What is claimed is: 1. A fabric treating apparatus comprising: a. a chamber for receiving a plurality of fabric articles to be treated; b. a motion provider configured to provide rotational motion to the chamber; c. an applicator configured to apply a fabric treatment fluid into the chamber; d. a programmable logic controller; e. at least one machine relay operatively associated with the controller and the motion provider; and f. a spray cycle relay operatively associated with the controller and the applicator; wherein the chamber exhibits a period of clockwise rotational motion, a period of counterclockwise rotational motion and a period of no motion which occurs at a period of transition between the two periods of rotational motion; wherein the controller and the relays are configured to make the motion provider and the applicator active at the same time such that the applicator applies the fabric treatment fluid into the chamber when and only when the chamber is in motion. 2. The apparatus of claim 1 further comprising a fabric load size sensor configured to determine the load size of the plurality of fabric articles received by the chamber such that the total volume of the fabric treatment fluid to be applied to the plurality of fabric articles can be determined. 3. The apparatus of claim 2 wherein the fabric load size sensor being selected from the group consisting of a weight scale, a load controller, operator input and combinations thereof. 4. The apparatus of claim 1 wherein the applicator is a pressure atomizer configured to convert the fabric treatment fluid into the form of a spray or a mist. 5. The apparatus of claim 1 wherein the applicator is a gas assist nozzle connected via a gas conduit to at least one gas supply. 6. The apparatus of claim 5 wherein the gas conduit operates at a pressure from about 5 psi to about 80 psi. 7. The apparatus of claim 6 wherein the gas conduit operates at a pressure from about 20 psi to about 30 psi. 8. The apparatus of claim 5 wherein the gas supply provides a gas selected from the group consisting of nitrogen, air, steam, and combinations thereof. 9. The apparatus of claim 1 wherein the fabric treatment fluid is applied in the form of a spray having a median droplet size of from about 5 microns to about 300 microns. 10. The apparatus of claim 1 wherein the fabric treatment fluid is applied in the form of a spray having a median droplet size of from about 5 microns to about 50 microns. 11. The apparatus according to claim 1 wherein the rotational motion is at less than about 1 G. 12. The apparatus according to claim 1 wherein the period of clockwise rotational motion lasts at least about 5 seconds, the period of counterclockwise rotational motion lasts at least about 5 seconds, and the period of no motion lasts at least about 1 second. 13. The apparatus according to claim 1 wherein the period of clockwise rotational motion lasts from about 5 seconds to about 20 seconds, the a period of counterclockwise rotational motion lasts from about 5 seconds to about 20 seconds, and the period of no motion lasts from about 1 second to about 5 seconds. 14. The apparatus according to claim 1 wherein the motion of the plurality of fabric articles results from motion of the chamber. 15. The apparatus according to claim 1 wherein the chamber is capable of countra-rotation.
