If not using tensioners, I've seemed to notice my silnylon tarp is looser after the temp drops (overnight) but seems to draw(tighten) when the temp rises (during the day). None of this due to any rain, fog, etc...

Nacra533 Thank you,
I was hoping you would come back with some more information. I figured you had a whole lot of material/sailing/design/engineering data to offer to this discussion. After reading what you posted in your first two posts I kinda knew you would be one of the main players.
And Mtncmpr it seems that you have experienced stretch without moisture being the catalyst.
There seems to be more to this thing than what at first seems to maybe not exist. When it comes to material characteristics I think there has to be more research data then we layman know exists.

Mtncmpr, Is it possible your bodyweight in the hammock during the night is bending the trees. And during the day your not in the hammock, the trees are straight.
I've had it happen before.
If the trees of choice are smaller-sized, my body weight has an effect on how the tarp stays tensioned.

That could be a factor at times I guess, I'm not sure, I'll keep a watch out for that. I also have noticed this happen when I was tent camping. I was always curious as to why the material (nylon) on the Rain-Fly would begin loosening up at night after being set up taught (and with no one in it), and then tighten up again during a sunny day (no one in it).
Please note: My point (on my posts) is water is not involved.

I saw some interesting info posted on Brian's site about fabrics, if you haven't read it yet...
http://www.outdoorequipmentsupplier.com/fabric.html
It doesn't have some of the exact specifics you may be looking for, but it does have quite a bit of comparative information on the fabrics.
Hope that helps you out.

Hey, does anybody know whether lighter or heavier silnylon stretches more?
I have to choose whether to make something out of 1.3 oz or 1.9 oz fabric, weight isn't important in this case, but elasticity is.
They both should stretch about the same...however, they will do it at differing load points. The heavier nylon will require an heavier load to stretch to the same distance as the lighter nylon (same as with their breaking points). Note that this assumes a similar thread count, nylon quality, and coating quality between fabrics.
Hope it helps!
