C6-oxidized regenerated cellulose

as a hemostatic material

its physic-chemical properties affect the hemostatic performance. To research the properties of oxidized regenerated cellulose with different three-dimensional structures and oxidation degree

we compared their water absorption

gelation rate

dissolution rate

degradation rate

ageing resistance

hemostasis effect. It was found that

with the increase of oxidation degree

oxidized regenerated cellulose has stronger water absorption

faster gelation rate

dissolution rate and degradation rate

but weaker ageing resistance

shorter lifetime. The mesh and porous structure of the fiber

compared with the compact structure of the gauze

is more advantageous to increase water absorption

speed up gelation rate and dissolution rate

meanwhile reduce the usage amount of the oxidizing agent and improve the ageing resistance. Fiber has faster hemostasis speed and better hemostasis effect than gauze in the same condition of oxidation degree.
