Wrinkle reducing and deodorizing dryer sheet and methods of making and using
Provided are wrinkle reducing and deodorizing dryer sheets and methods of making and using the dryer sheets. In one form of the dryer sheet, the wrinkle reducing and deodorizing dryer sheet includes an absorbent wet substrate in sheet form with a polyvinyl alcohol sheet adhered to one surface of the substrate. In another form the PVA sheet is added separately from that of the absorbent wet substrate sheet. The PVA sheet is preferably in the form of an uncoated non-woven of a thickness of 8 mil or less. The wet impregnated sheet contains a solution of quaternary ammonium salts of different water solubility. The method for using, the wrinkle reducing and deodorizing dryer sheet is added to a rotary dryer with a load of wet or dried garments to reduce wrinkling in the garments during the drying process, reduce static cling and refresh the treated clothing.
