Disadvantages Of Cold Pad Batch Dyeing

Date:Apr 28, 2020

Disadvantages of Cold Pad Batch Dyeing(CPB)


Compared to other reactive dyeing methods, such as jet dyeing, the disadvantages of CPB include:


The dyed fabric production rate is low – requires least 12hours batching time for dye fixation

Difficult to make amendments to off-shade batches so pressure to get things right first time

Process not viable unless high-quality machinery is used

Requires off-line bleaching and wash off which makes planning more complex

Requires an intermediate drying process after bleaching

Requires fabrics to have completely uniform moisture and temperature throughout to achieve optimum results

Ideally requires a chiller for dyes and thermo-regulated room for dye fixation
