1. The winch dyeing machine dyes fabrics like wool and silk through a process where fabric ropes are circulated through a dye bath and around a winch or reels. 2. It has a front compartment where dyestuffs and auxiliaries are added to the main dyeing chamber gradually. 3. The fabric ropes are immersed in the dye bath and circulated through the dye bath and around the winch, with the dyestuffs being dosed manually or automatically.

3. Winch dyeing machines comes with the lucrative options of low cost design,
simplicity in operation and maintenance yet uncompromising features when it
comes to versatility.
Mostly woollen and silk fabrics are dyed by using Winch Dyeing machine. The
dyeing machine derives its name "Winch" as the fabric rope gets circulated in the
machine by way of a mechanical action of a horizontal rotor or reel, called as a
winch or sometimes wince. The cross‐section of the winch rotor may be circular
or elliptical.
The winch dyeing machine has a front compartment, a perforated partition
separates it from the main dyeing chamber. It is this front compartment where
dyestuff and dyeing auxiliary additions are made. Gradually they move to main
dyeing vessel from there. The process works like this first a series of fabric ropes
are immersed in the dye bath. This fabric ropes must be of equal lengths. A part
of each rope is then taken over two reels or over the winch itself. In the
subsequent course of dyeing operation a rope of fabric is circulated through the
dye bath and the winch. The dyestuff and auxiliaries are dosed manually or
automatically according to the recipe method.

6. Working Principle of Winch dyeing machine:
Winch Dyeing machines are most suitable for knit fabric dyeing. Here fabric is
dyed in tubular from where fabric runs in endless circular path. Inside the m/c
the upper part of the fabric runs through a nozzle & the lower part is immersed
into liquor, in the nozzle the liquor is sprayed onto the fabric. The fabric and
liquor both circulated by a high pressure pump. The main pump draws the
liquor from the bottom of the vessel & passed this liquor through the heat
exchanger to the top of vessel into the Nozzle. The winch roller or the reel also
helps running the fabric smoothly. The liquor gets heated or cooled by
exchanging temperature in the heat-exchanger.

7. 1. Construction and operation of winch are very simple.
2. Easy to enter and easy to operate and let out of the fabric of the m/c.
3. Suitable for dyeing of knitted fabric.
4. The appearance of the dyed goods is clean and smooth on winch dyeing
machines.
5. Knitted fabric is not damage due to low tension.

8. 1. Difficult to maintain uniform temperature.
2. Due to high liquor ratio (1:40) product cost is high.
3. Uneven dyeing due to folding.
4. Discontinuous process.
5. More fabric can’t be dyed.

9. •Capacity per nozzle :
theoretically 250 kg but practically not more than 200
kg should be used.
•Nozzle pressure :
4-6 psi
•Steam pressure:
