“…Reactive dyes and alkaline and acidic dyes are commonly used in wood staining [6]; however, their usage poses persistent ecological concerns regarding chemical waste treatment [7]. Natural dyes have gained widespread recognition and research interest due to their green nature, non-toxicity, and biodegradability of associated wastewater [8].…”

Wood staining is a crucial technique for enhancing the decorative effect of wood. Different mordants and mordant processes can influence the staining effect of wood. In this study, three types of mordants and mordant methods were selected to improve the color difference and colorfastness to the washing of poplar veneer, using green peanut pigment as the dye. An orthogonal test was conducted to investigate the effects of mordant temperature, mordant time, and mordant concentration on color difference and colorfastness to washing. Range and variance analysis were employed to determine these properties’ main factors. A fuzzy comprehensive evaluation method was used to evaluate and optimize the color difference value and colorfastness of washing. The results revealed that all three factors had significant impacts on both color difference and colorfastness to washing during the process of mordant staining. The optimal process conditions (temperature, concentration, time) for achieving desirable staining effects on poplar veneer were determined as 50 °C, 0.8%, and 2 h, respectively. Furthermore, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD) analyses demonstrated that the dye formed complexes with poplar wood, enabling it to adhere to wood grain apertures and tube walls effectively. Mordant treatment increased the crystallinity of stained wood significantly while improving its overall staining performance considerably. This study provides substantial data support for future optimization processes involving natural pigment coal staining in wood.

“…A fiberboard is a type of artificial board that is made from a series of treatments, such as the gluing, heating, pressing, and sanding of raw materials. The main component is wood or plant fibers [1][2][3][4][5][6][7]. The fiberboard has three types: high-density, medium-density, and low-density types.…”

In order to expand the research on a combination of functional microcapsules and water-based coatings, antibacterial microcapsules using 3.0% sodium dodecyl benzene sulfonate as an emulsifier, self-repairing microcapsules, and photochromic microcapsules were added to water-based coatings separately or in combination and coated on medium-density fiberboard to analyze the various properties of the coating. From the perspective of the antibacterial effect, the photochromic microcapsules have little negative impact on antibacterial properties and can be used in combination with antibacterial microcapsules. When the photochromic microcapsules and antibacterial microcapsules were combined, their antibacterial rates against Staphylococcus aureus and Escherichia coli were 51.9% and 55.6%, respectively. The self-repairing microcapsules in combination with antibacterial microcapsules lead to a significant decrease in the antibacterial rate and are not suitable for use in combination with antibacterial microcapsules. From the perspective of the photochromic effect, the addition of self-repairing microcapsules can accelerate the photochromic speed of the coating, improving the photochromic effect. The addition of antibacterial microcapsules made the photochromic rate slower. Both the antibacterial microcapsules and photochromic microcapsules have weakened the self-repairing ability of self-repairing microcapsules. The width change rate in coating scratches has decreased from 21.9% to 14.7% and 17.6%, respectively. However, compared with the coating without microcapsules, the self-repairing ability still improved. The results have broad prospects in the application of antibacterial microcapsules, self-repairing microcapsules, and photochromic microcapsules for coatings on medium-density fiberboards.
