Polyester fibers (PES) are the most consumed textile fibers due to their low water absorption; non-ionic character and high crystallinity. However, due to their chemical structure, the chemical interactions between polyester, finishing products, and dyes are quite challenging. We report on the use of ozone to modify the surface of polyester fibers with the goal of improving the interaction of the modified surface with finishing compounds and dyes. We used C.I. Disperse Yellow 211 to dye ozone-treated polyester fabrics and evaluated the effects of ozone treatment using FTIR-ATR, Raman spectroscopy, SEM imaging, rubbing tests, and capillarity measurements. We evaluated the dyeing performance via color analysis, and determined the dyeing kinetics. Experimental results indicate that the modification of polyester fabrics with ozone is a feasible pre-treatment that improves dyeing efficiency allowing better solidity of color and a decrease in the amount of dye required.
聚酯纤维(PES)因其低吸水性、非离子特性和高结晶度而成为消耗量最大的纺织纤维。然而,由于其化学结构,聚酯、整理产品和染料之间的化学相互作用颇具挑战性。我们报道了使用臭氧对聚酯纤维表面进行改性,目的是改善改性表面与整理剂和染料的相互作用。我们使用C.I.分散黄211对经臭氧处理的聚酯织物进行染色,并通过傅里叶变换红外光谱-衰减全反射(FTIR-ATR)、拉曼光谱、扫描电子显微镜(SEM)成像、摩擦测试和毛细作用测量来评估臭氧处理的效果。我们通过颜色分析评估染色性能,并确定染色动力学。实验结果表明,用臭氧对聚酯织物进行改性是一种可行的预处理方法,可提高染色效率,使颜色更牢固,并减少所需染料量。
