Abstract

This paper investigated to the effectiveness of an eco-friendly method for oiling cow leather. After leather was lac-dyed with a vegetable leather processing solution and a mordant, olive oil was used to treat the leather. Changes in surface color and dyeability, light fastness, rubbing fastness, and water fastness were measured. An increase in dyeability caused by the mordant appeared in all the samples. The dyeability of leatger treated with Cu-mordant was higher than that treated with Fe-mordant and Al-mordant, and the three times greater than when no mordant was used. Dyeability after oiling more than doubled compare with before oiling. An increase in dyeability by oiling was highe greater than doubled compared with before oiling. The non-mordant-treated samples exhibited a 5-fold increase in dyeability, and the other samples showed more than two times more dyeability than did non-oiled samples. A color difference of more than 20.0-fold appeared in all samples, and the differences in lightness and chroma were greater than were the differences in other color factors. The colors after oiling were measured R, P, and PB. Light fastness improved in all samples after oiling, and all of the measurements were reduced in the order of Fe-mordant> Cu-mordant> Al-mordant ${\geq}$non mordant.
