The present work aims at investigating the effect of applying different dyeing sequences on the imparted functional properties to partially hydrolysed and bleached PET and PET/CO fabrics loaded with TiO₂, ZnO and SnO₂ nanoparticles (NPs). The so obtained dyed fabrics have been characterized using SEM, EDX and FT-IR analytical techniques. The obtained results revealed that, an interaction has taken place between COOH groups created on dyed polyester fabrics and each of the applied NPs. Moreover, the effect of loading and sequence of dyeing wet operation on the functional performances of polyester fabrics was evaluated by estimating its antimicrobial efficacy and ultraviolet protection properties. The antimicrobial activity was tested against B. mycoides, E. coli and C. albicans. It has been found that, loading polyester fabrics with TiO₂ and ZnO during dyeing process using exhaustion or after dyeing using pad-dry-cure methods paves the way for imparting outstanding antimicrobial activity even after five washing cycles. Moreover, the obtained results have also reviled that, the UPF values are dependent on the sequences of the loading of abovementioed NPs during or after dyeing wet operation.

本工作旨在研究对负载有TiO ₂，ZnO和SnO ₂纳米颗粒（NPs）的部分水解和漂白的PET和PET / CO织物施加不同的染色顺序对所赋予的功能特性的影响。如此获得的染色织物已经使用SEM，EDX和FT-IR分析技术进行了表征。所获得的结果表明，在染色的聚酯织物上产生的COOH基团与每个所施加的NP之间已经发生了相互作用。此外，通过估计其抗微生物功效和紫外线防护性能，评估了加湿量和染色湿润顺序对聚酯织物功能性能的影响。测试了抗真菌杆菌，大肠杆菌的抗菌活性和白色念珠菌。已经发现，在用尽的染色过程中或使用轧染-干固化方法染色后，用TiO ₂和ZnO填充聚酯织物，即使在五个洗涤循环后也能赋予优异的抗菌活性。此外，所获得的结果还表明，UPF值取决于在染色湿操作期间或之后的上述NP的负载顺序。
