Preparation of Degradable Tencel Composite Dressings
Tencel® is famous for its green manufacturing process and biodegradable ability. In this study, Tencel® was used as dressing matrix materials owing to its good water absorption and smooth fiber surface. Tencel® nonwoven fabric is prepared by needle punching. Then pectin/Chitosan composite solution was coated onto the Tencel® nonwoven fabric to fabricate pectin/Chitosan/Tencel® composite dressing. The best parameters were prepared by compounding the 3 wt% pectin and 1 wt% Chitosan in volume ratio of 60/40 for good moisture retention, proper swelling rate and slower degradable speed. Coating the pectin/Chitosan solution onto the Tencel® fabric brought low the pectin/Chitosan/Tencel® composite dressing’s permeability by 40%. Nevertheless, tensile strength and tearing strength of that pectin/Chitosan/Tencel® composite fabric were improved by 11% and 2%, respectively.
