Types of singeing machine:
1. Plate singeing machine
2. Rotary-cylinder singeing machine
3. Gas singeing machine.
Gas Singeing Machine:
It is
essentially consist of one or more burners giving continuous flat or vertical
flames, produced by a mixture of gas and air. The flame issues from narrow
slit.Which are adjusted with respect to width and thickness burner which stands
the lying projecting fibers. When the cloth is drawn over the flame at a high
speed. The flame impinges on its surface and burns the protruding fibers
without damaging the cloth. The speed of transmission of the cloth through the
machine has to be adjusted to suit the amount of singeing required, without the
risk of burning the cloth.
It is
important to set a drain temperature of the water-cooled roller in a range of
50 to 550C. Cautions are required because a dew-point is generated when the
water-cooled roller is cooled down too much, and results in increased amount of
remaining fuzz or adhered carbon. The fabric feed speed is preferably set at
around 100 to 150m/minute.
