In my experience, yes.  In picking a fabric for making my own
changing bag I tried various materials.  As a first test I tried
my NightShot camcorder, aiming it straight at the sun through the
cloth I was testing.  I then tested a sample of the fabric by
wrapping up a piece of HIE in my dark room then laying it in the
sun.  

All of the black-rubber-coated fabrics I tried were IR safe.  

I ended up using rubber-coated polar fleece from Malden Mills.
It's not sold as light-tight fabric, but it has a very tough
layer of polyurethane rubber on one face, and black fleece on the
other, so that a rolled closure is quite light-tight.  (Besides
that I already had several spare yards of the fabric left over
from making winter cycling gear.)
