[0001] The present invention relates to the technical field of continuous rapid steaming salt-free reactive dyeing, and particularly to a continuous rapid steaming salt-free reactive dyeing method. Background Art

[0002] In the prior art, the existing continuous rapid steaming salt-free reactive dyeing method has a relatively wide range of applications in life. During the dyeing process of the common continuous rapid steaming salt-free reactive dyeing method, wastewater is inevitably generated. When treating the generated wastewater, most of them do not have relatively good treatment measures. After the continuous rapid steaming salt-free reactive dyeing is completed, most of the generated wastewater is directly discharged externally. Most of the directly discharged wastewater is polluting. When the wastewater is directly discharged, it is very easy to cause environmental pollution. And when the wastewater is directly discharged, if continuous rapid steaming salt-free reactive dyeing treatment is carried out again, water source needs to be added again, resulting in the continuous rapid steaming salt-free reactive dyeing treatment not having good water-saving and energy-saving measures, seriously affecting the environmental protection, water-saving and energy-saving measures of the continuous rapid steaming salt-free reactive dyeing treatment. Summary of the Invention

[0003] The purpose of the present invention is to solve the disadvantages existing in the prior art. Most of the wastewater generated during the common continuous rapid steaming salt-free reactive dyeing treatment does not have good treatment measures. Most of them are directly discharged externally, which is very easy to cause environmental pollution and waste of water source, seriously affecting the environmental protection, water-saving and energy-saving measures of the continuous rapid steaming salt-free reactive dyeing treatment.

[0004] In order to achieve the above purpose, the present invention adopts the following technical scheme: a continuous rapid steaming salt-free reactive dyeing method, including the following steps: S1. Material preparation, which is the step of selecting the raw materials to be subjected to continuous rapid steaming salt-free reactive dyeing treatment as standby materials; S2. Pretreatment, which is the step of pretreating the selected standby raw materials; S3. Dye liquor preparation, which is the step of preparing the corresponding required dye liquor before dyeing the raw materials; S4. Dyeing treatment, which is the step of dyeing the raw materials with the prepared dye liquor; S5. Drying treatment, which is the step of drying the raw materials after the dyeing treatment is completed; S6. Wastewater treatment, which is the step of treating the wastewater after the raw materials are completed with the dyeing treatment; S7. Inspection, which is the step of inspecting the effect of the raw materials after the dyeing is completed; S8. Packaging, which is the step of packaging the raw materials after the inspection treatment is completed.

[0005] As a preferred embodiment, in step S1, according to the information of the articles to be subjected to continuous rapid steaming and salt-free reactive dyeing treatment as required, the corresponding polyester-cotton blended fabric is selected as the standby raw material. After the raw materials are selected, they are neatly arranged. During the arrangement process, check whether the selected raw materials are complete, check whether there are missing parts in the raw materials, observe whether there is a lack of luster on the surface of the raw materials, check whether the raw materials are affected by dust, and classify and place the defective raw materials and the intact raw materials separately.

[0006] By adopting the above technical solution, through the design of raw material preparation, the raw materials to be subjected to continuous rapid steaming and salt-free reactive dyeing treatment are selected in advance, which is convenient for subsequent processing of the raw materials, avoids the phenomenon that the efficiency of the dyeing treatment is affected due to the raw materials during the treatment, and improves the dyeing treatment efficiency of the raw materials.

[0007] As a preferred embodiment, in step S2, the intact raw materials are pre-treated. After the raw materials are classified and placed, singeing, desizing, scouring, bleaching, mercerizing and pre-setting are carried out. During the pre-treatment process of the intact raw materials, the defective raw materials are repaired. If there are still problems with the defective raw materials after repair, the raw materials that still have problems after repair are removed, and the intact raw materials after repair are pre-treated immediately after the previous intact raw materials.

[0008] By adopting the above technical solution, through the design of pre-treatment, the raw materials are pre-treated after the raw materials are selected, reducing the probability of defective raw materials appearing in the subsequent processing procedures, and improving the quality of the raw materials used in the dyeing treatment.

[0009] As a preferred embodiment, in step S3, the required dye liquor is prepared according to the selected raw materials and the dyes required for dyeing. The dye liquor is prepared in the padding equipment. Before preparing the dye liquor, water needs to be added to the inside of the padding equipment in advance to facilitate the normal preparation of the dye liquor. After the dye liquor is prepared, the dye liquor waits for the input of the raw materials in the padding equipment.

[0010] By adopting the above technical solution, through the design of dye liquor preparation, the relevant required dye liquor is prepared in the padding equipment in advance, avoiding the phenomenon of preparing the dye liquor when the raw materials start to be dyed, improving the preparation efficiency of the dye liquor, and improving the dyeing efficiency of the raw materials.

[0011] As a preferred embodiment, in step S4, the pretreated raw material is padded in a padding device, and the raw material comes into contact with the dye liquor in the padding device and is padded in the dye liquor. The padding device is started to continuously pad the raw material. During the padding process of the raw material and the dye liquor, the steaming device is adjusted according to the environment required for the steaming of the raw material, and the corresponding temperature and time required for the steaming of the raw material by the steaming device are adjusted. After the steaming temperature and steaming time of the steaming device are both adjusted, the raw material that has completed continuous padding is taken out of the padding device and put into the steaming device. The raw material is steamed in the steaming device until the steaming treatment of the raw material is completed. The raw material that has completed the steaming treatment is taken out of the steaming device, and the raw material is washed by a washing device until the raw material completes the continuous rapid steaming salt-free reactive dyeing treatment.

[0012] By adopting the above technical solutions, through the design of the dyeing treatment, the raw material completes the continuous rapid steaming salt-free reactive dyeing treatment by continuous padding treatment, steaming treatment and washing treatment, so that the raw material has good continuous rapid steaming salt-free reactive dyeing treatment measures and improves the dyeing efficiency of the raw material.

