Combine Singeing and Desizing of Woven Fabrics

Singeing:
The main object of singeing is to remove the protruding fibres from the fabrics to make the fabric smoother.

Machine Parameter:
  • 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

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

Desizing:
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

Singeing

Dancer Roll

Post brushing

Padding with desize(85 ̊C)

Batch formation

Keep the batch in rotation for 8 to 12 hours
 
Rotation:
  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.
