Abstract: Three different dyes derived from the methanolic extract of Cissus populnea as the coupling component with Sulphanilic acid, 4-aminophenol and 4-chloroaniline was successfully synthesized. The identity of the plant extract and dyes were investigated using spectroscopic analysis such as Uv-visible spectrometry and Fourier Transform Infra-red Spectrometry. The dyes absorbed within the visible region of the electromagnetic spectrum DMSO, methanol and acetone but the Uv-visible of the dyes in DMSO was more bathochromic with wavelength range of 605-607 nm as compared to that of methanol (498-500 nm) and acetone (397-403 nm). The infra-red spectra of the extract and dyes confirmed the presence of chromophores such as OH, C=O, N-H, -C-H, C=C and N=N in the dyes, which account for the colored nature of the extract and dyes. The dyes gave brown shades on nylon 6, 6 and exhibited good to very good fastness properties on the dyed fabric. For wash fastness, it was between 3 (good) and 4 (very good), while for light fastness it was between 6 (good) and 4 (moderate).
