Title : Innovation and green chemistry applications of natural dyes on textile fibers pretreated with neem/chitosan nanocomposite and its antibacterial characteristics for saving energy and reducing environmental impact
Abstract:
Wool fibers were dyed using a natural dye extracted from olive leaves and red prickly pear using microwave to save time and energy. Wool fibers were treated with a chitosan/neem nano composite before being dyed with. Investigations were conducted into the dyed wool fibers' fastness characteristics, color strength, color data, and dye concentration and pH variables. According to the data, wool fibers that had been pretreated with the tested nanomaterials performed better than those that untreated. Neem and chitosan nanocomposites have antimicrobial activity.. The antimicrobial activity of different strains of bacteria and fungi was tested . The results obtained indicated that the antimicrobial activity for natural dyes under investigation were good and enhanced by composite improved the antimicrobial activity of the natural dyes under study. Scanning electron microscopy (SEM) was used to analyze the morphologies and structures of the wool fibers that had been processed and those that had not. The unprocessed wool fibers have a rough surface. In contrast to the untreated fibers, the processed wool fibers were swelled. The fibers' diameter grew, The aim of this work is the manufacture of ecofriendly handloome carpets from wool fibers pretreated with the nano composite under invistigation and dyed with natural dyes.
