SOLUBLE HEMOSTATIC GAUZE AND PREPARATION METHOD THEREOF

摘要

Disclosed is a soluble hemostatic gauze prepared by carboxymethylated solvent spun cellulose fiber. Also disclosed is a method for preparing a soluble hemostatic gauze, the method comprising: using sodium hydroxide solution and sodium chloroacetate solution separately or simultaneously to basify and etherify solvent spun cellulose fiber. A carboxymethylcellulose fiber having high clarity, a high degree of substitution and high hydroscopicity which is used for preparing a soluble hemostatic gauze can be obtained at a lower temperature using the method.
