Robic fabric source?

I’d be interested to see the CFM of this 7D Robic…I’m guessing its not that great.

You cannot successfully silicone treat other fabrics that have the more traditional DWR’s on them (C6, C8, etc).  The silicone doesn’t bond to these.  Silicone will bond to silicone though.

I silicone treated some fabric that i thought wasn’t treated with a DWR, and when i sent it to Richard Nisley to have it tested for CFM and HH levels, it seems that the silicone blasted right off during the HH testing.  Richard saw that the fabric had a pre-existing, high quality DWR.

Known: silicone polymer and fluorocarbon DWR are just not compatible.
It’s a problem.

I have some 39gsm schoeler fabric I could send Richard for testing.

It’s there lightest fabric they make with the schoeller treatment.

From Schoeller:

NanoSphere^® is based on future-oriented C6 fluorochemicals (i.e. molecule chains consisting of 6 carbon atoms and 13 fluorine atoms). Even with highly-sensitive measurement methods, which detect impurities as small as 25 ppb (parts per billion), neither PFOA nor PFOS was found. The NanoSphere^® finish is therefore considered PFOA- and PFOS-free. It combines modern functionality and the ecological requirements which will apply to fluorochemicals in the future. The possible secondary components of a C6-chemical (for example PFHxA = perfluorohexanoicacid) do have a positive ecological profile.

PFOA- and PFOS-free  A development to be greatly desired!

Thanks Woubier.

Thank you Woubeir for the correction.  I edited my earlier post to take out the erroneous info.

I have no experience with Nanosphere DWR, but i’ve heard that it’s more durable than most other DWR’s.  If that is the case, how do they accomplish that with a C6 type finish?
