Abstract

The present invention relates to methods of delivering one or more volatile materials, during the operation of a drying apparatus, to a fabric article. The present invention also relates to fabric treatment compositions comprising one or more volatile materials.

C. or higher, and then returned to a second operating temperature of less than about 70°

C.

10. ) The method of claim 9 wherein said application occurs after said second operating temperature of less than about 70°

C. is reached but before a third operating temperature of about 20°

C. is reached.

11. ) The method of claim 8 wherein said application occurs after a second operating temperature of less than about 60°
