| 摘 要： | 泡桐是我国重要速生人工林树种,采用价格低、色谱全、来源广、渗透性和化学稳定性好的活性染料对其进行染色可实现泡桐资源的高效利用。通过分光光度法测定染色前染液、染色后残液(合并清洗液)的分光光度值,计算出活性染料对泡桐单板染色的上染率,以上染率为考察指标,选取染色温度、染色时间、促染剂用量及固色剂用量4个因素,作极差分析得到:染色温度是活性染料对泡桐单板上染率影响最大的因素,其次是促染剂用量、染色时间和固色剂用量。较优工艺条件:染色温度为70—80℃,染色时间3h,促染剂元明粉40g/L,固色剂纯碱20g/L。 |

| Abstract: | Paulownia is an important fast-growing plantation tree,and efficient utilization of paulownia can be achieved through coloration with active dyes,which are low price,wide chromatogram,easily obtained,superior penetration and chemical stabilization.Before and after dyeing,absorbance values of dye liquor and remaining dye liquor(combining cleaning fluid)were determined,and dye uptake of active dyes for the veneer of paulownia were calculated.Dyeing orthogonal tests were conducted to study 4 factors of dyeing ... |
