Abstract:
The aim of this study was to utilise the Nile perch fish skins which are usually a waste from fish
filleting companies to make leather and then to determine its physical properties. The skins were
processed into leather using chromium(III) sulphate. The physical properties of leathers were
determined using standard IUP methods which include: Tensile strength, Tear strength, Flexing
endurance, Shrinkage temperature, Grain crack and Grain burst tests.
The results demonstrated that the tensile, tear strength and elongation of the leather varied
depending on the direction and location of the collagen fibres. The properties of the Nile perch leather
were satisfying enough for the material to be used in the manufacture of high grade leather products.
The study showed that the fish skins can supplement sources of raw materials in the leather industry
and reduce the environmental pollution caused by disposing of the skins to the environment.
