| Abstract: | Thermodynamic
parameters and dyeing kinetics for colouration of bleached and selectively
double pre-mordanted jute fabric dyed with purified natural dye powder obtained
from aqueous extract of tesu under optimized dyeing conditions have been
studied to understand the physico-chemical interaction amongst dye, fibre and
mordant. It is observed that this dyeing process is endothermic. Dye absorption
isotherm of this particular fibre-mordant-dye system is found to be linear,
following Nernst absorption isotherm. FTIR spectra of bleached, mordanted and
purified natural dyed (tesu dyed) jute fabrics have also been compared. It is
revealed that dyeing of selectively pre-mordanted bleached jute fabric mostly
occurs through H-bond formation along with minor possibility of co-ordinated
complex formation for fixation of tesu colourant on the selectively double
pre-mordanted jute fibre. |
