Pinus sibirica L., known as Siberian pine, belongs to the family Pinaceae and is a species of pine tree that grows in Siberia. It is planted mostly in parks and large

gardens as an ornamental tree. The barks and shells of the Siberian pine are rich in valuable biologically active compounds such as phenolic compounds and

natural dye content. In contrast to other natural dye sources, there has been very little information on the dyeing properties of Siberian pine and up to our

knowledge this is the first study about dyeing of double face and lining leathers with Pinus sibirica L. extracts. In this study, dyeing characteristics of double

face and lining leathers with the extracts of Pinus sibirica L. obtained by different extraction methods such as alkali, ultrasound and conventional was

investigated in terms of color measurements, rubbing fastness, antimicrobial effect, and shrinkage temperatures. The extraction yield (%) of the extraction

methods was also calculated. The dyeing characteristics of the Siberian pine extracts was evaluated with Minolta CM-3600A spectrophotometer and to-and-

fro rubbing fastness test was performed according to TS EN ISO 11640 standard. Agar diffusion test method was used for the determination of antimicrobial effect and ISO 3380 was followed for providing the shrinkage temperature values. The results of the study revealed that Siberian pine extracts could be used as a natural biocomponent and applied successfully in double face and leather dyeing processes to produce eco-friendly leather goods.
