Investigation mordanting method to enhance of holding naturel dyes on wood material

Some studies have been made on the application and strength of natural dyes to wood materials. According to these studies, applying natural dyes to wood material has some disadvantages. One of these disadvantages is partially leaching of dyed wood with natural dyes. The aim of this study is to determine which mordanting method is effective to solve the leaching problem of natural dyes applied on wood material. In this context; hibiscus (Hibiscus sabdariffa L.) has been chosen and its extractions were applied by three methods: pre mordanting, post mordanting and simultaneously mordanting on Yellow Pine (Pinus sylvestris L.), Chestnut (Castanea sativa Mill.) and Mahogany (Khaya ivorensis) wood test samples by immersion methods. Iron sulfate, aluminum sulfate and vinegar were used for mordanting. As a result of experiments; minimum leaching was determined on wood samples that applied with post mordanting method.
