[0012] A method for using a device for preparing a sun-proof casual shirt based on UPF protective fiber comprises the following steps: Step 1: The fabric required for the UPF protective fiber sun-proof casual shirt to be dyed is passed around the first guide roller and the upper end of the second guide roller close to the first guide roller and passed around the lower end of the pre-dyeing atomizing transfer tube. Subsequently, the fabric required for the UPF protective fiber sun-proof casual shirt to be dyed is passed around the upper end of another second guide roller and passed around the lower ends of two third guide rollers. The fabric required for the UPF protective fiber sun-proof casual shirt to be dyed is then passed around the upper ends of two fourth guide rollers and the lower end of the fifth guide roller. After that, the fabric required for the UPF protective fiber sun-proof casual shirt to be dyed passes between the sixth guide roller and the seventh guide roller and an appropriate amount of dye solution is introduced into the dyeing box. In step 2, the winding end of the fabric is pulled and gradually moved, so that the pre-dyeing atomizing rotating tube can be driven to rotate synchronously through the anti-slip convex strips. At the same time, the pre-dyeing pump body can introduce the dye liquid into the liquid outlet tube through the liquid inlet tube, and then the dye liquid is introduced into the pre-dyeing atomizing rotating tube through the liquid outlet guide hole and guided by the pre-dyeing atomizing rotating tube to the fabric wound around the outside thereof, so that the fabric can be pre-dyed, which makes it easier for the dye liquid to quickly and fully infiltrate the fabric in the later stage, thereby effectively improving the dyeing effect of the fabric; In step three, the dyeing-aiding motor can drive the dyeing-aiding fan blades and the half-face bevel gear to rotate, thereby introducing air into the first side tube and the second side tube, and then the air will be respectively guided into the first dyeing-aiding air duct and the second dyeing-aiding air duct and discharged from the first dyeing-aiding air duct and the second dyeing-aiding air duct. During this period, the half-face bevel gear will alternately engage with the two first bevel gears, thereby driving the dyeing-aiding rotating rod to rotate reciprocatingly, and then driving the third bevel gear to rotate reciprocatingly through the second bevel gear, further driving the first dyeing-aiding air duct and the first gear to rotate reciprocatingly, and driving the second dyeing-aiding air duct to rotate reciprocatingly through the second gear, thereby pushing the dye liquid to the upper and lower sides of the fabric synchronously, thereby further enabling the dye liquid to quickly and fully infiltrate the fabric, thereby further improving the dyeing effect of the fabric; In step 4, the electric push rod 1 can drive the lifting bracket 1 to move up or down, thereby driving the fourth guide roller and the fifth guide roller to move up or down synchronously. At the same time, the electric push rod 2 can synchronously drive the lifting bracket 2 to move up or down, thereby driving the fifth guide roller to move up or down a second time, thereby keeping the fabric in a tensioned state and allowing the dyed fabric to contact the dye solution for a second time to achieve gradient dyeing, thereby effectively improving the practicality and functionality of the preparation device. In step five, the return spring can continuously apply a downward force to the limiting ring, thereby continuously applying a downward force to the lifting bracket three through the lifting slide column, and then continuously applying a downward force to the seventh guide roller, further effectively squeezing the dyed fabric, thereby squeezing out the excess dye and returning it for use, avoiding the waste of dye and providing convenience for the subsequent drying of the fabric.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The warp and weft dense weaving method increases the UV shielding rate to over 98%, and the introduction of a hollow fiber structure enhances breathability. Combined with a three-dimensional tailoring process, it achieves a balance between sun protection and comfort. In addition, this product has been tested to have significant protection in the UVB / UVA bands, and the UPF value retention rate is ≥90% after 50 washes; 2. Through the setting and use of the pre-dyeing mechanism, the pre-dyeing atomizing rotating tube can be driven to rotate synchronously while the winding end of the traction fabric is gradually moved, and the dye liquid can be introduced into the pre-dyeing atomizing rotating tube and guided by the pre-dyeing atomizing rotating