Dyeing properties of a polyester taffeta made from ultrafine fibers (0.07 denier) with disperse dyes are clarified through an analysis of sorption isotherms and rate of dye sorption data in comparison with those for microfibers (0.25, 0.32, and 0.44 denier).Ultrafine fibers are made using sea-island-type conjugate spinning techniques, while the microfibers are made by the conventional melt spinning method. Physical properties of the ultrafine fibers relating to the dyeing properties are also measured. The sorption-diffusion behavior of purified disperse dyes in the 0.07 denier (0.07d) fibers at 95°C and the physical properties of these fibers are almost the same as those of the microfibers, except
for the 0.25 denier (0.25d) fiber, which contains 0.5% additives to facilitate spinning. Therefore, ultrafine fibers can be dyed by considering only the difference in the fiber radius. Two polyester taffetas are used to measure dyeing kinetics, i.e., 0.07d fibers and
0.25d fiber

由ultra fine纤维(0.07但尼尔)制成的染特性的聚酯塔夫绸有驱散染被验证 通过一sorption等温线和染料sorption 数据的比率的分析跟那些适合microfibers(0.25，0.32，以及0.44但尼尔)比较。Ultrafine纤维使使用海岛类型结合纺技术，microfibers在常规以前挣当时融化纺方法。 与染的特性有关系的ultrafine纤维的物理性能也被测量。 那些sorption 扩散行为净化驱散在这(0.07 d)95°C 和物理性能的这些的纤维0.07但尼尔内染 除了0.25但尼尔(0.25 d)纤维，纤维几乎与microfibers的相同，这包含0.5%的附加使纺变得容易。 因此，ultrafine纤维可以通过只考虑纤维范围的差别被染。 两聚酯塔夫绸习惯于染动力学的措施， 即，0.07 d纤维和0.25 d纤维。 染料sorption的延迟 在这个开始阶段适合这0.07 d塔夫绸看得出有净化在120°C时候在95°C 和这0.07 d 和有商业染料的塔夫绸0.25 d 染。 这 现象被用在通过塔夫绸染料酒的非常慢的运动引起的个别的细丝周围的diffusional 边界层的存在方式解释。 在两塔夫绸上的商业的染料的颜色产量被讨论。
