Sol-Gel Preparation of TiO2/SiO2 Nanocomposites and Their Application in Self- cleaning Textiles

The present study involves the preparation of TiO2/SiO2 nanocrystals and their application in self-clcaning wool-polyester fabrics. The TiO2/SiO2 nanocrystals were successfully synthesized and deposited onto wool-polyester fabrics using the low-temperature sol-gel technique. The as-prepared nanoeomposites and the nanocomposites coated samples were characterized by X-ray diffraction （XRD） and scanning electron microscopy （SEM）, respectively. The XRD and SEM results showed that the single-phase anatase nanocrystallites were formed and loaded on the fabric surface successfully. The photocatalytic activities of TiO2 -coated and TiO2/SiO2-coated wool-polyester fabrics were measured by studying photodegradation of methylene blue dye. Comparison of the photocatalytic activity of the coated samples reveals superiority of TiO2/SiO2 modified sample with respect to that of pure TiO2 modified sample. Our observations indicate that by applying this technique to the fabrics, self-cleaning materials can be designed for practical application.

合成纤维和棉织物表面接触干燥特性的实验研究

采用合成纤维和棉织物作为实验样品，对纤维织物的表面接触干燥过程进行了实验研究，得到了在不同干燥温度下的纤维织物表面温度与干基含水率变化曲线，以及各织物随时间的失重情况对比数据。研究结果表明：在表面接触干燥过程中，织物温度将发生四个阶段的变化，分别为预热升温阶段、水分气化降温阶段、温度回升阶段和恒温阶段。不同种类织物各阶段时间长短有差异，织物中的水分干燥主要发生在降温干燥阶段，纤维织物表面干燥的临界含水率与加热器表面温度有关。
