I've only used Hobbs 80 cotton 20 poly batting and have washed it without any problems.
Wash isn't the correct term because you just soak the batting in your washing machine, DO NOT AGITATE, then turn to the spin cycle. I don't put the batting into the dryer, I just lay it on the floor or over the dining room table to dry complety. Putting a plastic sheet or tablecloth down first is a good idea.
