If you put the no sew fleece in the microwave, would it melt? I'm presuming it's not made from a natural fiber, but would it be completely a bad idea?

I wanted to make some rice bags, and I thought to make them extra cozy I could make them from fleece since I can't find flannel I like. Then it occured to me that microwaving it might get...well...sticky. (Doh, bad pun...)

Anybody have a clue or experience?

I could microwave a swatch to test, but I'm not really keen on having to clean melted goop out of my machine if someone else has the answer already. :)
