Abstract: A hemostatic textile material to stop bleeding comprising a dialdehyde cellulose (DAC) carrier wherein the degree of oxidation of the dialdehyde cellulose varies from about 1.5% to 12%; and a blood coagulation factor selected from the group consisting of chitosan and gelatin; the blood coagulation factor being chemically immobilized thereon; and further optionally comprising a bacteriolytic agent selected from the group consisting of a lysozyme enzyme, silver nitrate, and chlorhexidine; and further optionally comprising a selected component that prevents hemolysis, the component selected from the group consisting of tranexamic acid or ?-aminocaproic acid chemically immobilized thereon.

Abstract: The invention provides a method for preparing a wound dressing, comprising activating a textile carrier to form between about 0.026 and 0.06 mg-equiv. of aldehyde groups per gram of carrier, impregnating the activated carrier in a solution of at least one bioactive enzyme and drying the same, whereby there is produced a wound dressing from which the bioactive enzyme is releasable in effective amounts for a period of at least 3 days upon the dressing being brought into contact with a moist surface.
