Technical Field

[0001] The utility model belongs to the technical field of textiles, and in particular relates to a one-bath dyeing device for nylon-cotton knitted fabrics. Background Art

[0002] With the significant improvement of people's living standards, the aesthetic and quality requirements for clothing are increasing, which has greatly promoted the vigorous development of the textile industry. Today's consumers are no longer limited to traditional single-color clothing, but instead pursue colorful, novel and unique clothing designs. This trend has injected strong development momentum into the dyeing equipment market.

[0003] However, most existing dyeing technologies for nylon-cotton knitted fabrics use a single dyeing process, which often results in insufficient dyeing of the fabric, making it difficult to achieve the desired color saturation and uniformity, indirectly affecting the final texture and aesthetics of the finished product. Although some people have proposed to make up for this deficiency by adding secondary dyeing, this will not only cause repeated consumption of dye resources, but also significantly increase production costs, including more manpower input and material consumption.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0023] The stirring mechanism includes a support plate 23, a stirring motor 24 is provided on the support plate 23, a rotating rod 25 is provided on one side of the stirring motor 24, the rotating rod 25 is arranged in the dyeing chamber 2, and a stirring member 26 is provided on the rotating rod 25. The stirring member 26 includes a first stirring member 261 and a second stirring member 262, the first stirring member 261 and the second stirring member 262 are both in an inverted L-shaped structure, and the length of the first stirring member 261 is greater than the length of the second stirring member 262. The stirring member 26 is provided to avoid the precipitation of the dye solution and affect the dyeing effect.

[0024] The water filtering mechanism comprises a first pressing roller 27 and a second pressing roller 28 which are arranged opposite to each other. A lifting assembly 29 is arranged on both sides of the first pressing roller 27. The lifting assembly 29 is used to drive the first pressing roller 27 to move up and down. The lifting assembly 29 comprises a fixed block 294. A lifting motor 291 is arranged on the fixed block 294. A lifting rod 292 is arranged on one side of the lifting motor 291. A connecting block 293 is arranged at one end of the lifting rod 292. The connecting block 293 is fixedly connected to the first pressing roller 27. It should be noted that both sides of the first pressing roller 27 are arranged in the through hole 6 of the side wall of the dyeing chamber 2. The through hole 6 has a certain length, that is, there is a certain height space to ensure that the lifting assembly 29 drives the first pressing roller 27 to move up and down.

[0025] An air outlet 31 is provided in the drying box 3, a hot air pipe 32 is provided on the air outlet 31, a hot air blower 33 is provided at one end of the hot air pipe 32, and the fabric 4 is dried after dyeing through the drying box 3. A fifth pipe 22 is provided between the dyeing chamber 2 and the dye box 5, and a fifth circulation pump 221 is provided on the fifth pipe 22, which is used to pass the dye liquid in the dye box 5 into the dyeing chamber 2. A sixth pipe 51 is provided on one side of the dye box 5, and a valve 511 is provided on the sixth pipe 51, which is used to input the dye liquid into the dye box 5.

[0026] Here’s how it works:

[0027] First, open the valve 511, input dye solution into the dye box 5 through the sixth pipe 51, and then close the valve 511. Then, turn on the first circulation pump 131 on the first pipe 13, the second circulation pump 141 on the second pipe 14, and the fifth circulation pump 221 on the fifth pipe 22, spray the dye solution in the dye box 5 into the spray dyeing chamber 1 through the first nozzle 11 and the second nozzle 12, and introduce a certain amount of dye solution into the dyeing chamber 2. At the same time, turn on the stirring motor 24 to drive the stirring member 26.

[0028] Then, the fabric 4 is transported in the spray-dyeing chamber 1 in a Z shape, and the upper and lower surfaces of the fabric 4 are spray-dyed, that is, the first dyeing is performed, and then it is transported in the dyeing chamber 2 in a U shape, and the fabric 4 is dyed for the second time. The cotton-nylon knitted fabric 4 is dyed twice, which deepens the coloring effect, improves the color saturation and uniformity of the finished product, and makes the dyeing quality higher. At the same time, the third circulation pump 151 on the third pipeline 15 and the fourth circulation pump 211 on the fourth pipeline 21 are turned on to recycle the dyes in the spray-dyeing chamber 1 and the dyeing chamber 2, thereby reducing dye waste and reducing production costs.

[0029] After the fabric 4 is dyed for the second time, the excess filtrate on the fabric 4 is filtered out by the water filter mechanism. The specific process of the filter press is to adjust the lifting assembly 29 according to the thickness of the fabric 4 so that the fabric 4 can be squeezed and filtered between the first pressing roller 27 and the second pressing roller 28. Finally, the fabric 4 is transported in a U-shaped manner into the drying box 3, and the fabric 4 is dried by the hot air blower 33, the hot air pipe 32 and the air outlet 31.
