"Treated", in my dictionary, means "waterproofed". Usually that means polyurethane (think of an average tent fly) or silicone-treated nylon (silnylon, or just "sil".) Depending on the usage, waterproof fabrics may end up trapping moisture in the insulation inside. If you're using down, well, that's not good. Used against the body, they may make the hanger clammy by keeping insensible perspiration against you. The threads here covering vapor barriers goes into a lot of detail.
One other thing about treated fabrics I just remembered: it can make a quilt hard to fold or stuff unless you've got places where the air inside the quilt can escape.
