Inside the filter box 206, the dye is filtered through a plurality of filter holes 210 on the moving table 209 to remove impurities. The filtered dye is evenly sprayed on the cotton fibers through the spray head 211 at the bottom to achieve dredging. If the dye height in the working box 1 is greater than the height of the cotton fibers, immersion dyeing can be performed. If not, dredging can be performed. It can be processed according to the use requirements and is more adaptable. The first winding roller 301 and the second winding roller 304 in the extension component 3 move synchronously. The fiber is moved back and forth between the two rollers to be fully extended. The heat emitted by the heating wire 308 dries the fiber to prepare for subsequent extrusion and drying. The extended fiber will pass through the extrusion component 4, in which the extrusion plates 405 are close to each other under the action of the coil spring 404 to squeeze out the excess dye in the fiber. The rubber strip 406 prevents the dye from overflowing from the connecting window 102 to ensure that the dye is fully recycled. The design of the circulation component 2 allows the dye to be recycled, reducing the consumption of the dye and the generation of waste dye liquid, and improving production efficiency. Through the synergistic effect of the extension component 3 and the extrusion component 4, the fiber can be evenly extended during the processing process, ensuring the uniformity of dyeing and avoiding color difference and color spots. The equipment can flexibly select immersion dyeing or shower dyeing according to the dye height and the specific needs of the fiber to adapt to different production needs. The entire bleaching and dyeing process can be completed automatically, improving the overall production efficiency.
