Comparisonof structure and physical properties of three kinds of medical elastic bandages
The physical properties of pure cotton,polyurethane and polybutylene terylene(PBT)medical elastic bandages,such as surface morphology,mass per unit area and thickness,elastic property,bending property,hydrophilic property and liquid diffusion property are tested and compared.The results show that among the three kinds of elastic bandages,pure cotton and PBT elastic bandages are plain fabrics,while polyurethane elastic bandage is provided with a warp-rib structure.PBT elastic bandage possesses the smallest mass per unit area and thickness,the best stability,softness and comfort,and has good elasticity,elastic recovery,excellent hydrophilic and liquid diffusion properties.
