Abstract
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.关键词
