In this study, sodium chloride (NaCl) solutions with different weight pecentages (1, 3, 5 and 10 wt %) were prepared. Gauzes were impregnated with different salt loadings and samples were padded at around 100 % pick-up ratios. The samples were let dry in 130 C° for three hours and desiccated for 8 hours prior to testing. Absorption tests, wicking length tests, and Cantilever bending strength tests were evaluated. Absorption tests were evaluated according to droplet testing measurements. Wicking tests are good indicators of moisture transport in fibrous structures. Wicking length tests were only conducted in warp direction as the gauzes used as samples were narrow width woven structures. Gauzes need good absorption, good moisture transport and good pliability properties. Bending length results of impregnated gauzes were obtained from Cantilever method. The bending strength test shows flexibility with decreased bending lengths and stiffness with increased bending length values. Wicking heights increase as salt solutions have higher percentages, this might show that the samples have good moisture transport which is a necessary property in gauzes. Bending length increases with saline loading on impregnated samples and the flexibility properties of gauzes decrease as salt loading is increased. Flexibility is related to pliability and the increase in bending length is a challenge that have to be taken into account when using saline loaded bandages in wound healing as they will be stiffer.
