Treatment of Cotton Fabrics using Polyamines for Improved Coloration with Natural Dyes Extracted from Plant and Insect Sources

Type: article

Abstract: The color strength of the modified colored cotton fabric with polyethyleneimine (PEI) or chitosan using cochineal and moringa natural dyes was examined in this study. Polyethyleneimine and chitosan therapy have led to remarkable increases in cotton fabric dyeability according to colorimetric tests. The fabric treated with polyethyleneimine or chitosan was successfully dyed at lower temperatures in lower time than the untreated one. The change in the dyebath pH shows that the electrostatic force plays a significant role in color adsorption. The fastness properties, tensile strength, and elongation at a break of colored cotton were enhanced following treatment. The scanning electron microscopic (SEM) and Fourier Infra-Red FT-IR analysis proved that cotton fabric has been coated with a thin and consistent polyethyleneimine or chitosan layer, which enhanced cotton fabric coloration with moringa and cochineal dyes.
