Knit Dyeing is a critical procedure and it is required to match the shade of the dyed fabric with the buyer’s approved swatch. Sometimes, it is found that the dyed fabric shade does not match with the approved swatch then this fabric is required to re dyeing. This re dyeing process is called stripping. Most of the time, black shade or deep shade is produced by the stripping process. Topping is another re dyeing process but stripping and topping is use for different case.

Stripping is done on the dyed fabric for this reason this type of re-dyeing increases the cost of the dyeing process.
