In this study we used ultrasonic technology as a means of
enhancing dyeing process efficiency of polyester fibers with
disperse dyes, which had frequency 42kHz and, we studied the
behavior of dye when the polyester dyed with (US) and with
traditional dyeing methods (without US).
The recent synthesis of the new polymers has been profoundly affected by
the unique characteristics of Dimer Acid.
These polymers were made up following the condensation with
triethanolamine when was treated in melted phase.
We performed identifi
cation of the physical characteristics of the polymers
such as the molecular weight, in addition to the acid value and hydroxyl value.
Infrared spectroscopy have been used in identification of this polymer.
Also, the rheological behavior has been assessed thermally and shearing
stress by using capillary viscometer.
Our results revealed a reduction in the viscosity with increase of the
shearing stress as will as with rise in the temperature.
