Anybody come up with a way to bond climashield to nylon?

Ray Jardine’s quilt kits use short bits of yarn that he pulls through the quilt and then knots each end.  I don’t know what you call them.

You can see them in photos at https://www.rayjardine.com/ray-way/Quilt-Kit/index.htm

Just scroll down to find the picture of the yellow 2-person quilt and you’ll see those black bits of yarn on the top.   (aside:  Ray has copyrighted all his photos, which is why I didn’t paste it in here.  Our club actually had to pay $hundreds because someone uploaded a copyrighted photo as a meme to our club’s Facebook page, and a copyright violation web crawler found it.)

That would probably do the trick.  I’ve done three Apex quilts myself and haven’t had much issue in this regard, but I see where it could bother some people.

I wonder if you could get creative with contact adhesive and “gluing” apex to one side of the fabric.  Doing both sides would probably be impossible, because you typically sew the synthetic quilt inside out along the edges, reverse it, then finish sewing the opening shut.  But, you’d probably have to compress the Apex so that enough of the filaments stick to the glue, with the potential downside that this process could decrease the overall loft of the Apex (and thus its warmth).

I see what you mean on the RJ quilt.

It would be a huge PIA, but on the inside layer of the quilt, on the inside, you could sew on a strip of fabric, maybe 1/4-1/2″ like a flap then loosely hand stitch the top part of the apex to that.  I dont care about the outside and would rather have it non stitched. Maybe I will try a section sometime.

Would it be worth the effort to talk to a textile store or a upholsterer to see what they might use or do?.

I have made a few of the climashield quilts and underquilts and haven’t bothered to stabilize them like Jardine showed in his early books.  I haven’t seen his quilt kit book, but from your description, he still suggests the yarn loops.

I seem to recall that this was one of the selling points of continuous sheets of climashield apex, that it was far more stable than what Ray was using in his kits at the time, and didn’t need to be stitched/baffled/looped in place.  Perhaps someone who has an Apex quilt from the likes of Enlightened Equipment could chime in and let us know if there is any fixment between the shell and the insulation.  But I think it is only stitched around the perimeter and the rest is left loose.  At least that is what it looks like to me…  https://enlightenedequipment.com/enigma-apex-custom/

I see that Ray’s page does not mention what insulation he is using in his kit currently.  Is he using climashield apex?

I have two EE climashield quilts and they are not stabilized. Only sewn around the perimeter.

I tried the Rayway method on my first MYOG quilt 12 years ago. ( Climashield xp, fixed footbox)

Even with big knots,  the stabilisation threads pulled through the lining fabric I’d used, so  I removed them.  It was stable enough without!

I still use that quilt in summer for some trips. It’s fine.

For a DIY quilt, if I were bothered about keeping the lining secured, I’d use 2 layers of insulation to get the rating I needed, and then stitch the liner to the inner layer of Climashield in appropriate places to keep it stable.  (Inner layer could be just 2oz , and then use whatever thickness for the outer layer).

Yeah that makes more sense.

I just looked it up in my copy of “Beyond Backpacking” (2000).  Ray says he used Primaloft or Polarguard 3d at the time.  If I recall correctly, the big difference with Apex is that the insulation is bonded to a scrim fabric that holds it all in place, which makes it so you don’t have to baffle or quilt it like the two insulations that Ray mentioned.
