Hybrid Decorative Elements Inspired by Textile Heritage for Furniture: Design and Influence of Coating on the UV-Accelerated Aging Behavior

Vollständiger Abstract

Worum geht es in dieser Arbeit?

Integrating traditional textile heritage into contemporary furniture design offers an innovative way to preserve cultural identity through modern materials and decorative techniques. This study investigates the color stability of hybrid decorative plywood panels fabricated using mechanical perforation and sewing techniques inspired by traditional textile motifs. The samples were evaluated using UV-induced artificial aging, alongside color measurements before and after exposure, microscopic analysis, and Fourier Transform Infrared Spectroscopy (FTIR). The approach enables traditional decorative patterns to be transferred onto wood-based materials, creating contemporary furniture decorations, while preserving and reinterpreting the textile heritage. Results revealed distinct aging behaviors depending on the finishing system. Changes in total color difference (ΔE*)—4.36 for red thread, 4.21 for unvarnished reference, 3.34 for oiled, 0.72 for water-based, 2.55 for nitrocellulose-based, and 0.52 for epoxy-coated samples—demonstrated that both the coated plywood substrate and the textile thread were affected by aging after 72 h of UV exposure. Epoxy resin and water-based coatings provided the greatest color surface stability, while oil- and solvent-based finishes exhibited varying degrees of chromatic alteration due to their different responses to ultraviolet radiation and moderate temperature. The stitch technique showed good structural compatibility with plywood and preserved the integrity of heritage-inspired motifs after artificial aging for 72 h of UV exposure relative to long-term furniture use, which is a limitation of the present study. However, the red cotton sewing thread was more sensitive to light exposure, showing a slight UV-induced discoloration, with effects varying according to coating type. FTIR investigations demonstrated that UV aging of the cotton thread resulted in some photo-oxidative degradation of cellulose, which may explain the minor incipient microstructural degradation phenomena observed by SEM.
