摘　　要：采用汽巴克隆FN双活性基活性染料对菠萝纤维进行染色,以表面得色K/S值和上染率为衡量指标,对染色温度、元明粉用量和纯碱用量等工艺条件进行单因素分析,同时分析了染料在菠萝纤维上的上染率曲线和提升性能.试验得到最佳染色工艺为:纯碱用量12 g/L、元明粉用量40 g/L、染色温度65℃.在此工艺条件下,菠萝纤维具有较好的上染率;汽巴克隆FN三原色活性染料能获得较好的拼色效果,在纤维上的提升性能也较好.Pineapple fibers were dyed with bi-functional reactive dyes of Cibacron FN. Dyeing tempera-ture, the amount of sodium sulfate, and dosage of alkaline agent were analyzed using single factor experiment and taking the K/S value and the dyeing uptake as measurement index. At the same time, the curve of the rate of dyeing and building up properties of dyes in the pineapple fibers were discussed. The optimal dyeing conditions were obtained： the amount of alkaline agent was 12 g/L, the dosage of sodium sulfate was 40 g/L, and the dyeing temperature was 65 ℃. Under the optimal dyeing conditions, pineapple fibers had higher dye-ing uptake. Good matching color effect and good building up properties on pineapple fibers could be obtained by trichromatic color reactive dyes of Cibacron FN.
