In this study three types of nanodisperse dyes were prepared using oil in water nanoemulsions and applied on microdenier polyester fabric. Nanoemulsions were prepared by three methods: ultrasonication, phase inversion composition and spontaneous emulsification process. Nano scale level emulsion was obtained by all the three methods evidenced by Dynamic Light Scattering method. The dyeing characteristics of micro denier polyester dyed with crude disperse dyes using these nanoemulsions and that dyed with commercial form of same dyes was compared. Dyeing of very high color depth was obtained using these nanoemulsions thus eliminating the requirement of milling of the crude disperse dye with the dispersing agent resulting in cost, time and energy savings.Keywords

In a fast breeder reactor, the liquid sodium coolant is circulated through the core using vertical centrifugal pumps. These pumps are critical equipment for reactor operation and they have many unique design features. Indigenous development of pumps is vital for the demonstration and expansion of fast reactor technology which constitutes the critical second stage of our three-stage programme.
Indigenous design and development of vertical centrifugal sodium pumps was taken up more than two decades ago in close collaboration with Indian industry. This article provides an account of the work done in the areas of pump hydraulics, mechanical design and testing, and manufacture.
