Pretreatment of wool fibres with nonionic auxiliary products recommended for low‐temperature dyeing resulted in an increase in dyebath exhaustion and a faster rate of dyeing. This indicated that the auxiliary product was absorbed to a certain extent by the wool. This absorption occurred rapidly and produced an increase in dyebath exhaustion and improved the levelness of the resultant dyeings
