Abstract :
In this study, the potentiality of using the organic dying material obtained from the tea plant extracts in the wood protection industry is analyzed and the total retention (Kg/m^3), retention %, and upper surface processing (hardness) in wood is determined. Natural coloring agent in the world and in Turkey soft drink consumed in tea, that ocur during the processing of the extract was obtained as waste tea according to ISO 9768 standards. For this purpose, developed the tea dye as surface coating material and double component waterborne varnish were applied on the wood surfaces such as pine (Pinus silvestris L.), beech (Fagus orientalis L hardness changes values are calculated. According to experimental results, , the highest retention rate belongs to Beech wood (6.75 %), the lowest to scotch pine (5.61%). The total value of highest retention belongs to Beech wood (100.65 kg/m^3) and the lowest to scotch pine (68.18 kg /m^3) were obtained. The highest value of hardness change water based varnish (37.60) beech wood is obtained, at least the value of hardness change (17.60) tea dye was beech wood.
