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.

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.
