Abstract

The leather finishing process is the final stage in the leather tanning process, which makes the leather look attractive and comfortable. One of the leather finishing processes can be done using the ecoprint coloring method.  Exposure to excessively hot temperatures can cause several types of damage to the tanned leather, it can make the tanned leather stiff and lose its original flexibility. This research aims to obtain the best quality ecoprint leather at different temperatures and boiling times. Boiling is carried out at temperatures of 60˚C, 70˚C, 80˚C and the boiling time is 1.5 hours and 2 hours. Leather quality is measured by tensile strength, sewing strength, tear strength, leather elongation, and color fastness to wet and dry rubbing. The interaction between temperature and boiling time has a significant effect (P>0.01) on the quality of ecoprint leather, namely tensile strength, sewing strength, tear strength and color fastness from dry and wet rubbing. The best quality ecoprint leather is boiled at a temperature of 70 ˚C for 2 hours.
