Grafting of chitosan-acrylamide hybrid on the wool: Characterization, reactive dyeing, antioxidant and antibacterial studies

摘要: Abstract This study presents a new approach to enhance reactive dye uptake and functional finishing of wool yarns via simple grafting with synthesized chitosan-acrylamide (Ch-Ac) hybrid. To this, Ch-Ac was characterized fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) X-ray diffraction (XRD) techniques. Then, grafted on wool, FTIR, SEM, weight gain analysis dyeability two commercial dyes. Results showed that treated could be dyed at lower temperatures (ca. 40 °C), times 30 min), amount (2% owf) as compared raw wool. Also, deeper shades not obtainable in conventional dyeing attained using In addition, treatment imparted very good radical scavenging excellent antibacterial activity against gram-negative (E. coli) gram-positive (S. aureus) bacteria. Color fastness results confirmed had no adverse effect durability dyes washing, light, rubbing perspiration. The this clearly indicated can used eco-friendly enhanced uptake, minimized residual wastewater, saving consumption chemicals, energy, time dyeing.
