How to operate the dye jigger

1. Preparation before operation
Equipment inspection:
Check whether all parts of the dye jigger are intact, including the reel, cloth guide roller, squeeze roller, motor, transmission device, heating device, cooling device, etc. Ensure that the equipment is leak-free, unblocked, undamaged, and that all parts are firmly connected.
Check whether the electrical system is normal, and whether the indicator lights, buttons, instruments, etc. on the control panel are sensitive and reliable. Confirm that the equipment is well grounded to ensure safe operation.
Cleaning:
Before using the dye jigger, the equipment needs to be thoroughly cleaned. Remove residual dyes, auxiliaries and impurities in the dye vat, rinse the dye vat and pipes with clean water, and ensure that the inside of the equipment is clean and tidy.
You can use a special detergent or a high-pressure water gun for cleaning. For some difficult-to-clean parts, you can use a brush or other tools to clean them.
Fabric preparation:
Choose suitable fabrics for dyeing according to dyeing requirements. Factors such as the material, weight, and size of the fabric will affect the dyeing effect, so you need to choose according to the actual situation.
Pre-treat the fabric, such as desizing, scouring, bleaching, etc., to remove impurities and sizing agents on the fabric and improve the water absorption and dyeing performance of the fabric. The pre-treatment method and process need to be selected according to the material and dyeing requirements of the fabric.
Preparation of dyes and auxiliaries:
Select appropriate dyes and auxiliaries according to dyeing requirements. The type, color, concentration and other factors of the dye will affect the dyeing effect, so it is necessary to select according to the actual situation.
Dissolve and mix the dye and auxiliaries in a certain proportion to prepare a dye solution. The concentration, pH value, temperature and other factors of the dye solution need to be adjusted according to the properties of the dye and dyeing requirements.
2. Equipment operation
Loading:
Load the prepared fabric onto the reel of the dyeing machine, pay attention to the placement and density of the fabric, and ensure that the fabric can be evenly wound on the reel to avoid folding, winding and other phenomena.
Determine the appropriate loading amount according to the weight and size of the fabric. Generally speaking, the loading amount should not be too large or too small to avoid affecting the dyeing effect and the operating stability of the equipment.
Inject dye liquor:
Inject the prepared dye liquor into the dye vat of the dye jigger through the pipeline, pay attention to the flow rate and pressure of the dye liquor to avoid leakage or uneven spraying.
Determine the appropriate bath ratio, that is, the weight ratio of fabric to dye liquor, according to the material and dyeing requirements of the fabric. The size of the bath ratio will affect the dyeing effect and the utilization rate of the dye. Generally speaking, the bath ratio should not be too large or too small, so as not to affect the dyeing effect and cost.
Heating:
Start the heating system of the dye jigger and gradually heat the dye liquor to the temperature required for dyeing. The heating speed needs to be adjusted according to the properties of the dye and the dyeing requirements. Generally speaking, the heating speed should not be too fast or too slow, so as not to affect the dyeing effect and the operating stability of the equipment.
During the heating process, the dye liquor needs to be stirred continuously to ensure that the temperature of the dye liquor is evenly distributed to avoid local overheating or overcooling. At the same time, it is necessary to closely observe the color changes of the dye liquor and the dyeing of the fabric, and adjust the heating speed and temperature in time.
Dyeing:
When the temperature of the dye liquor reaches the temperature required for dyeing, start the motor of the dyeing machine to slowly wind and unfold the fabric in the dye liquor for dyeing. The dyeing time needs to be adjusted according to the nature of the dye and the dyeing requirements. Generally speaking, the dyeing time should not be too long or too short, so as not to affect the dyeing effect and the operating stability of the equipment.
During the dyeing process, the dye liquor needs to be stirred continuously to ensure that the concentration of the dye liquor is evenly distributed to avoid the phenomenon of local concentration being too high or too low. At the same time, it is necessary to closely observe the color changes of the dye liquor and the dyeing of the fabric, and adjust the dyeing time and temperature in time.
Cooling:
When the dyeing time is over, gradually reduce the temperature of the dye liquor for cooling treatment. The cooling speed needs to be adjusted according to the nature of the dye and the dyeing requirements. Generally speaking, the cooling speed should not be too fast or too slow, so as not to affect the dyeing effect and the operating stability of the equipment.
During the cooling process, the dye liquor needs to be stirred continuously to ensure that the temperature of the dye liquor is evenly distributed to avoid local overheating or overcooling. At the same time, it is necessary to closely observe the color changes of the dye liquor and the dyeing of the fabric, and adjust the cooling speed and temperature in time.
Cleaning:
When the temperature of the dye liquor drops to room temperature, the dye liquor is discharged from the dye vat of the dyeing machine, and the fabric is cleaned with clean water. The number of cleaning times needs to be adjusted according to the dyeing requirements and the amount of residual dye on the fabric. Generally speaking, the number of cleaning times should not be too little or too much, so as not to affect the dyeing effect and cost.
During the cleaning process, the clean water needs to be stirred continuously to ensure that the clean water can fully contact the fabric and remove the residual dye and auxiliaries on the fabric. At the same time, it is necessary to closely observe the color changes of the clean water and the cleaning of the fabric, and adjust the number and time of cleaning in time.
Out of the cloth:
When the fabric is cleaned, the fabric is taken out of the reel of the dyeing machine for dehydration and drying. The method and process of dehydration and drying need to be selected according to the material and dyeing requirements of the fabric.
During the process of discharging the cloth, it is necessary to pay attention to the placement and density of the fabric to avoid folding, winding and other phenomena. At the same time, the fabric needs to be inspected to ensure that the dyeing effect of the fabric meets the requirements.
3. Precautions
Safe operation:
When operating the dyeing machine, it is necessary to strictly abide by the operating procedures to ensure the safe operation of the equipment. Operators need to wear protective equipment, such as gloves, masks, goggles, etc., to avoid contact with dyes and auxiliaries to cause harm to the body.
During the operation of the equipment, it is necessary to closely observe the operating status of the equipment, such as temperature, pressure, flow and other parameters, and promptly detect and deal with equipment failures. If the equipment is found to be abnormal, the operation should be stopped immediately and the relevant personnel should be notified for maintenance.
Environmental protection requirements:
During the dyeing process, it is necessary to pay attention to environmental protection requirements to avoid dyes and auxiliaries from polluting the environment. Environmentally friendly dyes and auxiliaries can be used to reduce the discharge of wastewater, waste gas and waste residue. At the same time, wastewater can be treated, dyes and auxiliaries can be recycled, costs can be reduced, and the environment can be protected.
Quality control:
During the dyeing process, the dyeing quality needs to be strictly controlled to ensure that the dyeing effect of the fabric meets the requirements. Advanced testing equipment and methods, such as colorimeter, color fastness tester, etc., can be used to detect and control the color, color fastness and other indicators of the fabric. At the same time, the dyeing process can be optimized and adjusted to improve the dyeing quality and efficiency.
