The feathers are just matted together. You need to put it in the dryer at low heat with a couple of tennis balls. The tennis balls bounce around hitting the blanket causing the matts to break up. Works great!Why do down comforters lose their fluff when you wash them in the washer?
If it is an all down comforter, the down becomes stuck together when moist. When I wash my down comforter, I dry it 3 times. I have found that if I don't, it later gets a ';musty'; odor, and that is because the down was still damp inside and started to mildew.





Dry your comforter several times after washing. Also buy a duvet cover for it so you don't need to wash it as often.Just wash the duvet.
Dry it with tennis SHOES. Balls don't have enought weight to fluff the down.
Washers hate fluff!!!!





The material down is broken down by the rigid wash cycle. This is a good answer isn't it?
If it is true down, it is goose or duck feathers. When you get the comforter wet, it is getting the feathers wet and weighted down.
