| 摘 要： | 用分散红FB分别对涤锦复合超细纤维（A）、涤纶海岛超细纤维（B）和普通涤纶纤维（C）进行染色，得出扩散系数D、半染时间tv2等染色动力学参数，结果表明：涤锦复合超细纤维的上染量随时司的延长而增加，染料对纤维的吸附速度随温度的升高而增快、由于锦纶组分的存在，在相同染色温度下，涤锦复合超细纤维的染料吸附量比涤纶纤维少，其扩散系数随着温度的升高而增大，至一定峰值以后逐渐变小，而且随tv2的增大而变小，但这种反比关系不及涤纶超细纤维和普通涤纶纤维明显．

| Abstract: | PET/PA composite micro-fiber(A),PET sea-island micro-fiber(B) and common PET fiber(C) were dyed resp.with disperse red FB to obtain the dyeing dynamical parameters such as diffusion coefficient D and half dyeing time t1/2.It was shown from the results that the dye pick-up on A increased with increasing the dyeing time,and the dye adsorption speed increased with increasing the temp.The A fibers adsorbed less dye than the PET fibers at the same dyeing temps.because of the presence of the PA component.The D values increased with increasing the temp.,and decreased after reaching the peak values.The D values increased as t1/2 increased,but such a relationship was less marked than B and C fibers. |
