Enzymes as auxiliary agents in wool dyeing

Abstract

The action of three enzymes has been comparatively studied when used as auxiliary agents in dyebath. The absorption rate of the dye, the colour differences between wool dyed with and without enzymes and the colour fastness were determined. The action of enzymes consists of increasing dye absorption and also seems to produce a better diffusion of the dye into the fibre. The use of the enzymes in wool dyeing offers the possibility of dyeing under mild temperature conditions.
