This research was carried out to find the mordant effect of Chestnut's inner skin on the cow leather dyed by Turmeric powder. The best proper mordanting conditions were examined by changing mordant method, concentration, temperature, bath ratio, time, and repetition. Also dyeability and surface color changes were evaluated by various mordanting methods. The optimum mordanting conditions of chestnut's inner skin extract on the cow leather were pre mordant, 80%, 50℃, 50:1, 40minutes, 4 repetition. The K/S values as a mordant were higher in pre mordant than post mordanting condition. Although the ΔE was slightly higher in post mordant than pre mordant, it was too small to find any means. The surface colors of all dyed cow leathers were yellow. Among light, dry cleaning, and abrasion fastnesses, only light fastness was increased one degree, others were same degrees.