[0013] As a preferred embodiment, in step S5, the raw material that has completed the washing treatment is taken out of the washing device, and the raw material is put into a relevant drying device for drying after being taken out. Before the raw material is put into the drying device, it is necessary to adjust the drying temperature and drying time of the drying device. The drying device is adjusted accordingly according to the drying temperature data and drying time data required for the drying of the raw material. After the adjustment of the drying device is completed, the raw material can be put into the drying device for drying treatment. After the raw material is put in, the drying device is started to dry the raw material until the raw material is dried by the drying device.

[0014] By adopting the above technical solutions, through the design of the drying treatment, the drying device is used to dry the raw material that has completed the washing treatment, so that the raw material has good timely drying measures after completing the continuous rapid steaming salt-free reactive dyeing treatment, avoiding the phenomenon that the continuous rapid steaming salt-free reactive dyeing treatment effect of the raw material is poor due to the raw material remaining wet for a long time after being washed, improving the efficiency of timely drying of the raw material, and improving the effect of the continuous rapid steaming salt-free reactive dyeing treatment of the raw material.

The primary filtration is a step of performing primary sedimentation filtration on wastewater in a treatment tank. The wastewater undergoes sedimentation filtration in the wastewater treatment tank. Before the wastewater undergoes sedimentation filtration, it is necessary to adjust the temperature of the treatment tank so that the temperature in the treatment tank can meet the requirements for the generation of relevant precipitates in the wastewater. 6.2) Preparation of the conditioning liquid. The preparation of the conditioning liquid is a step of preparing a relevant pH neutralization conditioning liquid according to the components of the wastewater. Use a relevant pH value detection instrument to test the wastewater in the treatment tank to obtain relevant data of the wastewater, and prepare the relevant conditioning liquid according to the obtained data information. 6.3) pH neutralization and conditioning treatment. The pH neutralization and conditioning treatment is a step of performing neutralization and conditioning treatment on the wastewater in the treatment tank. After the wastewater completes sedimentation filtration in the treatment tank, the pH neutralization and conditioning treatment of the wastewater begins. Pour the prepared conditioning liquid into the treatment tank. The conditioning liquid comes into contact with the wastewater in the treatment tank, and the wastewater undergoes pH neutralization and conditioning treatment in the treatment tank with the help of the conditioning liquid. 6.4) Secondary filtration. The secondary filtration is a step of performing secondary sedimentation filtration on the wastewater in the treatment tank. After the wastewater completes the pH neutralization and conditioning treatment, the wastewater is again subjected to sedimentation filtration in the treatment tank. When the treatment tank performs secondary sedimentation filtration on the wastewater, temperature adjustment is not required, and it can be directly filtered. The treatment tank filters the precipitates generated during the pH neutralization and conditioning treatment of the wastewater. 6.5) Reuse. The reuse is a step of reusing the treated wastewater. The wastewater that has completed sedimentation filtration is discharged from the treatment tank, and the discharged water source enters the padding equipment, steaming equipment, and washing equipment again for use by the padding equipment, steaming equipment, and washing equipment.

[0016] By adopting the above technical solutions, through the design of wastewater treatment, when the raw material completes the continuous rapid steaming and salt-free reactive dyeing treatment, the wastewater generated during the dyeing treatment of the raw material is treated, enabling the wastewater to have good treatment measures, avoiding the phenomenon of direct discharge of wastewater to the outside, which causes environmental pollution and water source waste, improving the wastewater treatment measures, reducing the probability of water source waste, and enhancing the environmental protection and water-saving and energy-saving measures of the continuous rapid steaming and salt-free reactive dyeing treatment of the raw material.

[0017] As a preferred implementation manner, in step S7, the raw material after drying treatment is inspected. Use a detection instrument to detect whether the various data of the raw material after continuous rapid steaming and salt-free reactive dyeing treatment meet the standards. If all the data meet the standards, it indicates that the raw material meets the required standards after dyeing treatment.

[0018] By adopting the above technical solutions, through design inspection, the raw materials after a series of processing are inspected, and the final various data of the raw materials are inspected to ensure that all the data of the raw materials meet the standards, improve the inspection measures for the raw materials after continuous rapid steaming and salt-free reactive dyeing, and improve the quality effect of the raw materials after continuous rapid steaming and salt-free reactive dyeing.

[0019] As a preferred embodiment, in step S8, the inspected raw materials are packaged by packaging equipment, and after the packaging of the inspected raw materials is completed, they are stored.

[0020] By adopting the above technical solutions, through design packaging, the inspected raw materials are packaged by packaging equipment, reducing the probability of the dyed raw materials being stored naked, and improving the storage measures for the raw materials after continuous rapid steaming and salt-free reactive dyeing treatment.

The wastewater is treated with pH neutralization and conditioning treatment in the treatment tank with the aid of the conditioning solution. 6.4) Secondary filtration, the secondary filtration is the step of secondary sedimentation filtration of wastewater in the treatment tank. After the wastewater has completed the pH neutralization and reconciliation treatment, the wastewater is again subjected to sedimentation filtration in the treatment tank. When the treatment tank again performs sedimentation filtration on the wastewater, temperature adjustment is not required, and direct filtration is sufficient. The treatment tank filters the precipitate generated during the pH neutralization and reconciliation treatment of the wastewater; 6.5) Reuse, the reuse is the step of reusing the treated wastewater, the wastewater after sedimentation and filtration is discharged from the treatment pool, and the discharged water source enters the padding equipment, steaming equipment and water washing equipment again for use by the padding equipment, steaming equipment and water washing equipment.
