A finishing process applied mainly to woollen fabrics. The dyed fabric (which may have crabbed) is batched on a roller and is then immersed in water. The temperature of the liquor an duration of treatment depend on the effect desired. The fabric is cooled on the roller and re-batched end for end and the process is repeated. The fabric is finally wound off the roller and dried.
