Maintenance Schedule Of Exhaust/Jigger Dyeing Machine


  1. To know the different parts of the machine
  2. To understand the mechanism of the machine
  3. To learn the operation of the machine
  4. To find out the main maintenance points of the machine

Main parts:

  1. Auxiliary roller
  2. Guide roller
  3. Take up roller
  4. Let off roller
  5. Steam channel
  6. Dye bath

Utilities required:

  1. Water
  2. Steam
  3. Electricity


  1. Motor rpm: motor rpm should check to maintain the proper revolution as we need.
  2. Proper movement of roller: every free roller should move freely as required. We need to ensure the free movement of these rollers.
  3. Correct take up & let off: we have to look at the smooth take up of dyed fabric and proper let off of grey fabric with out excessive tension in dyeing.
  4. Proper concentration of liquor: without even concentration of dyeing liquor even shade would not be achieved. Proper concentration of dye bath is necessary to ensure even and proper shade.
  5. Temperature of bath: proper temperature of the dye bath should maintain constantly and should rise and lower evenly with the gradient as require.
  6. Roller movement: different roller like feed roller, let off roller etc should move smoothly as required.
