Dyeing treatment with a high-temperature dyeing machine often encounters problems with jamming. After analysis, it is found that after the fabric enters the machine, it must be smoothly and smoothly slid for 3 to 5 minutes, then closed and fed. Sometimes, due to the change of processing varieties, some devices on the machine have not been adjusted, such as liquid return valves, nozzles, etc. Anxious to dye to produce a mechanical blockage.
Or in the process of printing and dyeing some light and high-density fabrics, these fabrics still float on the liquid surface after entering the high-temperature dyeing machine, such as not filling the full overflow mode, plus the liquid return valve heat exchanger and the filter screen. The effect is not to take measures such as adding oxygen scavengers in the dyebath to allow the air to be discharged from the fibers. The fabric is easy to tie the cloth. In this case, it is necessary to formulate a suitable process according to the type of the fabric, and to select a suitable method. Agent to prevent blocking.
In addition, during the operation, the staff needs to observe the operating status of the high-temperature dyeing machine at any time. If it is found that there is a problem of blocking cloth, it should be eliminated in time. When the fabric is fed into the machine, sometimes no defoaming agent is added or the amount is not added, or the foam suppression effect is poor. Even if the water hardness is high, foam will occur at normal temperature, thereby generating a "pneumatic stroke" and forming a blockage. When dyeing should be added before the foam appears, such a foam suppression effect is better.www.textiledyeingmachines.com
