The main purpose of this study was to evaluate the ultraviolet protective factor (UPF) of fabrics coated with TiO2 nanoparticles made using an synthesis method and more accurately assess the intrinsic properties of the textile. The cotton-polyester twill fabric (70-30%) (246.67 g/m2) was coated with TiO2 nanoparticles. coating is conducted in 4 steps; washing the fabrics, preparation of nanoparticles, injecting the nanoparticles into fabrics, and drying the fabric after coating. The scanning electron microscope (SEM) and X-ray diffraction (XRD), FTIR spectrometer, dynamic light scattering (DLS) and UV-Vis spectrophotometer were used to analyse the data of the coating and UPF results. Also, four standards such as ASTM D737, ISIRI 8332, ISIRI 4199, and ISIRI 567 were used for analyzing the intrinsic properties of a textile. The results of SEM, XRD and DLS altogether confirmed the formation of nanoparticles onto textile fibers. Moreover, the UPF value of the uncoated and coated fabrics was 3.67 and 55.82, respectively. It was shown that the deposition of TiO2 nanoparticles on fabric can provide adequate protection against UVR. Also, the results of analyzing the intrinsic properties of the textile showed that there were no significant differences in the intrinsic properties between the coated and uncoated fabrics. Based on the results, it can be concluded that the UV protective properties of workwear fabrics can be improved by coating TiO2 nanoparticles on them without any effect on the cooling effect of perspiration evaporation.
本研究的主要目的是评估使用 合成方法制备的 TiO2 纳米颗粒涂层织物的紫外线防护因子（UPF），更准确地评估纺织品的固有特性。棉涤斜纹织物（70-30%）（246.67 g/m2）被涂覆 TiO2 纳米颗粒。涂层通过 4 个步骤进行；洗涤织物、制备纳米颗粒、将纳米颗粒注入织物以及涂层后干燥织物。扫描电子显微镜（SEM）和 X 射线衍射（XRD）、傅里叶变换红外光谱仪（FTIR）、动态光散射（DLS）和紫外可见分光光度计用于分析涂层和 UPF 结果的数据。此外，还使用了四个标准，如 ASTM D737、ISIRI 8332、ISIRI 4199 和 ISIRI 567，来分析纺织品的固有特性。SEM、XRD 和 DLS 的结果共同证实了纳米颗粒在纤维上的形成。此外，未涂层和涂层织物的 UPF 值分别为 3.67 和 55.82。结果表明，TiO2 纳米颗粒在织物上的沉积可以为 UVR 提供足够的保护。此外，对纺织品固有特性的分析结果表明，涂层和未涂层织物的固有特性之间没有显著差异。基于这些结果，可以得出结论，通过在工作服织物上涂覆 TiO2 纳米颗粒可以提高其紫外线防护性能，而不会对汗液蒸发的冷却效果产生任何影响。
