摘　　要：为了探究构皮纤维的上染性能,采用两种工艺对构树韧皮进行化学脱胶,选用活性红KN-3B染料对脱胶后的构皮纤维进行染色。研究两种工艺脱胶后的构皮纤维的染色动力学,包括上染速率、半染时间、上染百分率和扩散系数等参数,并与普通汉麻纤维进行了比较。结果表明:采用二道碱煮法脱胶工艺制得的构皮纤维上染百分率达到26.67%,上染速率、染色扩散系数和半染时间都明显优于另一种工艺;对比汉麻纤维,各项数据表明二道碱煮法脱胶工艺所得构皮纤维与现存成熟工业化生产的汉麻纤维的染色性能较为接近,说明该脱胶工艺下构皮纤维染色性能较好。In order to explore the dyeing performance of the paper mulberry bast fiber,two processes were used for chemical de-gumming of the paper mulberry bast fiber,and the reactive red KN-3B dye was used to dye the paper mulberry bast fiber.The dyeing kinetics of the degummed bast fiber by the two processes were studied,including the dye uptake rate,half-dyeing time,dye uptake percentage and diffusion coefficient,and compared with ordinary hemp fiber.The results showed that the dye uptake rate of the bast fiber prepared by the two-stage alkaline degumming process reached 26.67%,and the dye uptake rate,dyeing diffusion coefficient and half-dyeing time were significantly better than the other process.Compared with hemp fiber,all the data showed that the dyeing performance of the paper mulberry bast fiber obtained by the two-stage degumming process was close to that of the existing mature industrial hemp fiber,indicating that the dyeing performance of the bast fiber under this degumming process was better.
