  • Machine name : OSHTOFF singeing machine
  • Made : GERMANY
  • Process : Gas singeing
  • Source of flame : L.P.G.
  • Pressure of L.P.G.: 1.5 bar
  • Flame height : 6” approx
  • Temperature of flame: 1100 ̊C
  • Speed of fabrics : 100 m/min
  • Colour of flame : blue
  • Flame intensity: depends upon the G.L.M. of fabrics 
OSHTOFF singeing machine
Table of GLM and Flame Intensity:

Flame intensity
Upto 300
300 to 400
About 400

No of gas burner: two (2)
Note: filaments are not singed in order to avoid bead formation on the surface of the fibre.

Desizing is done in order to remove the size materials that applied on weaving to improve weave ability. Here use enzyme desizing.

Machine Parameter:
  • Nip pressure: 0.8 bar
  • Capacity of trough: 750 lit.
Chemical Recipe:
  • Enzyme: 5 g/l
  • Wetting agent: 4 g/l
  • Complexer : 1 to 1.5 g/l
  • Temperature: 85 ̊C
  • pH : 6 to 9.5
  • Speed: 80 to 100 m/min
  • Enzyme used: Palkozyme Plus.
Process Sequence:

Pre-brushing unit


Dancer Roll

Post brushing

Padding with desize(85 ̊C)

Batch formation

Keep the batch in rotation for 8 to 12 hours
  1. Ensure lift working properly
  2. Batch should be rotated 8 to 12 hours
  3. Ensure the right batch is given on desize washer as per the programme of desize washer.
