  • Fabric care bag
    Patent number: 5789368
    Abstract: A fabric cleaning/refreshment process is conducted in a hot air clothes dryer using a vapor-releasing containment bag. The bag is constructed using heat resistant polymers, such as nylon, to avoid unanticipated hot spots in the dryer. The bag retains its integrity and can be re-used in subsequent dry cleaning operations. Vapor is vented from the bag during use, thereby minimizing wrinkling in the clothes being cleaned and removing malodors therefrom.
