If we know that nylon stretches, and we don't use it for webbing because of that, why do we use nylon for tarps and then have to mess with things like tensioners? Is there no way to get polyesther fibers made into a tarp? I know there are other, newer fibers out there that may not stretch but are expensive, but polyesther is cheap. Why has it been done this way for so long?
I think it's simply because theres not much lighter out there for the price. Most super thin fabrics are going to stretch. Plus, the amount of stretch a silnylon tarp recieves is very minimal and tolerable oppose to nylon webbing tree straps, which must support your weight constantly over long period of time, and even then, a few inches of stretch is all you'll typically get.
You could go with cuben, if you have the money. Though I've read cuben stretches very little, I have seen multiple people still using tarp tensioners on them. I'm not to sure why though.
There isn't enough light weight polyester out there. i would rather use polyester for hammock bodies but getting it the right weight and width has always been a challenge. I need my own textile mill. Then we'd be stylin'
guyline tensioners provide some protection for your tarp in high winds.
Guess I didn't think about the wind protection aspect. Thanks for the thoughts. I'm just a curious fellow I guess, although the lack of lightweight polyesther seems odd to me.
My ridge line of the tarp is 4 layers . . .
. . . that don't seam to stretch much,
also the edges are triple thickness . . . same there.

Hennessy's tarps are available in sil-nylon or PU coated polyester. The polyester tarps are about 20% heavier.

tensioners on my cuben is to save the fabric.. id rather have a tensioner give than have the center pull out tear away.
Te-wa, good thinking. Never would of thought of it that way.
i had to dig back to some convo held between Brian of OES. iirc, that info can also be found on the Mojo page of fabric that MLD uses.Quote:
