In order to design and develop new medical non-woven bandages,polyester and viscose were used as raw materials to prepare non-woven bandage base fabrics with different raw material ratios and different treatment processes.The surface morphology of non-woven bandage base fabrics was observed,and their thickness,air permeability,tensile property,bursting property,bending property,hydrophilic property and liquid diffusion property were tested and analyzed.The results show that the 60%viscose/40%polyester semi-cross-layed non-woven bandage base fabric and 100%polyester semi-cross-layed non-woven bandage base fabric after sizing have better comprehensive properties.The former has a flexural stiffness of 0.24 mN·cm,a air permeability of 551 mm/s,and a elongation at break of 51.60%.The latter has a air permeability of 601 mm/s and a elongation at break of 83.94%.Both of the two are suitable for making medical non-woven bandages.
