Abstract
A vapor-venting containment bag having at least three flexible side walls and a VVE rating of at least about 40 and less than about 90, as measured in the Vapor Venting Evaluation Test. When the bag is in its closed configuration a three dimensional interior void space is formed whereby the bag resists collapsing. Also, a fabric cleaning and refreshment process that is conducted in a hot air clothes dryer using the vapor-releasing containment bag. The bag is constructed using heat resistant polymers, such as nylon. 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.