tube to the fabric wound around it, so that the fabric can be pre-dyed, which makes it easier for the dye liquid to quickly and fully infiltrate the fabric in the later stage, thereby effectively improving the dyeing effect of the fabric; 3. Through the setting and use of the dyeing auxiliary mechanism, air can be guided into the first dyeing auxiliary air duct and the second dyeing auxiliary air duct respectively and discharged from the first dyeing auxiliary air duct and the second dyeing auxiliary air duct, and can drive the first dyeing auxiliary air duct and the second dyeing auxiliary air duct to rotate synchronously, so as to push the dye liquid to the upper and lower sides of the fabric synchronously, thereby further enabling the dye liquid to quickly and fully infiltrate the fabric, thereby further improving the dyeing effect of the fabric; 4. The back-dyeing mechanism can drive the lifting bracket 1 to move up or down, thereby driving the fourth guide roller and the fifth guide roller to move up or down synchronously. At the same time, the lifting bracket 2 can be driven up or down synchronously, thereby driving the fifth guide roller to move up or down a second time. This can keep the fabric in a tensioned state and allow the dyed fabric to contact the dye solution for a second time to achieve gradual dyeing, thereby effectively improving the practicality and functionality of the preparation device. 5. By setting up and using the recovery mechanism, a downward force can be continuously applied to the limit collar, so that a downward force can be continuously applied to the lifting bracket three through the lifting slide column, and then a downward force can be continuously applied to the seventh guide roller, which can further effectively squeeze the dyed fabric, so that the excess dye liquid can be squeezed out and returned for use, avoiding the waste of dye liquid and providing convenience for the later drying of the fabric.

At the same time, the pre-dyeing pump body 52 can introduce the dye liquid into the liquid outlet tube 54 through the liquid inlet tube 53. Then the dye liquid is introduced into the pre-dyeing atomizing rotating tube 56 through the liquid outlet guide hole 55 and is guided by the pre-dyeing atomizing rotating tube 56 to the fabric wound around it, so that the fabric can be pre-dyed, which makes it easier for the dye liquid to quickly and fully infiltrate the fabric in the later stage, thereby effectively improving the dyeing effect of the fabric. In step three, the dyeing-aiding motor 64 can drive the dyeing-aiding fan blades 65 and the half-face bevel gear 66 to rotate, thereby introducing air into the first side tube 611 and the second side tube 612, and then the air will be respectively guided into the first dyeing-aiding air duct 613 and the second dyeing-aiding air duct 616 and discharged from the first dyeing-aiding air duct 613 and the second dyeing-aiding air duct 616. During this period, the half-face bevel gear 66 will alternately engage with the two first bevel gears 69, thereby driving the dyeing-aiding rotating rod 68 to rotate reciprocatingly, and then driving the third bevel gear 614 to rotate reciprocatingly through the second bevel gear 610, further driving the first dyeing-aiding air duct 613 and the first gear 615 to rotate reciprocatingly, and driving the second dyeing-aiding air duct 616 to rotate reciprocatingly through the second gear 617, thereby pushing the dye liquid to the upper and lower sides of the fabric synchronously, thereby further enabling the dye liquid to quickly and fully infiltrate the fabric, thereby further improving the dyeing effect of the fabric; In step 4, the electric push rod 1 72 can drive the lifting bracket 1 73 to move up or down, thereby driving the fourth guide roller 74 and the fifth guide roller 77 to move up or down synchronously. At the same time, the electric push rod 2 75 can synchronously drive the lifting bracket 2 76 to move up or down, thereby driving the fifth guide roller 77 to move up or down a second time, thereby keeping the fabric in a tensioned state and allowing the dyed fabric to contact the dye solution for a second time to achieve gradient dyeing, thereby effectively improving the practicality and functionality of the preparation device. In step five, the return spring 87 can continuously apply a downward force to the limiting ring 86, thereby continuously applying a downward force to the lifting bracket three 84 through the lifting slide column 83, and then continuously applying a downward force to the seventh guide roller 85, further effectively squeezing the dyed fabric, thereby squeezing out the excess dye and returning it for use, avoiding the waste of dye and providing convenience for the subsequent drying of the fabric.
