本文采用酸性大红染料对木材进行染色试验 ,以染液组成和染色工艺为试验因素 ,用正交方法对木材色差和上染率进行观测和分析。试验结果表明 ,Na Cl是使泡桐单板染色色差增加的第一作用因素 ,最佳浓度是 1 .5%。处理温度是第二作用因素 ,50℃的温度对色差和上染率都是有利的。表面活性剂是第三作用因素 ,最佳浓度是 0 .1 %。最佳染色时间 4 h,作用因素居第四位。乙酸最佳作用浓度 2 % ,是第五作用因素。染料浓度变化对色差没有造成明显的变化 ,染料浓度 0 .5%时上染率最高 ,染料利用率也高 ,该因素对色差的作用居最末位
In this paper, acid red dye on the wood dyeing test, the dye composition and dyeing process as the experimental factors, using orthogonal method to observe and analyze the wood color and dye uptake rate. The results showed that NaCl was the first factor to increase the chromatic aberration of paulownia wood, the best concentration was 1.5%. The treatment temperature is the second factor, and the temperature of 50 ℃ is good for both color difference and dye uptake rate. Surfactant is the third factor, the best concentration is 0.1%. The best dyeing time 4 h, the fourth factor in the role. Acetic acid best concentration of 2%, is the fifth factor. Dye concentration changes did not cause significant changes in color, dye concentration of 0.5%, the highest dye uptake, dye utilization is also high, the role of the factor of the final home living
