用制备的分散染料对涤纶织物进行高温染色。通过对染料浴法和低温染色法的染料耗用情况进行比较，试图研究出染液比例对环境的影响。对高温染色法对涤纶织物的染率与低温染色法进行了比较，结果表明高温染色法可使所研究染料的色强分别提高309和265%。这意味着使用高温染色方法的染料废水中存在的染料量几乎为零，这对环境有积极的影响，因为这些废物污染了环境。涤纶织物经两步热处理后，在初始粒径为21 nm的氧化钛纳米颗粒粒径为tio2 (2) NPs的溶液中浸泡80℃，然后在140℃固化，织物的最佳防紫外线系数分别为34.9和283.6度。这些织物也表现出较强的改善耐光性的能力。最后，对这些增值织物在自清洁和抗真菌活性方面的潜在应用进行了探讨。结果表明，经TiO2纳米粒子处理后的染色织物具有优异的亚甲基蓝自清洁性能。综上所述，纳米二氧化钛处理后的织物可用于一些有前景的领域，如医疗领域。
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(2) NPs (21 nm primary particle size) at 80 degrees C followed by curing at 140 degrees 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 TiO2 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.
