Properties Evaluation of Tencel/Cotton Nonwoven Fabric Coated with Chitosan for Wound Dressing

In this study, different Tencel/cotton ratios and needle punching densities were used to make Tencel/cotton nonwoven, which was then coated with chitosan to fabricate a double-layer wound dressing. The nonwoven-chitosan dressing, prepared by using the immersion-precipitation phase-inversion method, had properties that could control the evaporation water loss, promote the fluid drainage, and inhibit the invasion of exogenous micro-organisms. These results indicated that the nonwoven-chitosan membrane could be a potential material for use as a wound dressing.
