[0013] A water-saving cleaning method for polyester fabric production, using any one of the above-mentioned water-saving cleaning devices for polyester fabric production for cleaning, comprises the following steps:

[0014] Step 1: The polyester fabric is wound in an S shape on two rotating dehairing devices and transported forward. By making multiple dehairing brush rollers follow the rotating drum to revolve around the rotating axis, the dehairing brush rollers are also rotated, and the rotation speed of the rotating drum is inconsistent with the conveying speed of the polyester fabric, so as to roll brush the surfaces of both sides of the polyester fabric, and utilize the negative pressure adsorption of the negative pressure cover to promptly absorb the brushed fluff and short fibers, thereby preliminarily removing the fluff and short fibers;

[0015] Step 2: The polyester fabric passes around the first guide roller and is conveyed forward so that the polyester fabric enters the first water storage chamber of the water storage tank and is initially soaked in water;

[0016] Step 3: The polyester fabric passes through the water flow cavity between the top brushing assembly and the bottom brushing assembly and is transported forward. The top cleaning brush rollers and the bottom cleaning brush rollers are rotated to brush both sides of the polyester fabric. The downward flow of the water removes the brushed fluff and short fibers in time to clean the polyester fabric once.

[0017] Step 4: The polyester fabric passes through a plurality of squeezing rollers and a pressing plate and is conveyed forward. The plurality of squeezing rollers are rotated to initially squeeze out the water absorbed by the polyester fabric after passing through the primary cleaning device.

[0018] Step 5: The polyester fabric passes through one of the second guide devices, two rubbing devices and another second guide device in turn and is transported forward and immersed in the water in the cleaning water tank. The upper rubbing roller is driven up and down by the second linear drive member, and the upper rubbing rollers of the two rubbing devices move in opposite directions to rub the surfaces of both sides of the polyester fabric and achieve a secondary cleaning effect.

[0019] From the above description, it can be seen that the water-saving cleaning equipment and method for polyester fabric production provided by the present invention have the following beneficial effects:

[0020] 1. By setting up a rotary depilatory device, the easily removable fluff or short fibers on the surface of the polyester fabric can be removed before it enters the water;

[0021] Second, the polyester fabric can be cleaned once and twice in sequence through the primary cleaning device and the secondary cleaning device, thereby removing the fluff or short fibers on the surface of the polyester fabric that are difficult to remove;

[0022] 3. By providing an inclined water flow chamber between the top brush assembly and the bottom brush assembly of the first cleaning device, and cooperating with the provision of the first filter water supply assembly, it is effectively ensured that the water in the water flow chamber is flowing and clean. By filtering and purifying the water in the first water storage chamber and recycling it, it is beneficial to save water resources. In addition, the water in the water flow chamber will flow from its high side to its low side, and the polyester fabric is transported from the low side to the high side of the water flow chamber. This ensures that the polyester fabric is always exposed to cleaner water during the forward transportation and cleaning process, thereby effectively ensuring the overall cleaning effect.

[0023] Fourth, by providing the first guide device, the polyester fabric can be guided into the first water storage chamber before entering the first cleaning device, thereby allowing the polyester fabric to be immersed in water first. At the same time, while the first cleaning device is cleaning the polyester fabric, part of the water will flow directly along the surface of the polyester fabric to the bottom of the first water storage chamber without flowing out of the water tank;

[0024] 5. Through the setting of the lifting drive assembly, when cleaning is required, the top brush assembly can be driven to rise by the lifting drive assembly to separate the fixed brush assembly from the bottom brush assembly, thereby facilitating the polyester fabric to pass through the cleaning device once. After passing through, the bottom brush assembly is driven to descend by the lifting drive assembly. BRIEF DESCRIPTION OF THE DRAWINGS
