In this paper, various parameters of warp yarn dyeing using indigo dyes are investigated. These parameters include dye concentration, number of dips in the dyeing process, dyebath pH, amount of reducing agent, immersion time, oxidation (skying) temperature, effects of a wetting agent and soaping temperature. This study revealed that these parameters have varying degrees of influence on the resultant colour of the samples dyed. The degrees of variation in colour were expressed using the CIE L(*)a(*)b(*) system as well as the shade depth (Integ).
