Reactive dyes are used on cellulosic fabrics to achieve dyeings at reduced cost and with satisfactory fastness properties. This involves large amounts of electrolytes and alkalis, which affect the nature of the effluent. It is shown that sodium chloride cannot be replaced by calcium chloide because it has insufficient capacity to exhaust a reactive dyebath. However, sodium hudroxide can be replaced by calcium hydroxide, especially in exhanust dyeing with reactive dyes at high temperatures.
