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. Long lengths are pulled over the winch and sewn together to form an endless rope. The winch dyeing machine allows fabric ropes pulled from the front and dropping back into the dye liquor. The winch or beck dyeing machine is one of the oldest forms.
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 as
