places the rivets are inserted into more or less pre-determined points of failure. From there it's just a matter of finding out if sweat could possibly accelerate the failure process.

my work pants typically fail either in the knees, or along the seam at the top of the leg double leg panel.

Its not that rivets dont wear out, its more that they are supposed to lengthen the life of the seam?....

I don't buy riveted jeans (waste of money for what I'm normally doing), but I think Silver's point about how the rivets are set is a good one. In re-enactment circles, there's a lot of people who argue that you shouldn't use metal eyelets in your corset because the process of setting them cuts the fabric -- they recommend using an awl to shove the threads aside to make a small hole, then a knitting needle to force the hole large enough for your cording, then sewing around the hole. (And if I can ever find someone local who can help me fit an Elizabethan corset, I'll be able to test this. That's not something you can fit to yourself without help.)

I thought the principle behind an elizabethan corset was to reshape your body to match the corset, rather than the other way around...

Any corset will reshape to some extent, but the radical reshaping would be Victorian. Elizabethan basically smooths the torso. And any garment that fits that close (of any era) had better be fitted correctly or it's going to be painful at best. [/hijack]

To get this back on track after the corset detour, I did some checking online. Depends on what the rivets are made from. If you are talking about iron in some form then yes, sweat could cause them to fail. Sweat contains salt, which speeds up rusting and of course weakens the metal. Rust itself will not do fabric any favors, especially if impacted into the fibers around a rivet that are being twisted, since it is abrasive. According to the History Channel's "This Day In History", the Levi Strauss patent was for copper-riveted jeans. The search function on the US Patent Office website isn't all that great, I'm still trying to find out additional details on the rivets.
