Abstract: 

Dyeing on textile substrates such as cotton, silk and polyester was carried out by the conventional method. Dyeing was carried out in open dye bath. Cotton fabrics were dyed with Reactive, Direct and Vat dyes. Silk fabric was dyed with Acid dyes. Polyester fabric was dyed with Disperse dyes. In another method and in order to produce color on conductive fabric by a greener route (without using auxiliaries and heat), fresh textile substrates were subjected to electrochemical polymerization with pyrrole and then immersed in the dye solution at room temperature. The effects of surfactants (sodium dodecyl sulphate, Cetyl trimethylammonium bromide) and dopants (n-tetrabutylammonium tetrafluoroborate, 1-butyl-3-methylimidazolium tetrafluoroborate) in the polymerization were studied. The polymerized fabric containing the dye (colored) was then measured using Computer Color Matching (CCM) analysis to assess the dye uptake. Crease recovery angle of the fabrics was measured. Electrical conductivity of conductive fabrics was measured by electrochemical impedance spectroscopy. Surface morphology was tested with SEM images
