In this study, polypropylene nonwoven fabric grafted with acrylic acid, then immobilized with a mixture of Rhizochitosan and collagen by glutaraldehyde as cross-linker. Experimental result shows that the wound dressings didn't caused the dermal irritation from animal test. The immobilizing ratio of Rhizochitosan/collagen at 2:1 on the modified P.P. nonwoven could obtain good results for the derma wound healing. In addition, the result of the wound dressing for the in vitro cytotoxicity test is negative.
