Application of Forest By-Products in the Textile Industry: Dyeing with Pine and Eucalyptus Bark Extracts

Abstract

The main by-product generated in the forestry industry is bark, derived from the debarking process. Pinus and eucalyptus are nowadays two of the most important tree species exploited by the forestry industry in southwestern Europe. This work investigates the application of Maritime pine (Pinus pinaster Ait.) and Eucalyptus (Eucalyptus globulus Labill.) barks as a source of high polyphenolic content extracts, to be used as natural dyes in the textile industry. We demonstrated that it is possible to use the extracts obtained from both forest by-products as textile dyes without the need for using any metallic mordant.
