Yarn Package Dyeing Machine DW202B

Yarn Package Dyeing Machine has one dyeing cylinder. Water and dyestuff are added into the cylinder firstly and mixed evenly. Then place the bobbin yarn into the cylinder. After the heating tube starts working, the temperature and pressure in the cylinder will rise and then the bobbin yarn can be dyed effectively in an environment of high temperature and high pressure.

Feature of Package Dyeing Machine:

  • Surface treatment: Stainless steel construction with sand blasting surface treatment; inner surface of dyeing cylinder use acid etching treatment to protect cylinder against dyes;
  • Free control of dye liquor flow: The bobbin yarn is placed on the mandril in the dyeing cylinder. The dye liquor can flow out and back from the holes in the mandril. Internal flow and external flow can be switched freely inside the dyeing cylinder according to the dyeing process.
  • High automation: Dyeing process can be controlled manually or automatically. The temperature and water level in dyeing cylinder can be preset by dyeing computer. Real-time pressure in dyeing cylinder is indicated by pressure gauge;
  • High-temperature protection: Opening the lid of cylinder is not allowed when the temperature in dyeing cylinder reaches the preset temperature, such as 85℃.
  • Water-level protection: The service cylinder of DW241B is equipped with water level sensor to prevent water level exceeding the preset water level, such as high level;
  • Lock protection:The package yarn dyeing machine has special cylinder lock can fix the lid of dyeing cylinder to prevent moving in the dyeing
  • Optional heating methods: With rich experience in lab design, dyeing machines with steam heating function are normally suitable for dyeing mills, because they have the ability to provide steam source to heat the dye liquor; as for university, institute, etc, we can provide dyeing machine with electrical heating function.
