Hi All...

New and my first post (have been a long time reader great site)

I was in a fabric store picking up some ripstop today and the guy asked if I was interested in Gore-tex (obviously). I can’t say I was too prepared or done enough research on Gore-tex to be able to identify the type (2 layer 3 layer) or if it was indeed gore-tex at all. So I grabbed a few yards to dangle with, but not knowing has got the better of me and I want to know what it is..lol

Here is what I have... if anyone would be willing to help identify it for me, I'd be quite thankful...lol

Measurements and weight might help.

I have some 2.5 layer eVent - the inside surface has sort of a grid that's maybe 1/32 inch in each direction

I have some 2 layer eVent - inside surface is uniform white color

That's probably applicable to Gore-Tex

If you had 3 layer, it would have a seperate inner fabric that's not attached

Thanks Jerry, it makes sense. It also has the tiny square pattern on the bottom and it holds water just fine so whatever it is - it works.

Sorry Eugene - not around me ole scale...

No, that's not correct.

2-layer is outer nylon fabric + membrane

2.5-layer is outer nylon fabric + membrane + inner protective layer

3-layer is outer nylon fabric + membrane + inner nylon layer

The clothing manufacturer adds an extra layer(most of the time some kind of net) when they sew stuff with 2-layer fabrics to protect the membrane from wear from the inside.

Since Gore and eVent laminate uses a Teflon, they will be white and slippery on exposed, two layer versions. Other brand laminates/coatings often use a urethane
which is a bit more rubbery and stickier.

Goretex has become a generic name at some fabric stores, so ask if you can see the
tags.
