Crust leather quality with eco-printing dyeing method

Received Date:01 November 2021, Accepted Date:01 January 2021, Published Date:13 January 2021


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 <0.05) on wet rubbing resistance, sweat resistance, andwashing resistance. Therefore, the crust leather soaked in the mordant of Aluminum potassium sulfate for 36 hours before being dyed using the ecoprinting method did not show any decrease in its physical quality. It even showed some improvements of wet rubbing resistance with the value of 4 and 5, sweat resistance with the value of 4, and washing resistance with 4 to 5. Novelty/Applications: Natural dyeing using the eco-printing method can be applied to sheep crust leather to improve the quality of wet rubbing resistance, sweat resistance, and washing resistance. It is also recommended that crust leather be soaked in Aluminum potassium Sulfate’s mordant solution for 36 hours.
