Key points of operation

1. Key points of chemical operation: check the accuracy of the prepared dyes and chemicals according to the prescription.

2. Operation points of dyeing process: When dyeing, the machine cover should be closed before heating up, and the operation of gray cloth in the machine should be observed by the glass viewport at any time, and the abnormal sound and phenomena in all parts of the machine should be checked.

3. Main points of dyeing cylinders: When washing cylinders, open all valves of each pipeline to make the washing fluid unimpeded, and discharge high-temperature sewage after heat preservation.

Common problems and causes of dyeing:

1. Dyeing spots and spots: dye condensation produces oligomers in the dyeing bath.

2. Non-uniform color: heating too fast, holding time is short, cloth circulation speed is too slow, cloth capacity far exceeds the standard capacity.

3. Entanglement: Bundle knotting can lead to shutdown, especially when using full-filled equipment and dyeing light and thin fabrics, this kind of trouble is greater.

4. Furring: The nozzle is too small directly, so that the pressure of the nozzle is too high.
