A study of the initial rate of desorption of direct dyes from cottom fabric into sodium borate solution has indicated a linear relationship between the removed dye, expressed as a percentage of the total dye initially present, and the square root of the time, as in the desorption of level dyeing acid dyes from wool fabric. It also shows that the initial rate of desorption of dyes from cotton fabric is approximately proportional to the affinity value of dye and to the grade number of washing fastness of dyeings. Accordingly, the initial rate of desorption is capable of a quick guide to the washing fastness of dyeings. The results of these studies show that the initial rate of desorption of direct dyes from cotton fabric increases as the depth of dyeing increases, and that, when the depth of dyeing is constant, it is influenced by the dyeing conditions, in particular, the temperature and time of dyeing and the concentration of added neutral electrolyte in dyebath. Also, any treatment which results in an increase in the number of free acidic group, such as oxidation bleaching, increases the rate of desorption of dye in alkaline solution.
