摘　　要：通过正交试验考察染液质量分数、染色时间、染色温度和促染剂用量对染透率、上染率和色差的影响,利用极差分析和方差分析确定各因素的影响程度及各指标的最优工艺参数;在此基础上利用模糊数学综合评判法对3个指标进行综合评价,对染色工艺进一步优化.结果表明:染液质量分数和染色温度对染透率和上染率的影响显著,但各指标单独优化得出的工艺参数不一致;通过模糊数学综合评价获得染透率、上染率和色差效果最优的染色工艺,即染液质量分数2.0%,染色时间4 h,温度90℃,促染剂用量3.0%.在此条件下染透率、上染率和色差分别可达53.64%、7.59%和53.20,总体高于正交试验中各指标最大测试值,说明该方法合理、可行.To optimize the dyeing process of Chinese fir wood treated with acid scarlet 3R,an orthogonal experiment concerning dye mass concentration,dyeing time,dyeing temperature and accelerant dosage were conducted.Dye penetration rate,dye uptake rate and color difference of the products were evaluated by range analysis and variance analysis to evaluate the impacts of dyeing settings on optimal product.Fuzzy comprehensive evaluation was further conducted on product indicators to determine the optimal process parameters.The results showed that dye mass concentration and dyeing temperature had the greatest effects on dye penetration rate and dye uptake rate,but the product parameters varied when the 2 process factors were applied at optimal levels,respectively.Based on fuzzy comprehensive evaluation,the optimal dyeing process was to use dye solution at mass concentration of 2.0%,dye for 4 h at 90℃,with the assistant of 3.0%dyeing accelerant.Under the optimal conditions,the dye penetration rate,dye uptake rare and color difference of the dyed wood reached 53.64%,7.59%and 53.20,respectively,exceeding the maximum testing values when each factor was at the optimal level in the orthogonal experiment,implying the rationality and feasibility of the processing setup.
