5. Different Parts of a Dyeing M/c.

6. 1. Jigger Dyeing Machine

7. Features of Jigger Dyeing Machine
Discontinuous Dyeing.
Most commonly used pieced dyeing m/c.
Fabric is dyed in open width in uniform tension.
Fabric moves but liquor does not circulate.
It is used specially for woven fabrics.
Rollers rotate clockwise and anticlockwise.

8. Technical Details of Jigger Dyeing Machine
1. Fabric tension 50 - 800 N
2. Fabric speed 10 to 150 m/min
3. Fabric width up to 5400 mm
4. Roller width up to 5600 mm
5. Roller diameter 330 - 550 mm
6. Batch diameter 1000/1230/1450 mm
7. M:L 1:7 to 1:10
8. Time required 4-10 hours
9. Fabric can be dyed 500-1000 yards
10. Temperature and pressure Normal atmospheric pressure and under 1000C

9. Main Parts of the Jigger Machine

15. Winch Dyeing Machine

16. Features of Winch Dyeing Machine
Discontinuous Dyeing.
Fabric is dyed in rope form in this m/c.
It is used specially for Knit fabrics.
Fabric moves but liquor does not circulate.
Rollers rotate clockwise and anticlockwise.
Heating can be supplied by means of direct or
indirect stem heating.

17. Technical Details of Winch M/c
1. Fabric tension Little Tension
2. Maximum fabric speed approximately 40m/min.
3. Capacity per nozzle theoretically 250 kg but practically not more than
200 kg.
4. Reel/Winch speed 150-250 rpm
5. M:L 1:20 to 1:40
6. Time required Lengthier than other m/c.
7. Nozzle pressure 4-6 psi
8. Maximum Temperature 140 for high temp. M/c & 100 for atmospheric
9. Main motor efficiency 80-85%

18. Main Parts of the Machine
Winch
Water inlet pipe
Steam pipe
Dyeing tank
Drain valve

20. operation
is simple.
Used for
knit
fabric.
Soft and
durable
Dyed in
rope form
Suitable
for
desizing
to
softening.
Less

exerted
on fabric.
Advantages of Winch M/c

21. Difficult to maintain
uniform temp.
Discontinuous
Process.
Product cost higher.
Heat consumption
high.
Permanent crease
may occur.
Needs sewing,
opening, loading etc.
Disadvantages of Winch M/c
