HI Linda,
Check this out:
http://www.fabrics.net/amyolefin.asp. Sounds like it can be made to feel like anything, and if they could get the low-melting point issue solved it would be a good thing.
Too bad. I looked into polyester and apparently the different in terms of usage for quilts etc would be the different melting points. Polyester resists ignition, but of course burns like the dickens when it does ignite.
And interesting tidbit from the same site: cotton has a very high burn rate, so mixed together cotton/poly's are damaging when burning than each individually. The cotton's high burn rate makes the poly ignite faster and the poly still melts. Not a pretty picture, huh?
Sorry this is so long. Somedays my curiousity gets the better of me!
