Abstract:
Natural dyeing is considered as a suitable approach in textile dyeing, which can minimize
the environmental impacts of synthetic dyes. The present study has shown that it is
possible to use the bark of Cinnamomum zyelanicum Blume (cinnamon) to extract natural
dyes using aqueous extraction method for coloring 100% cotton fabric. Cinnamaldehyde
was the agent of interest for the current project as a dyeing agent. In order to fix
cinnamaldehyde on cotton material, metal salts of Cu, Ni, Fe, Al, and Co were used during
experiments. According to the results, a darker shade was seen with FeSO4-mordanted
cotton fabric. A CuSO4-mordanted generated a medium shade. In the cotton samples
mordanted with NiCl2, CoCl2, and (NH4)Al(SO4)2, relatively light colors were seen.
Moreover, the antibacterial activity of dye and dye-fixed fabric against textile bacteria
was investigated. The inhibitory effect was observed using the disk diffusion method.
Cinnamon dye and cinnamon-dyed cotton fabric were not active against the tested bacteria
culture.
