Abstract
Background/Objectives: In this study, we compared and analyzed the dye ability of oak-patterned materials with acid dyes, and evaluated their performance as interior materials. Use of processed timber can help reduce environmental damage and the economic burden of resources (important problems with use of raw timber) and can meet the needs of various fields where the sensibility of raw timber is required. Veneer wood is positioned as a high-value-added product due to its luxury and beauty, and it is used in various fields as a building-related material, such as interior decoration, furniture, flooring, building interior materials, and lumber. Dyeing is necessary to enhance the aesthetic appearance of this pattern and to expand its use.
 Methods: As the wood used in the experiment, American red oak, which has marketability in the market, was selected. The spectral reflectance of each wavelength band was measured using spectrophotometer to evaluate the apparent concentration and dyeability of the dyed and fixed samples. Durability was evaluated by measuring rubbing and light fastness.
 Results: The oak pattern was dyed with 3 types of acid dyes and a comparative analysis was performed. The most suitable conditions are 95℃, 3 hours, and 3% o.w.f. In addition, evaluating resilience to daylight fastness, resilience to rubbing, fire resistance, and flame retardance, yielded results suitable for use as an interior material.
 Conclusion/Implications: It was confirmed that veneer can be dyed with acid dyes and used. It is hoped that this study will be used as basic data for dyeing veneer with acid dyes and synthetic dyes in the future. The results of this research are expected to contribute as basic data for the dyeing process of synthetic dyes.
