Hello all, new guy here. Howdy!
First off, been reading for quite some time, finally decided to jump in. Great site... already making a big difference in my Utah desert trips.
After following many of the WallyWorld 'silnylon' threads, I stopped by a local store and found a bolt of '$1 mystery fabric', in MARPAT camo no less. So now I'm trying to figure out exactly what it is, and more importantly...
What should I make out of it?! lol
I got 15 yards total.
Properties: ripstop nylon. lightweight. One side appears slightly dull in comparison with the other. The dull side is less 'slippery' as well, so I don't think it's silnylon.
My totally scientific double blind controlled experiments...
Blow test: Couldn't force air through fabric. Nice old lady working the fabric counter asked me to stop licking the goods. Talked her into letting me have an piece to take to the bathroom. Couldn't get water from faucet to penetrate.
Water test: Put a square over a full mason jar and fastened with a band. Inverted and put in another jar and left overnight. No water through. (sorry for the pic quality)
Wind test: Attached a square to my car for this mornings commute. 60 miles at 50-80mph. Fabric snapped around for an hour, but didn't fray. At all.
The square I gave to the dog however, failed the 'Kirby Test'. (I gathered it up before he ingested any)
What is it? PolyU coated? U coated? Sil impreg, but only from one side?
None of the above?
