I bought some material from Wal-Mart, and I'm not sure what it is exactly. I know it is rip stop nylon, but it has some kind of finish also. It isn't completely waterproof. What I did to test the waterproofness of this fabric was rubberband a peice of the fabric over the opening of a drinking glass and made a depression in the fabric to hold water. After a littlewhile, I checked back and there were only a few drops slipping through. Before I did this I made sure the fabric was saturated. I also did the same thing with a dry piece of cloth, and even less water got through. SO, to make a long question a little shorter...what fabric do I have? Anyone have any idea? I also did a breathability test to the fabric and it is somewhat breathable, but not by much.
My plan is to make a tarp with material since there will be a ridgeline causing water to run off and there will be no standing water on this fabric. I think it will work, but I wanted some opinions on this issue. Thanks all!
