Abstract
A method of treating fabric in a rotary clothes dryer is provided in which a substantially non-ionic liquid fabric treating composition is applied to a non-woven substrate, dried on the substrate to form a water-activated dryer sheet and then transferred during the course of a drying cycle from the water-activated dryer sheet to damp clothing within a clothes dryer as a result of contact of the composition with water contained within the damp clothing.
Claims15
A method of treating fabric in a clothes dryer, comprising:
- (a) providing a non-woven substrate;
- (b) providing a substantially non-ionic liquid fabric treating composition having at least one active ingredient;
- (c) applying the fabric treating composition, in liquid form, to the non-woven substrate;
- (d) following step (c), drying the fabric treating composition on the substrate to form a water-activated dryer sheet;
- (e) placing damp clothing containing water into the interior of the clothes dryer;
- (f) placing the water-activated dryer sheet into the interior of the clothes dryer with the damp clothing, the damp clothing and the water-activated dryer sheet not being enclosed together within a bag or other container during the course of a drying cycle while the damp clothing is being dried;
- and
- (g) transferring an effective amount of the at least one active ingredient of the fabric treating composition from the water-activated dryer sheet to the damp clothing during the course of a drying cycle as a result of contact of the fabric treating composition with the water contained within the damp clothing.

- and
- (g) transferring an effective amount of the at least one active ingredient of the fabric treating composition from the water-activated dryer sheet to the damp clothing during an initial stage of a drying cycle, beginning when the damp clothing has its greatest water content and prior to heating the damp clothing to a temperature necessary to remove water from the damp clothing, as a result of contact of the fabric treating composition with the water contained within the damp.

A method of treating fabric in a clothes dryer, comprising:
- (a) providing a non-woven substrate;
- (b) providing a substantially non-ionic liquid fabric treating composition including at least one active ingredient comprising a wax-based dispersion containing wax crystals and an emulsifier;
- (c) applying the fabric treating composition, in liquid form, to the non-woven substrate, the emulsifier being effective to assist in maintaining the wax crystals suspended in the wax-based dispersion so that they are substantially evenly distributed on the substrate;
- (d) following step (c), drying the fabric treating composition on the substrate to form a water-activated dryer sheet;
- (e) placing damp clothing containing water into the interior of the clothes dryer;
- (f) placing the water-activated dryer sheet into the interior of the clothes dryer with the damp clothing, the damp clothing and the dryer sheet not being enclosed together within a bag or other container during the course of a drying cycle while the damp clothing is being dried;
- and
- (g) transferring an effective amount of the at least one active ingredient of the fabric treating composition from the water-activated dryer sheet to the damp clothing during the course of a drying cycle as a result of contact of the fabric treating composition with the water contained within the damp clothing.
