I have never had this problem. I use flannel, which is not prewashed. After making the rag quilt, I wash it in warm (not hot) water. I put it in the dryer with one TOWEL. About half-way through the drying cycle, I open the dryer and clean the lint filter then finish drying. You can do this sooner and more often if you want. The towel collects some, too, which is why I use it. Later, i just shake out the towel and wash it. This technique works very well for me.
