Chitosan is a poly-glucosamine obtained after the de-acetylation of chitin.As a natural polymeric material,chitosan is widely available in nature and can be extracted from the shells of crab ,prawn and other types of crustaceans.It also can be prepared by the method of biological fermentation, is a kind of sustainable development characteristics of biological materials.By dissolving chitosan in an acidic solution and ertruding the solution through spinneret holes,it is possible to obtain bioactive chitosan fibers. It can also prepar carboxymethyl chitosan fiber by carboxymethyl.
Properties and Applications
Chitosan is a natural antibacterial material, this kind of fiber has excellent biocompatibility,biodegradability and wound healing properties.It can be used for the production of medical and hygienic materials with antimicrobial properties. Chitosan wound dressings has the functions of bacteriostatic action, action for stopping pain and promoting healing in the process of wound care.
Sterile Silver Alginate Wound Dressing is a sterile, single-use dressing composed of calcium alginate and silver antibacterial agent. This highly absorbent dressing vertically absorbs wound exudate and release silver ions within the dressing in the presence of wound fluid to help reduce bacteria within the dressing. As wound exudate is absorbed, the alginate forms a gel, which assists in maintaining a moist environment for optimal wound healing and allows dead and damaged tissue removal.Based on in-vitro testing, the silver in the dressing inhibits bacterial growth in the dressing for up to seven days.View Details
