The quality of a raw material for any manufacturing industry or firm is one of the decisive factorsrncontrolling its productivity and profitability. Leather processing industries are no exceptions tornthis fact. The decline of quality raw material supply for the leather processing industries is a greatrnchallenge to be competent and survive in the industry these days. The quality of the raw materialrnis largely affected by different factors. The problems leading to lower selection of raw skins orrnsemi-processed skins in industry are categorized as ante-mortem and post-mortem defects.rnEspecially the ante-mortem defect caused by ecto-parasite attack on the skins surface is one of thernmajor problems for downgraded selection of sheep and goat skins. In this research work, anrnattempt has been made to upgrade poor and reject wet blue leathers due to mange disease damagernor â€œEkekeâ€ on sheep skin. The problem of lower quality selection of skins could be improved andrnupgraded into better quality shoe upper leather by working on suitable leather processingrntechniques for covering the defects of mange damaged skins in wet-finishing and finishing byrnupgradation and optimization. In wet- finishing process, filler waxes and pigments combinationrnwere employed for upgradation. This has resulted in improved coverage of defects on dyed crustrnleathers. Physical strength tests and organoleptic property assessments performed on the treatedrnleathers are found to be good. The optimized process of dyed crust leather is taken further forrnfinishing, where five finishing methods were chosen for upgrading the uncovered defects in wetfinishing.rnrnWaxy, metallic, corrected grain and cationic finishing were employed against thernconventional resin finishing. With cationic finishing, an improved and upgraded leather wasrnobtained with better natural look or appearance of grain, good covering and comparable physicalrnand organoleptic properties and better grade.
