3. Introduction
1. Beam dyeing is simply a much larger version of
package dyeing.
2. This method is similar to package dyeing but is
more economical.

5. Working Principle
1. The fabric or yarn in open width is rolled on to a
perforated beam.
2.The beam then subsequently inserted into a
dyeing vessel.
3.The machine is closed and pressurized.
4.The dye liquor is circulated in to out and out to in
directions , under pressure and temperature is
employed as per the process requirement.
5.The chemicals and auxiliary are injected as per
requirement of the process.

6. Maintenance
• Cleaning of the machine-Every batch unloaded
• Checking the water pipe-Everyday
• Checking the motor and electric connection-Weekly
• Checking the flow of water-Every hour
• Steam pressure regulator checking -Every hour
• centrifugal pump maintenance-Clean bearing,Check oil
drain plug,Lubricate the bearings
• Heat exchange-cleaning inner tubes and the outer side

7. Discussion
• Circulation of dye liquor through stationary beam of
fabric in open width.
• beam dyeing machines relatively consume more water
and energy both and increases cost of dyeings
• As the fabric is being dyed in open width, rope and
crease marks are not developed
