Evaluation of the Dyeing Properties of Basswood Veneer Treated by Dichlorotriazine Reactive Dye Based on Gray Correlation Analysis

Abstract

The dyeing properties of basswood veneer treated by dichlorotriazine reactive dye in a dip dyeing method were evaluated. The effects of dye concentration, dyeing temperature and time, volume ratio, and dyeing agent were observed relative to the dye-uptake and K/S, using gray correlation analysis. Results showed that various dip dyeing factors had remarkable influences on dye-uptake and K/S, especially dyeing temperature and volume ratio. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX) results indicated that reactive dyes were successfully combined with basswood and diffused into the wood fiber lumens and ray cells. Furthermore, thermogravimetric analysis (TGA) demonstrated that the residue of dyed veneer was higher than undyed, and the temperature at maximum degradation rate of dyed and undyed veneer was different.

Evaluation of ultrasonic-assisted dyeing properties of fast-growing poplar wood treated by reactive dye based on grey system theory analysis

“…The dye used in this study belongs to a low temperature dye; therefore, the molecule activity of dye was reduced by the relatively high temperature of the solution. In addition, the hydrolysis rate of the dye was higher than the rate of its reaction with wood fiber [4]. K/S demonstrates a similar tend between 20 and 70 °C.…”

“…The absorption at 1740 cm −1 was due to C=O stretching of xylan [37]. The peak at 1034 cm −1 was attributed to C-O-C stretching of aliphatic ether bond [4]. In comparison with the undyed wood, the -OH band was broader in the case of dyed wood, which could be caused by different types of inter-and intramolecular hydrogen bonds [38,39].…”

“…The alkaline agent selected as fixing agent could enhance dye uptake [35]. Different amount of fixing agent was added, and the results of its effects are presented in Fig.…”

“…However, the tone is relatively bland, and the superficial color is variational, which leads to the reduced aesthetic value for fast-growing wood. Wood dyeing, an advanced and mature technique, can eliminate color differences, simulate the color properties of highly valuable wood species, and improve the visual characteristics of wood products [3,4]. The dyed wood products have been widely applied in furniture, flooring, interior decoration, and sports equipment, etc., and generated tremendous social and economic benefits [5][6][7].…”

Weathering performance of dyed bamboo fiber composites

“…Wood dyes may be based on either water or alcohol (e.g. ethanol) solutions, and these may be neutral, acidic or basic (Li et al 2011;Jamili et al 2019;Hu et al 2016). Based on preliminary work (Hu et al 2014), dying bamboo fiber bundles with acid-based dye produced acceptable color and luster but had reduced color penetration and uniformity.…”
