Important Gas singeing parameters :

Following are the important gas singeing parameters:

• Flame intensity
• Fabric speed
• Singeing position
• Distance between flame burner and fabric
• Flame width

Flame intensity: The flame intensity of the singeing burners is based on the amount and the outlet speed of the gas-air mixture leaving the burner slots. Besides having high thermal energy, flame also has considerable mechanical energy. All the thermal and mechanical energy of the flame is directed onto the fabric during singeing. The temperature of the flame at the mouth of the burner is in the range of 1250 to 1300oC. The speed of the flame at the burner outlet may be between 15 and 35 meter per second. The flame intensity usually lies between 5 and 20 mbars.

    

      Fabric speed:The fabric speed in the singeing machine is usually in the range of 50-160 m/min depending on fabric weight (gram per square meter)  and fibre blend. For heavier fabrics, the speed is kept slower as compared to lighter weight fabrics.
