A fabric treatment composition is provided. The fabric treatment composition includes a fabric treatment agent and a carrier component for containing the fabric treatment agent in a solid form during operation conditions in a dryer. The fabric treatment composition is constructed for transferring the composition to wet fabric as a result of solubilizing the fabric treatment composition by contacting the fabric treatment composition with the wet fabric during a drying operation in a dryer. A method for treating fabric is provided.

We claim: 1. A solid cast block fabric treatment composition comprising: (a) fabric treatment agent comprising a fabric softener component comprising ester quaternary ammonium compound; and (b) carrier component for containing the fabric treatment agent in a solid form during operating conditions in a dryer, the carrier component comprising alkylamide having the following formula: wherein R3 is an alkyl group containing between about 6 and about 24 carbon atoms, and R4 and R5 can be the same or different and each are hydrogen or an alkyl group containing 1 to about 24 carbon atoms, wherein the fabric treatment composition transfers to wet fabric as a result of solubilizing the fabric treatment composition by contacting the fabric treatment composition with the wet fabric during a drying operation in a dryer, and wherein the composition is provided in a form constructed to provide release of an effective amount of the fabric treatment agent during the drying operation. 2. A fabric treatment composition according to claim 1, wherein the fabric treatment agent further comprises at least one of anti-wrinkling agents, dye transfer inhibition/color protection agents, odor removal/odor capturing agents, soil shielding/soil releasing agents, ultraviolet light protection agents, fragrances, sanitizing agents, disinfecting agents, water repellency agents, insect repellency agents, anti-pilling agents, souring agents, mildew removing agents, allergicide agents, and mixtures thereof. 3. A fabric treatment composition according to claim 1, wherein the solid cast block composition has a size of at least about 5 grams. 4. A fabric treatment composition according to claim 1, wherein the solid cast block is constructed for attachment to an inside surface of a dryer. 5. A fabric treatment composition according to claim 1, wherein the composition has a melting temperature above 90�� C. 6. A fabric treatment composition according to claim 1, wherein cotton terry cloth towels, when subjected to at least 10 drying cycles in the presence of the fabric treatment composition, exhibit a whiteness retention of at least 90%. 7. A fabric treatment composition according to claim 1, wherein fabric dried in the presence of the fabric treatment composition exhibit at least a 50% static reduction compared with the fabric dried outside of the presence of the fabric treatment composition. 8. A fabric treatment composition according to claim 1, wherein the composition is constructed to provide substantially no transfer of the fabric treatment agent once fabric in the dryer has dried. 9. A method for treating fabric in a dryer, the method comprising: (a) allowing fabric containing free water to contact a solid cast block fabric treatment composition inside a dryer during a drying operation, wherein the fabric treatment composition comprises: (i) a fabric treatment agent comprising a fabric softener component comprising ester quaternary ammonium compound; and (ii) carrier component for containing the fabric treatment agent in a solid form during operation conditions in a dryer, the carrier component comprising a alkylamide having the following formula: wherein R3 is an alkyl group containing between about 6 and about 24 carbon atoms, and R4 and R5 can be the same or different and each are hydrogen or an alkyl group containing 1 to about 24 carbon atoms; and (b) transferring the fabric treatment agent from the fabric treatment composition to the fabric as a result of solubilizing the fabric treatment agent with the free water in the fabric, and wherein the composition is provided in a form constructed to provide release of an effective amount of the fabric treatment agent during the drying operation. 10. A method according to claim 9, wherein the step of transferring the fabric treatment composition substantially ends when the fabric dries sufficiently to lose the free water. 11. A method according to claim 9, wherein the step of transferring the fabric treatment composition comprises transferring the fabric treatment composition at a rate that decreases as the fabric dries during the drying operation. 12. A method according to claim 9, wherein the solid cast block composition has a size of at least about 5 grams. 13. A method according to claim 9, wherein the solid cast block composition is constructed for attachment to an inside surface of a dryer. 14. A method according to claim 9, wherein the composition has a melting temperature above 90�� C. 15. A method according to claim 9, wherein cotton terry cloth towels, when subjected to at least 10 drying cycles in the presence of the fabric treatment composition, exhibit a whiteness retention of at least 90%. 16. A method according to claim 9, wherein fabric dried in the presence of the fabric treatment composition exhibit at least a 50% static reduction compared with the fabric dried outside of the presence of the fabric treatment composition.
