Adding Value to Maple (Acer pseudoplatanus) Wood Furniture Surfaces by Different Methods of Transposing Motifs from Textile Heritage

Abstract

The present paper is part of an ongoing research project carried out to find methods to transpose traditional motifs from Romanian textile heritage to furniture ornamentation, as an additional method of preserving the motifs besides conventional conservation. Modern technology, such as Computer Numerical Control (CNC) routing or laser engraving can revive furniture ornamentation, eliminating manual labor and long execution time. Three methods were applied to transpose a bicolored motif from a traditional Romanian blouse from Transylvania onto the surface of maple wood furniture. The first method utilized was nitrogen laser engraving, in which ten power settings between 10 W and 150 W were applied and color measurements were carried out on the resulting engraved surfaces. Following the International Commission on Illumination (CIELab) system analysis, two laser power settings were selected to engrave the ornament on a maple wood surface for an accurate reproduction. The second method employed a staining solution applied on flat wood surface, followed by routing the model on a CNC machine and further coating with lacquer. The third method consisted of CNC routing the model on the wood surface, then coloring the engraved ornament followed by surface sanding to remove color from the flat wood surface and, finally, lacquering. The ornaments transposed onto maple wood surfaces were aesthetically assessed, the technologies were analyzed, and the details of the processed ornaments were highlighted by Stereo Microscope investigation. The conclusions showed that each method adds value to the wood surface by original ornamentation and can be applied as furniture decoration.

Influence of Irradiation Parameters on Structure and Properties of Oak Wood Surface Engraved with a CO2 Laser

“…With grading the laser power and raster density, the total colour difference values were far beyond 12, corresponding, in accordance with the reported scale, to the total new colour compared to the original. Qualitatively, these changes were like the ones reported by [ 10 , 11 , 16 , 20 , 24 ]. Quantitatively, our results were different, as we studied discolouration on different wood species and under varying laser parameters (head movement rate, focal distance and similar).…”

“…The technology of material treatment using laser irradiation has met a wide range of applications in cutting and surface treatment of metallic and non-metallic materials, including wood and wood-based ones [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. At present, considerable attention is devoted to studying the performance of surfaces engraved with CO 2 lasers, aiming for purpose-oriented changes to wood structure and properties [ 6 , 8 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ].…”

The Effect of CO2 Laser Engraving on the Surface Structure and Properties of Spruce Wood

“…These colour modifications corresponded to the changes in spruce wood chemical structure, discussed in the previous chapter. These qualitative changes are in line with those previously reported [4,7,8,[19][20][21][22][23][24]33]. Our results quantitatively differ from the earlier results, given the different wood species examined and the different laser parameters set.…”

“…The changes in the colour coordinate values, L*, a* and b*, are relatively easy to measure and, as such, they can serve as indicators of significant chemical changesand changes in other wood properties-resulting from a specific surface treatment (IR radiation, UV radiation, thermal modification and similar) [29]. This is the main reason for the interest in this issue today [6,8,13,15,25,26,[30][31][32][33].…”

Research on color and texture characteristics and visual perception of custom wardrobe finishes

“…The color moments and color histogram data of beech wood sample images were calculated, and the feature vector set was divided into different clusters for color classification using the K-means algorithm, completing the color classification and texture recognition of beech wood samples. Lungu et al (2022) employed three methods to transfer the two-color patterns from traditional Romanian shirts of Transylvania onto the surface of maple furniture, confirming its applicability for furniture decoration. The study on furniture surface decoration currently focuses more on craftsmanship research rather than the performance aspects.…”
