suitable for piece dyeing. A winch is a simple machine. It is equipped with a winch to guide the fabric from the vat. It has a straight front and a curved back.

Principle and parameters
Winch machine is a high liquor dyeing machine operating at 1:20 (MLR) and a maximum temperature of 98 degrees Celsius. In a winch dyeing, the fabric remains in movement while the dye liquor stays stationary similar to a jigger but with lesser stress on the materials. Hence, suitable for delicate textures and fabric types such asknitted fabric
