Description

Technical Field

[0001] The present invention relates to the technical field of textile dyeing, and particularly to a two-way dyeing device for fabric processing and a dyeing method thereof. Background Art

[0002] Textile fabrics can be divided into two categories: weft knitted fabrics and warp knitted fabrics according to the weaving method. Weft knitted fabrics are often made of low-elastic polyester filaments, profiled polyester filaments, nylon filaments, cotton yarns, wool yarns, etc., and are knitted on various weft knitting machines using plain stitch, modified plain stitch, rib plain stitch, double rib plain stitch, jacquard stitch, loop stitch, etc. Fabric dyeing means attaching color to the fabric, also known as coloring, which refers to using chemical or physical methods to affect the substance itself and make it colored. Under the condition permitted by technology, through dyeing, objects can present various colors required by people, decorating life with colorful colors. The method of dyeing has existed since ancient times and has been continuously developed.

[0003] During the fabric dyeing process, the generated wastewater is collected through a collection tank. The dyes in the wastewater have not been completely adsorbed onto the fibers, so it contains a large amount of dye components. Subsequently, a membrane is used to filter it to separate the dye components in the wastewater from other impurities for subsequent recycling of the dyes.

[0004] Deficiencies of the prior art: Since the membrane filtration technology relies on the pores on the membrane surface for material separation, as the usage time increases, the membrane surface is easily contaminated or blocked by substances such as suspended particles, oils, and dyes in the wastewater. This will reduce the filtration efficiency of the membrane and also increase the efficiency of replacing the membrane. Summary of the Invention

In the present invention, the acrylic transparent plate can intercept the dyestuff sprayed by the nozzle to prevent some dyestuff from splashing onto the ground or the staff. Furthermore, after using the device, the hydraulic cylinder is driven to drive the cleaning brush to clean up and down on the inner surface of the acrylic transparent plate, thereby cleaning the dyestuff remaining on the inner surface of the acrylic transparent plate, effectively intercepting the splashing dyestuff, reducing dyestuff waste, and at the same time avoiding the influence of the dyestuff on the ground and the staff. Moreover, the dyestuff on the inner surface of the acrylic transparent plate is automatically cleaned, reducing the need for manual cleaning and improving work efficiency; 3.

At this time, the limiting block will be aligned with the limiting hole formed on the surface of the rack and matching the inserting rod, and the inserting rod is inserted into the aligned limiting hole to limit and fix the turning roller A. It is beneficial for the fabric to be fully stretched after passing between the turning roller A and the turning roller B, avoiding the phenomenon that the fabric folds with the shaking of the dyestuff in the collection pool.

At this time, the limit block 603 will be aligned with the limit hole on the surface of the rack 601 that matches the plug rod 604, and the plug rod 604 is inserted into the aligned limit hole to limit and fix the turning roller A8. This is beneficial for the fabric to be fully unfolded after passing between the turning roller A8 and the turning roller B9, avoiding the phenomenon of folding as the dye shakes in the collection tank 3. Then, the water pump 1 is driven to pump the filtered dye into the nozzle 502, so that the nozzle 502 sprays the dye onto the fabric. At this time, the acrylic transparent plate 507 can intercept the dye sprayed by the nozzle 502 to prevent some dye from splashing onto the ground or the staff, effectively intercepting the splashing dye and reducing dye waste. The fiber network structure on the cellulose filter paper 204 can physically prevent the impurity particles in the dye with larger sizes from passing through, similar to the function of a sieve. The cellulose molecule surface has a certain hydrophilicity and can adsorb some water-soluble small molecule impurities. Subsequently, when the dye liquid passes through the activated carbon 205, the dye molecules and impurities will be adsorbed by the pores of the activated carbon 205 to achieve the effect of removing impurities. Then, after using the device, the hydraulic cylinder 505 is driven to drive the cleaning brush 504 to clean up and down on the inner surface of the acrylic transparent plate 507, thereby cleaning the residual dye on the inner surface of the acrylic transparent plate 507. Then, the electric slide rail 201 and the hydraulic rod A202 are driven to adjust the cellulose filter paper 204 and the activated carbon 205 in the limit box 203 onto the collection box 207, and the staff places the used cellulose filter paper 204 and activated carbon 205 into the collection box 207 for later unified treatment, improving the removal of insoluble impurities and particles in the dye solution, ensuring the purity efficiency of the dye solution, and also improving the efficiency of replacing the cellulose filter paper 204 and the activated carbon 205.
