The invention relates to a treatment article and a method for treating a fabric by delivering one or more powdered benefit agents to a fabric in a tumble dryer and thus providing at least one fabric benefit such as sanitization and/or disinfection, whitening and/or stain removal to the fabric during the tumble drying process. The treatment article functions to dispense at least one powdered benefit agent to the fabric by means of a diffusing membrane having an average pore diameter such that the tumbling and/or heating action provided during the tumble drying process results in the delivery of an oxidant material in the form of a powdered benefit agent to the initially damp or wet fabric to provide at least one primary fabric benefit to the treated fabric. Optionally, a second and/or third benefit agent may additionally be included in the treatment article for simultaneous delivery of one or more additional fabric benefits. The invention also relates to a treatment kit employing a treatment article with instructions for the effective delivery of one or more fabric benefits to a fabric during a tumble drying process.
