رنگرزي پلي استر با استفاده از نانوپيگمنتها در محيط مافوق صوت

Polyester fiber has compact structure and we have problems for its dyeing. So, in the present study, by using nano-pigment has a particle size less than 400nm but using of Pigments isnʹt used for polyester dyeing. In this article acceptable results get by using new technology of ultrasonic and urea as swelling agent in compare with samples without urea. Samples are used urea and ultrasonic process the aim of this research was to investigate.
