  3. Southeast School of Science and Engineering, Department of Textile Engineering University Introduction: Most of the operations in the textile processing such as scouring, bleaching, dyeing and printing are carried out by use of basic chemicals like acid, alkalis oxidizing, reducing agents dyestuffs etc. Besides this other chemical are also used in relatively small quantity proportion to increase the efficiency of above process. These substances are called Textile Auxiliaries. 5/22/2014 3

  4. Southeast School of Science and Engineering, Department of Textile Engineering University What Does Auxiliary Mean in Textiles? It is defined as a chemical or a formulated chemical product which enables a processing operation. The various processing operations may be in the functions of preparation, dyeing, printing or finishing. Auxiliaries help by speeding up these processes or carry out the processes in a more efficient manner. This is necessary to obtain the desired effect. 5/22/2014 4
