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. The research objective aimed at determining the quality of sheep crust leather using the eco-printing method. Methods/Statistical analysis: The research applied the experimental method using sixteen sheets of sheep crust leather. The study employed a completely randomized design. The treatments involved soaking the crust leather in a mordant of alum solution with several soaking times, namely (T0) = 0 hours, (T1) = 12 hours, (T2) = 24 hours, and (T3) = 36 hours; each of the treatments was repeated four times. The research variables included wet rubbing resistance, sweat resistance, washing resistance, tear strength, elongation, and seam strength. The data were analyzed using anova. Findings: The results showed that the soaking time did not significantly affect (P> 0.05) on tear strength, elongation, and seam strength. However, it had a significant effect (p
