摘要
采用不同种类固色剂对染色桦木单板进行后处理,探讨其对染色单板表面耐水颜色稳定性的影响。结果表明:6种金属盐中,用KAl(SO4)2浸泡处理,综合固色效果最好;Na2SO4等其他5种的固色效果较差,不适用于固色。与KAl(SO4)2、固色剂Y相比,单板染色后涂刷壳聚糖,能有效提高耐水颜色稳定性,且颜色均匀,固色效果最佳。
Veneer, dyed by acid dyes, easily fades because of its poor color fastness to water. In order to improve the color fastness to water, the veneers(Betula spp. )were treated with different color fastening agents after dyeing, and the influences of the different agents to the dyed veneer were investigated in this paper. The results proved that the veneer dyed with the color fastening agent of KAI(SO4)2, compared with other five mineral salts such as Na2 SO4, CuSO~, etc. , had advantages of small color variation and excellent color fastness. The veneer treated by fastening agent Y could also gain a good effectiveness but was not environmentally-friendly. The effectiveness of veneer coated by chitosan after dyeing was the best among those treated with KAI(SO4)2 and fastening agent Y, respectively, that not only had small color variation but considerably improved the stability of dyeing.
