    Is 1.9 calendered DWR ok for a hammock ?

    I ordered some 1.9 for my DIY 11ft stretch side hammock and after it was all done I realized I had 1.9 calendered with DWR. It's spruce green 1.9 from diy gear supply. Can anyone tell me if this is an issue for breathability used as a hammock ? Is this a lost project......

    I searched and found lots of talk about ripstop from Joanne's being shiny calendered on one side but didn't find any feedback on this material actually used as a hammock.

    Thanks,

    Should be fine. May not be as breathable but DWR is not a waterproofing.

    Are you sure it is DWR? And if it is how much DWR was applied to the fabric? JoAnns ripstop is 1.9 and is perfect for hammock use. Plenty of folks here use it for their first DIY hammock.

    if you choose to not use it as a hammock, it should be great downproof material as it is calendared (correct me if I'm wrong, anybody!)

    my hammock gear weights total: 2430g (~86oz)
    Winter: total 2521 (~89oz)
    (see my profile for detailed weights)

    1.9 DWR is great for a hammock... I have 2...

    Calendared means downproof, which also means it will block a bit of the breeze... Breathability is good on this fabric...

    Go for it!

    At 200#, that is my preferred fabric weigh for a single layer hammock. It gives just a little. Lighter fabrics have too much stretch and heavier ones seem hard to me. I don't think that you will notice the calendaring in a hammock, one way or the other.

    Awesome, thanks all for the advice. I finished it an spent last night in the backyard in it. I'm pleasantly surprised its more comfortable than my old eno DN I ve used for last years. it's definitely flatter at 130" with a warbonnet type "whip". It fits well under the OMW tarp.

    I thought calendared meant "squished", I.e. the fabric was run between rollers to mash the fibers into ovals instead of circles (cross section), to make the weave tighter and less breathable. How can something be calendared "on one side"? I read about a guy who used calendared rip stop to make his own hot air balloons... But that was a while ago. I like the Jo Ann fabric, I made a hammock chair from some, it was easy to work with and feels strong.

    Two pieces of fabric are run between heated rollers at the same time resulting in the sides against the rollers being calendared and the fabric to fabric sides not being calendared....or something close to that.
