Washing-off of reactive dyeings usually involves a considerable number of rinsing and soaping steps that results in a large consumption of water. These steps obviously depend upon the depth of shade, but is note unusual to have seven operations during the wash-off. The current recommendations from dyestuff manufacturers are very consistent upon their washing off recommendations. It notes that in order to optimize the washing-off process it is necessary to reduce the affinity of the hydrolysate for the substrate even in the presence of high concentrations of salt or water-hardening substances. This is achieved by using Cyclanon XC-W which enables the dyer to use less rinsing operations. The use of Cyclanon XC-W produces a significant improvement over the standard process on account of the high affinity of the auxiliary for the dye and dye hydrolysate even when salt and water-hardening substances are present.
