Polyester fabrics were dyed with prepared disperse dyes using the high temperature dyeing method. The dye exhaustion of the dye baths were compared to the low-temperature dyeing method in an attempt to study the proportion of the dye effluent solution that affects the environment. The dye uptake of the high temperature dyeing method (HT) of polyester fabric was compared with low temperature dyeing, hence (HT) increased the color strength of the investigated dyes by 309 and 265%. This means that the amount of dye present in the dye effluents by using the high-temperature dyeing method is almost non-existent, and this is reflected positively on the environment as these wastes pollute the environment. Post-treated polyester fabric was prepared through a two-step hot process after being immersed in a solution of Titanium (IV) oxide nanoparticle sizeTiO NPs (21 nm primary particle size) at 80 °C followed by curing at 140 °C. The treated fabric realized an optimum UV protection factor of 34.9 and 283.6 degrees. These fabrics also demonstrated a strong ability to improve the light fastness properties. Finally, the potential applications of such value-added fabrics as self-cleaning and antifungal activities were investigated. The results indicated that the treated dyed fabrics with TiO NPs endowed fabrics with the excellent self-cleaning of methylene blue dye. From the above, the treated fabrics with nano-titanium dioxide can be used in some promising fields, for example, medical ones.
聚酯纤维织物使用高温染色法用制备的分散染料进行染色。将高温染色法和低温染色法的染浴的染料竭染率进行比较，以研究染料废液对环境的影响比例。与低温染色相比，高温染色法（HT）的聚酯纤维上的染料吸光度增加了 309%和 265%，从而提高了所研究染料的色强度。这意味着使用高温染色法时，染液中存在的染料量几乎不存在，这对环境有积极影响，因为这些废物污染环境。经过处理的聚酯纤维织物在 80°C 的 TiO NPs（21nm 初级粒径）溶液中浸泡后，经过两步热加工过程进行后处理，然后在 140°C 下固化。处理后的织物实现了最佳的紫外线防护系数为 34.9 和 283.6 度。这些织物还表现出增强耐光牢度性能的强大能力。最后，研究了此类附加值织物的潜在应用，如自清洁和抗真菌活性。结果表明，经 TiO NPs 处理的染色织物具有优异的亚甲基蓝染料自清洁性能。综上所述，经纳米二氧化钛处理的织物可用于一些有前途的领域，例如医疗领域。
