The dyeing process of the dyeing machine

The correct pile of yarn tubes of the dyeing machine can ensure small dyeing differences. The height of our dyeing tubes must be the same, and the pressure on the tubes must be uniform. Also, the cheese dyeing machine usually uses a centrifugal pump, which must have enough power to maintain the flow of the dye solution. Usually 5 cycles per minute. The sealing port of the pump must be checked regularly to prevent the ingress of air from causing local oxidation and uneven dyeing of the dye solution. The other thing to pay attention to is the correct adjustment of the process parameters and the choice of chemical additives. The problem of dyes should be emphasized. The particle size of the dye is very important in the dyeing of cheese. After many studies, we found that the particle size of the dye is 3 microns. about. Vat dyes have excellent dispersion and level dyeing properties on the cheese.
