Exhaust dyeing machines for polyester

  1. 1. SEMINAR ON OPEN WIDTH EXHASUT DYEING MACHINE FOR POLYESTER BY: NISHANT CHHABRA ISO No: 10TXCH30 Roll No: 22
  2. 2. METHODS OF DYEING POLYESTER FIBRE
  3. 3. OPEN WIDTH EXHASUT DYEING OF POLYESTER  For open width exhaust dyeing of polyester m/c that can be used are: HYDRAULIC JIGGER DYEING MACHINE BEAM DYEING MACHINE
  4. 4. HYDARULIC JIGGER DYEING MACHINE
  5. 5. LINE DIAGRAM
  6. 6. REDUCTION IN MATERIAL TO LIQUOR RATIO CONVENTIONAL DESIGN OF JIGGER MODERN ‘V’ SHAPED JIGGER
  7. 7. RECENT ADVANCEMENT IN JIGGERS  ROOF CLEANING SPRAY
  8. 8. CONT…  SELF CLEANING FILTER
  9. 9. CONT…  SPRAYING DEVICE
  10. 10. CONT…  CENTRE DRIVEN FREQUENCY CONTROLLED MOTOR DRIVE LOADING/UNLOADING OF FABRIC.
  11. 11. CONT…  FULLY DIGITAL AUTOMATIC OPERATION
  12. 12. INNOVATIONS IN MODERN JIGGERS     Dye trough ensuring minimum liquor ratio. Fabric rope monitoring control system for precise calculation and control of the fabric speed and tension. Water meter for controlled rinsing. Addition pressure pump for shade correction and dosing. On the HT jigger dosing under pressure in possible.
  13. 13. AUTO-TEMPERATURE CONTROLLER
  14. 14. SPECIFICATION OF EQUIPMENT         Temperature observed in jigger-130 deg C Temperature required for hot cycle-80 deg C Water required per day in hot dyeing-2400 lts Saving of Heat per day-38400 kcal/day Fuel saving per day assuming 70% efficiency6.69kg /day Saving per year-~15000 Rs/yr Cost of equipment-12000 Rs/yr General payback period-9.6 months
  15. 15. CIRCUIT DIAGRAM FOR MODERN JIGGER ASSEMBLY
  16. 16. BEAM DYEING MACHINE
  17. 17. LINE DIAGRAM
  18. 18. TECHNICAL SPECIFICATION        Modern beams with compact construction with sealed system. Pressure expansion space above the dyeing kier In-line heat exchanger Flexible working width upto 4000mm Flexible winding diameter Operating temperature max 140 deg Controlled with industrial PC
  19. 19. DIAGRAM OF IN LINE HEAT EXCHANGER
  20. 20. DYEING VESSEL OF BEAM DYEING MACHINE
  21. 21. PERFORATED BEAM
  22. 22. ADVANCEMENT IN DYEING VESSEL AND PERFORATED BEAMS Perforated beams are made up of stainless steel AISI 316 so that problem of rusting in avoided.  The diameter of beam is 500 mm to 600 mm.  As per as diameter of perforated beam is concerned. It may be noted that larger diameter beam less prominent moire effect. 
  23. 23. ADVANCEMENT BY THIES IN BEAM DYEING MACHINES    ANALOG DOSING:- Fully automatic dosing of dyes and auxiliaries according to programmed time and curve(in HT condition also). pH-Fit:- System for pH controlled dyeing and simultaneous fully automatic cleaning and calibration of the pH electrodes. Coupling Device:- Designed as cross coupling, ensuring continuous liquor circulation through both dyeing vessels during coupled operations.
  24. 24. ECONOMICAL BEAM DYEING MACHINE BY DEVREKHA  Exclusive Features  Reduction in liquor ratio :- 1:5  Reduction in water consumption upto 80% per batch.  Reduction in heat energy consumption upto 35%  Reduction in electrical consumption upto 20%  New maintenance and trouble free injector pumps.
