Zero Porosity Fabric

[Sorcerer]

On Henry Shire's Tarptent page he talks about a fabric called Zero Porosity Fabric from Aerodyne Research Corp. The link he has on his site is this:

I can't get that to work and was wondering if anybody knew where you could get enough to make a tarp? I made a sil-nylon tarp but the sewing is so hard to do because the fabric is so slick (and my sewing is crooked and just doesn't look the best).

Thanks for the info.

Looks like the IP is not resolving. I did a search for the fabrics and came up with a few hits:

I have found all kinds of information about the fabric by "Googling" it and had seen those links before. Unfortunately, none of those are links for actually buying the fabric.......I'm not planning on buying a $1700 parachute and making a tarp out of it. :datz

I guess I could always write Henry Shire to see where he gets it these days, but I hate bothering people who are trying to make money when I'm trying to make my own stuff.

You can get it at Noah Lamport, but it is silicon-coated ripstop nylon:

I still have trouble with sylnylon due to the slickness, and the fact that it will not hold a crease worth a darn. People have told me that pins will make leaks, but I find that if you use them in the seam wastage, it's ok since you are going to seal it anyway, and I don't think pinholes in the hems matter at all . Also, I gave up on nice neat 3/8ths inch seams, I go for 3/4 of an inch at least. It is easier to control the fabric and I don't see any difference in the water proof qualities. My current tarp has a big one inch wide french fell seam with four rows of stitches through it, right down the middle. No leaks, it's a year old, and I have spent several nights out in driving rains with it.

how old is this?

IIRC, Silnylon and Zero-porosity fabric are one and the same.

I coated some paper clips with diluted silicone, and they were good at holding folds in silnylon for sewing. However, they didn't last real long.

I bought some Scunci hairpins from Walgreens ($1.99) that are marked as having grooves on the inner surfaces and the package says "...grooves keep pins in place".

Haven't actually done silnylon sewing with them to see if this claim is true. But they seem to have a fair grip on the fabric.
