Crust leather quality with eco-printing dyeing method

Background/Objectives: The eco-printing method is a dye transfer process that produces natural shapes of leaves and flowers on sheep leather. research objective aimed at determining the quality crust leather using method. Methods/Statistical analysis: applied experimental sixteen sheets study employed completely randomized design. treatments involved soaking in mordant alum solution with several times, namely (T0) = 0 hours, (T1) 12 (T2) 24 (T3) 36 hours; each was repeated four times. variables included wet rubbing resistance, sweat washing tear strength, elongation, seam strength. data were analyzed anova. Findings: results showed time did not significantly affect (P> 0.05) However, it had significant effect (p <0.05) andwashing resistance. Therefore, soaked Aluminum potassium sulfate for hours before being dyed ecoprinting show any decrease its physical quality. It even some improvements resistance value 4 5, 4, to 5. Novelty/Applications: Natural dyeing can be improve also recommended Sulfate’s hours. Keywords: Crust; ecoprinting; leather; quality;
