If the laundry is being done by the facility, it is most likely either in their own industrial machines or they send it out to be done at a commercial facility. This might especially be the case with anything they consider bedding.
From my experience with a family member's belongings, if there is anything you don't want to risk being washed in very hot water and dried at very hot temperatures, she should probably not take it.
As an aside, no other valuables (like jewelry) should move with her if possible.
