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.
