Modification of wool fabric using prepared chitosan-cyanuric chloride hybrid

چکیده مقاله

<p style="text-align: left;">Abstract</p> <p style="text-align: left;">The current study is a report on the application of prepared chitosan-cyanuric chloride hybrid (Ch-Cy) onto the wool fabric. The Ch-Cy component was synthesized in tetrahydrofuran at 0&deg;C for 24&thinsp;h. Fourier transform infrared (FTIR) spectra were used to prove the interaction between chitosan and cyanuric chloride. The effects of Ch-Cy concentration, temperature, and pH were evaluated on the grafting process. The optimum values for operating variables were achieved with&nbsp;<i>C</i>_{Ch-Cy&thinsp;}=&thinsp;15% (owf),&nbsp;<i>T</i>&thinsp;=&thinsp;70&deg;C, and pH 4&ndash;5. The physical properties of treated wool fabric were premeditated by FTIR, scanning electron microscope and differential scanning calorimetry analysis. The results showed that the Ch-Cy was grafted to the wool structure through the formation of strong covalent bonds. The antibacterial activity of dyed treated wool fabric against&nbsp;<i>Escherichia coli</i>&nbsp;was enhanced and the dyeing capability of treated fabrics in comparison to untreated fabrics was increased. The results from this study obviously indicate that the Ch-Cy hybrid is a high potential antimicrobial and a new environmentally friendly agent for textile fibers.</p>
