Abstract: 1. A continuous and combiningly operable breadth expansion and vibration enhanced spray dyeing machine, which comprises: one or a plurality of connectable processing tubs, which has a wide cross section of passage therein for a fabric to proceed dyeing and other processing operation in a continuous or unified way; an inlet passage, which is proved on the upper end of the upstream side wall of said processing tub; an outlet passage, which is provided on the upper end of the downstream side wall of said processing tub; a dynamical cloth dragging wheel, which is provided at each of said inlet and outlet passages; a cloth collecting tub, which is provided below said inlet passage in the upstream sector of the passage in said processing tub; a cloth guide tube, which is formed with a slant angle between said cloth collecting tub and said outlet passage in the downstream sector of said processing tub, so that the downstream end of said cloth guide tub is higher than its upstream end; on or a plurality of dye nozzles, which are formed on the upper side walls of said cloth guide tube and connected with a dye pump via a pipe for the dye or treating liquid to be guided in and ejected out so that the dye or treating liquid ejected toward said fabric can be sprayed into atomized particles and distributed on a large area of said fabric; one or a plurality of sector separated air guiding nozzles, which are formed along the passage on the cross section of the lower side walls of said cloth guide tube so that the upstream air guiding nozzles and the downstream air guiding nozzles are separated with a distance; a reflective action base, which is formed in the downstream direction of each of said air guiding nozzles and connected with a blast machine via a pipe for the pressurized gas to be guided into said air guiding nozzles and ejected out; wherein under the action of said reflective action base, the ejected high speed air flow can flow along the upper surface of said reflective action base and proceed toward the upstream direction under said fabric so that the pressure below said fabric is lower due to a higher speed of air flow and the pressure above is higher due to a slower air flow, and the upper and lower air flows would interact to ensure that said fabric can pass through said cloth guide tube in a fully breadth expanded way and have a periodic violent vibration, said fabric is also continuously pushed toward the mainstream area of the high speed air flow due to both the pressure difference and the gravity so as to have a close contact with the high speed air flow and to increase the energy conversion rate so that the dye can obtain the most energy from the air flow for penetrating into the fabric texture; therefore, in the process of dyeing, in addition to obtaining the small amount high concentration, high efficiency, low energy consumption, low bathing ratio and low pollution dyeing, the fabric can also achieve the debounding and relaxing effects via the periodic violet vibration, while at the same time, the impurities on the fiber can be so efficiently removed that processing operations such as desizing, scouring, bleaching, reduction, enzyme treating, soaping, washing can be quickly finished in order to realize the goal of a high efficiency, low tension, low energy consumption, low bathing ratio and environment-preserving continuous dyeing and processing operations within an extremely short period of time. 2. The spray dyeing machine as claimed in claim 1, which further comprises a dragging type gas liquid circulation guide plate and a separation type gas liquid circulation passage provided between of said cloth guide tube and said cloth collecting tub; wherein said gas liquid circulation guide plate is formed by extending said reflective action base and forms an arc circulation, the downstream sector of said gas liquid circulation guide plate forms one or a plurality of liquid confluent pipes in different way, and an passage is formed between said liquid confluent pipes so that liquid can pass through said confluent pipes along said gas liquid circulation guide plate due to the dragging of said dragging type gas liquid circulation guide plate, the pressure difference, and the potential and be guided into the lower side walls of said processing tub so that the air flow under said fabric can circulate and pass through said net under said cloth collecting tub and be redirected into said blast machine via said air circulation passage, and therefore a gas liquid separation circulation is formed within said processing tub. 3. The spray dyeing machine as claimed in claim 1, which further comprises a spray nozzle device on said air distributing passage, said device comprising a passage pipe provided with one or a plurality of nozzles, wherein the other end of said passage pipe can connect to a dye transmission pipe, a pressurized pump or water tank, and a steam transmission pipe via pipes, and control valve is provided on each of said pipes so that the dye, water, or steam can be guided to the nozzle on said air distributing passage according to the manufacturing procedure for ejection in such a manner that the ejected liquid or gas can be mixed with the air flow and said air guiding nozzle can eject a high speed air flow containing a large amount of dye liquid, water, or steam. 4. The spray dyeing machine as claimed in claim 1, which further comprises a cloth wiggling machine provided under said dynamical cloth dragging wheel on the upstream passage of said processing tub; said cloth wiggling machine comprising a wiggling plate, said transmission axis on one end of said wiggling plate, a driving rod, a driver; wherein said wiggling plate can be fixed on the left and right side walls by said transmission axis, with one end extending outside the tub wall and connecting with said driver, so that said wiggling plate can perform longitudinal reciprocating motion and said fabric passing said wiggling plate falls into said cloth collecting tub with an expected folding effect. 5. The spray dyeing machine as claimed in claim 1, which further comprises an air inlet and an exhaust outlet provided on the blast machine inlet passage; an exhaust hot air outlet and nitrogen (inert gas) inlet provided on the side walls of said processing tub; and treating liquid recycling outlet at the bottom of said processing tub; wherein a control valve is provided on each of said inlets and outlets, and the air supply or convection in said processing tub can be arbitrarily controlled according to the manufacturing procedure. 6. The spray dyeing machine as claimed in claim 1, which further comprises a heat exchanger, a filter connecting to said dye transmission or circulation passage and said air transmission or circulation passage, respectively, to form a passage. 7. The spray dyeing machine as claimed in claim 1, which further comprises a water nozzle provided in said processing tub, wherein said water nozzle is provided at the corner that is easy to be polluted and connects to a high pressure pump via a pipe so that the water can be guided into said nozzle for ejecting toward the polluted wall when each dyeing process is completed.
