Analysis of Causes of Cloth Blocking in Overflow Dyeing Machine

①After the fabric enters the machine, it must go smoothly for 3~5 minutes, and then close the door and add the material. Sometimes due to the change of processing varieties, and some devices on the machine have not been adjusted, such as the liquid return valve, nozzle, etc., it is eager to dye As a result, mechanical clogging occurs;

②Sometimes, for some light, thin and high-density fabrics, such as pongee fabrics and polyester towers, they do not sink but float on the liquid surface after entering the machine. The influence of the exchanger and filter screen, etc., and do not take measures such as adding oxygen scavengers in the dyeing bath to let the empty oxygen in the fiber discharge, the fabric is easy to knot and block the cloth, so it depends on the fabric, ordering the craft, and choosing assistance. To prevent problems from occurring;

③When the operator feeds the fabric into the dyeing machine, everything will be fine! However, it is still necessary to pay attention to whether the fabric in the machine is clogged from time to time. Once it is discovered that the recoil clogging device is activated immediately, it is easy to eliminate it. If the time is long, the set will become deeper and deeper. Work hard

④After the fabric is fed into the machine, does the foam in the dyeing bath increase? Because sometimes the defoamer is not added or the amount is not enough, or the anti-foaming effect is poor, or even the water hardness is high, the foam will occur at room temperature, resulting in "pneumatic stroke" and the formation of clogging.
