Rabbit skin as a by-product has potential value in producing fur skin for making hats, clothes, wall hangings, bags, upholstery for household furniture. Fatliquoring is one of the final operations of post tanning process that influenced the physical characteristics on fur leather. Egg yolk is suitable as fatliquoring agent because it contains a natural emulsifier (lecithin) which works as an emulsion stabilizer so that the fat can be penetrated into the collagen fibers perfectly. This study aims to determine the effect of utilize egg yolk as a fatliquoring agent in rabbit fur tanning. Egg yolk was used as a fatliquoring agent, with concentrations of 8, 10, and 12%. The concentration of egg yolk as a fatliquoring agent affected the physical properties of the rabbit fur leather. Increasing the concentration of egg yolk can increase the tensile strength, elongation, sewing strength, and tear strength significantly. This rabbit fur leather suitable to use as gloves.
