increase the dye uptake [26]. US radiations have advantages such as energy saving,
water saving, reduce process time and increase color depth [27]. These rays have
found a widespread industrial application, such as for surface treatment, soldering,
degradation, and formation of emulsions [28, 29]. The decolorization of dyes can
take place by using ultrasound, while ultrasound alone is not effective to obtain
their complete removal. Ultraviolet radiation has also a relatively good potential for
modification of textile processing. Previous studies reported that UV-treatment of
fabric brings about photo-modification of surface fibers and it can allow internal
vicinities of fibers become uptake able to more dye with firm fixation and develops
deeper shades and also enhances the coloration value of fabric and garments [5, 30].
The effect of Ultraviolet treatment considerably depends upon the nature of pigment
and dye, the existing absorptive groups in the dyestuff, penetration after dyeing, the
consistency and additives used in the dyeing processes [4]. Several modifications
and treatments were carried out to improve the dyeability and fastness properties of
different fabrics using natural and synthetic dyes, but the very few studies exist on
the effect of UV radiation treatment on the dyeing of cotton and polyester fabric with
reactive and disperse dye [31].
The major objectives of using these modern tools are
1. Reduce the energy, money and time during textile processing
2. To improve fixation of dye onto irradiated cotton and polyester at mild reaction
conditions using irradiated dye solution
3. To improve the color depth and colorfastness properties through radiation.
4. To reduce the number of chemicals in dye house effluents to make dyeing process
eco-friendly and eco-label.
Following aspects under various dyeing conditions have been discussed in this
chapter and their role has been compared on account of the results obtained.
(i) Effect of microwave treatment (MW) in reactive, vat and disperse dyeing of
cotton and polyester fabric
(ii) Effect of ultrasonic treatment in reactive, vat and disperse dyeing of cotton and
polyester fabric
(iii) Effect of ultraviolet treatment in reactive, vat and disperse dyeing of cotton and
polyester fabric.

The precise methodology of dyeing is given in tabulated form which represent the
improvement in dyeing behavior of reactive dyes under the influence of MW, UV,
US treatment (Tables 1, 2, 3, 4, 5, 6 and 7).
