    Color fixation mechanism of CTS-Ag and its effect on the properties of dyed veneer

    • 摘要: 通过分析pH值对CTS-Ag与酸性染料反应产物的性能影响,揭示CTS-Ag的固色机理。采用不同抗菌染色工艺制备抗菌染色薄木,分析其颜色、耐水性、耐光性以及防霉抗菌性能。结果表明:CTS-Ag与酸性染料能在酸性条件下发生酸碱中和反应,酸性越强,染料的上染率越高,固色效果越好;抗菌染色薄木与直接染色薄木之间的色差,工艺B>工艺C>工艺A;抗菌染色薄木的水洗色牢度,工艺C>工艺A>工艺B;工艺A制取的抗菌染色薄木的日晒色牢度变差,工艺B、C制取的抗菌染色薄木的日晒色牢度得到改善;抗菌染色薄木的抗菌防霉性能,工艺A>工艺C>工艺B。

       

      Abstract: We analyzed the effect of pH value on the properties of reaction products between CTS-Ag and acid dyes in order to optimize the processes of antibacterial dyeing veneers and reveal the color fixation mechanism of CTS-Ag. The chromatic aberration, water fastness, light fastness, and antibacterial property of antibacterial dyed veneers with various processes were measured. The results showed that: an acid-base neutralization reaction occurred between CTS-Ag and acid dyes under acid condition, and the lower pH value,the higher value of dye uptake rate and better fixing effect. Chromatic aberration value between CTS-Ag-treated antibacterial dyed veneer (ADV) and untreated ADV ranked as: ADV pretreated with CTS-Ag (Process B)>combined treated ADV (Process C)>post-treated with CTS-Ag (Process A). For water fastness, the order was Process C>Process A>Process B. However, Process A presented a poorer light fastness, while Process B and Process C improved light fastness. For antibacterial and antifungal properties, the order was Process A>Process C>Process B.
