2.3.3 Gas Singeing Machine
The latest advancement in singeing machine is gas singeing. There are machines
which uses different technique to remove protruding fibres from the fabric surface.
Some of the earlier machines use heated plate or roller for singeing, however, incase
of gas singeing machine, as the name suggests, gas flame is used for this purpose.
Heart of the gas singeing machine is its burner, which is the most advanced part of
the machine. Usually, pre-mixed air and gas mixture prepared using proportional
mixing valve is supplied to the burner which ensures uniform flame across the width.
Ratio of gas to air always remains in accordance with the stoichiometric value so
that irrespective of intensity of flame, its height remains same (Fig. 6).
The machine can be divided into three main sections—inlet, singe unit and
exit section. The inlet section of the machine may be divided into two main subsections—pre-cleaning and inlet. Various sub-assemblies attached in both these
sections include,
• Beating and brushing unit
• Cyclone dust collector
• J-scray
• Fabric guider.
Actual singing takes place in Singeing unit, which have number of sub-assemblies
such as,
• Burner assembly with adjustments
• Gas train and intensity control
• Hairiness tester.
