Modern demands on textiles and on efficient and ecological production processes require new chemical products which meet these demands. Dyeing auxiliaries provide high dyeing quality, process saf ety and increased reproducibility on all kinds of substrates and machines, in a variety of processes and with all classes of dyestuf f s given effect is to be obtained. For aqueous-based dyeing, dye auxiliaries such as chelating agents, dispersing agents However, auxiliary usage varies according to several factors, such as the particular dye-fibre system employed, depth of shade of the dyeing, machine type, liquor ratio employed (a detailed account of liquor ratio is presented in section 5), etc., as illustrated by Table 2, which shows some of the types of auxiliary that can be employed in the Textile auxiliaries are defined as chemicals of formulated chemical products which enables a processing operation in preparation, dyeing, printing of finishing to be carried out more effectively or which is essential if.
