摘要
溶解度参数δ是热力学上衡量非极性溶质与溶剂之间作用力的一种方法,将其用于分散染料对PET聚酯纤维染色中,通过计算PET的δ为10.30~11.6之间,与分散染料有很好的相容性,因此染色性能与牢度性能俱佳。将该方法用于分散染料拼混和染厂拼色,可获得极佳效果。PTT聚酯的δ值为10.50,也可用传统分散染料染色。PLA纤维是一类脂肪族聚酯纤维,性能与PET、PTT不同,其δ值为12.8,传统分散染料达不到很好效果,需研发PLA专用分散染料。
Solubility parameters 8 is a thermodynamical parameter to evaluate the action between nonpolar solute and solvent. The 8 value of PET fiber is 10.30 - 11. 6, so it has good compatibility with disperse dyes, and can obtain good dyeing behavior and color fastness. It can be used to evaluate the compound dyeing results in dye house. The δ value of PTT fiber is 10.50, and it can be dyed with traditional disperse dyes. PLA fiber is a kind of aromatic polyester fiber, and its properties are different from PET and PTT fiber. The 8 value of PLA fiber is 12.8, if it is dyed with traditional disperse dyes, PLA fiber can not obtain satisfactory dyeing results, so special disperse dyes for PLA is looked forward to be developed.
