Frances,
Since most of my quilts are wall hangings, I never wash the batting or the quilt. But, here is what I can tell you about it. Since I do not have the space to sandwich and baste a large quilt, I sent it off to a friend to baste on her long arm. When it came back, it had "fuzzies" all over. I used my sticky roller to remove said fuzzies, and realized it just kept pulling out more. It was bearding. Since I had paid a premium for it, I figured it had to be good, and placed the blame on a "cheap" basting thread. So, when there were areas of my quilt that I needed to do some extra basting, I used a good needle and Masterpiece thread. It bearded!! But, I did not get bearding when I was machine quilting it. And, it quilted beautifully (4th of July close up in profile). So, I'm guessing you just have to find the right needle AND thread for this batting. I suggest getting a small piece first and playing with it, before investing in a larger size.
