Color Difference of Natural Dyed- and Finished Veneers by Fading Test

In order to evaluate a feasibility of industrial art use of veneer such as cylindrical laminated veneer lumber, the veneers of 4 species of Korean pine, radiata pine, yellow poplar and Japanese cypress were natural dye-colored and clear finished. Natural dyes were red color originated from sappanwood, blue color from polygonum indigo, and yellow color from Amur cork tree and gardenia. the clear coats of crack seal clear and UV protection oil were applied on the dyed veneer. The dyeing and finishing characteristics through fading test were summar-ized as follows; In non-dyed and non-finished Korean pine veneer, lightness was decreased and yellow and red hues increased after fading test. In natural dyed- and finished- veneer, color dif-ference of gardenia-mixed Amur cork tree was generally highest, and that of polygonum indigo was lowest. Compared to non-treatment of veneers of Korean pine and yellow poplar, color dif-ference decreasing effect by finishing was shown in crack seal clear and UV protection oil. In addition, UV protection oil was more favorable than crack seal clear with more decreased color difference. In result, maximum values of color difference after fading for 8 days were recorded about 16 to 20, which are remarked ‘very much’ of 12.1 or more when reviewing with ‘National bureau of standards unit in USA’.
