Some fleece materials used for certain clothing items are treated with flame retardants. As MN renovator suggests, the real way to see what you've potentially got a source of is to pick some up and test it with a torch in your fire pit outside. If it is not treated, I expect it burns about as quickly as a cotton ball. If it is treated, I expect the flame stops spreading when you take the flame source away.
