One Pot Synthesis of Nanosilver Incorporated Cellulosic Fiber-Based Nonwovens for Wound Dressing Applications

Textile substrates incorporated with antimicrobial agents offer a great advantage in treating chronic wounds infected with microbes. In this work, a simple one-step process is proposed to develop cellulosic nonwoven incorporated with silver nanoparticles using wet laying technique. In order to improve the dispersion of the fibers during wet laying and better binding of silver nanoparticles, the fibers were cationized using CHPTAC. The decrease in absorbance value of the drain at 470 nm confirms binding of nanosilver to the fiber. A maximum zone of inhibition of 18 mm and 19 mm was obtained for cationized web. The developed web can be used for wound dressing applications.
