PAD-BATCH DYEING

 

The pad-batch is a cold dyeing process; the raw fabric goes through a batch (composed of dyestuffs and alkali). The textile is then squeezed between two cylinders.

 

 

 

The dyeing process includes three operations:

 

•           Fabric padding

•           Squeezing (unfixed dyestuff wash-off)

•           Rolling and rotation of the fabric


The dyeing batch is supplied by a dispenser pump.

Conditioning cabinet

 

After dyeing, the fabric is packed and stored in a 20°C room and remains in rotation in order to achieve a better impregnation. The time to achieve the fixation is determined by the type of dyestuffs.

 

 

Wash off

After rotation, the fabric is washed off in a continuous washing machine to optimize the fixation of the dyestuffs and to eliminate the excess or insufficiently fixed dyestuffs.
