The water soluble hemostatic textile materials, which have biologically hemostatic activity, are chemically processed from delipided cellulose. In this paper, the effect of these materials on platelet and thrombus formation is studied. These hemostatic textile materials can form colloidal particles in liquids, absorb activated platelets and take part in hemostasia. The platelet adhesion rate of these materials is about 50%. The thrombus formation test outside the body showed that S 99 and S 100 hemostatic...
