Hemostatic textiles

Key words blood clot, thrombus, coagulation cascade, hemorrhage, hemostatic textiles, wound dressing. 

Scientists in the department df chonical-fiber techncdc at the Moscow Textile Institute have few a number dF yeare b n crwiducting systematic studies d the synthesis and prej ation of new types of cellulose derivatives by applying new methods of chemical modification (mainly graft polymaizatioti). They are seeking new cellulosic materials possessii potentially useful properties, such as fire resistance, or suitable as ion-exchange, bactericidal, hemostatic and otter agents. 

Chitosan is called the last biomass of the twentieth century, and is a material that waits further development as an extraordinary biomaterial in the twenty-first century. Chitin and chitosan, derived from shellfish waste, continue to be underutilized resources. We believe that to further their development as a resource, that there are needs for products of intermediate value easy to produce and which capitalize upon the unique features of chitin and chitosan. Fibers and films based on chitin or chitosan have considerable promise for medical textile applications. The commercialization of chitosan-based hemostatic bandages, such as Hemcon , represents a significant accomplishment in gaining the acceptance of chitosan as a biomaterial. 

Bioactive mesoporous particles have also been found to have hemostatic (blood clotting) properties and have emerged as a potential rapid clotting agent for large wounds such as battlefield injimes [4]. More conventional wound healing materials tend to be in the form of fiber mats or textiles and glasses can now also be made in that form. 

New-generation medical textiles represent an important and rapidly growing field that requires functional properties such as bacteriostatic, antiviral, fungistatic, nontoxic, high-absorbent, nonaUergenic, breathable, hemostatic and biocompatible. Thus, apart from metal and metal oxide nanomaterials, nanoscale biological materials such as enzymes and drugs are required in order to add specific functionality to medical textiles [52]. Specialized nanomaterials functionalized...
