Dyes and pigments offer significant potential for functional and aesthetic design of leather materials. Search for viable alternative leather colorants, which have the potential to develop new creative designs and provide functionality are presently in focus. In this context application of alternative textile dye substances that can offer special effects to leather have increasingly gained importance. In this study, the potential application of ink dyes in leather industry was investigated as an alternative to conventional dyes for the production of leathers with high fastness properties. For this purpose, leather dyeing recipes were developed by using two different ink dyes including latex and dye based ink dyes and applied at dying process of metis type crust leathers in order to produce high performance leathers. The quality performance of dyed leathers were investigated in terms of colour measurements, to-and-fro and crockmeter rubbing fastness, before and after washing leathers in a washing machine under specified conditions according to ISO 15702 standard. The colour measurements prior and subsequent to washing process were determined with Minolta CM-3600A spectrophotometer. To-and-fro rubbing and crockmeter fastness properties were examined in accordance with TS EN ISO 11640 and ASTM D5053 standards respectively. The results of the study showed that latex and dye based ink dyes could be used as a newly adapted dye group and applied successfully in leather dyeing process for the production of leather goods with high fastness properties.
