| Popis: | Paste indigo pigment having blue colour was produced from fermentation of indigofera tinctoria leaves and twigs. Having was very popular dye and was used especially in textile industries and leather industries of fur. The aim of the study was to the optimum concentration of indigo pigmen on dyeing of suede leather. The materials used in study were crust suede leather, indigo pigmen, wetting agent, soda ash, ammonia, formic acid sulfonated oil, and redactors such as palm sugar. The dying of leather using indigo pigmen was principally similar with common dyeing and pH of indigo is 11.5, however pH on several steps must adjusted. Variation of the concentration of in dyeing was 0.5, 1, and 1.5% respectively. Performance test were of conducted for dye penetration, colour rub fastness (dry, wet), sweat resistant, and sun light resistant for 6, 13, and 20 hours respectively. The results showed that the optimum concentration of pigmen indigo was 9% dyeing and 1 % for topping with level dye, indicated appropriate penetration dye into the cross-section leather, no fading was performed by dry colour fastness test (score 4/5) and wet colour fastness test (score 4), good sweat resistant (score 5), no colour fading on the exposure to sun light for 20 hours (score 4). |
