In order to have a better understanding of mechanical properties of the Nano-TiO2 antibacterial cotton fabric, FAST system was used to measure the compression, bending, shearing, extension and other low stress mechanical properties of cotton fabrics with and without treated by Nano-TiO2 antibacterial. The structural parameter and dimensional stability are also tested. Results indicated that weight, weft density, surface thickness, bending, formability, shearing and relaxation shrinkage of weft direction are all increased slightly, while shearing at warp 45°, relaxation shrinkage of warp direction and hygral expansion decreased. As a whole, most of the mechanical properties are still within the normal range and some is even better.

The article explored the finishing process of cotton fabric with nano titanium dioxide and adopted the dipping-rolling-drying process for the purpose of cotton fabric with good ultraviolet (UV) resistant performance. In this study, the concentration of titanium dioxide acted as variable factor to test and analysis the regular pattern of fabric UV resistant performance, mechanical properties and wearability after being treated with different concentrations of titanium dioxide solution. The results showed that the property of UV resistance improved with the increase of solution concentration. The ultraviolet protection factors (UPF) of fabric was 43.5 at a concentration of 0.5%, which was beyond the UV resistant standard of 40. However, the mechanical properties and wearability decreased in varying degrees with the increase in concentration of titanium dioxide. Thus the overall performance should be considered comprehensively to select the finishing process. All of these conclusions provide basic data for some in-depth research in the future.

The effect of enzyme treatments with consecutive softening by the use of silicone – polyurethane on low stress mechanical properties and hand values of jute/cotton union fabric have been studied on the Kawabata evaluation system (KES). The results indicate that the enzyme treated, silicone – polyurethane finished fabric has significant (p<0.05) improvement in tensile resilience, fabric extensibility, compressional resistance and friction co efficient, whereas fabric thickness, linearity of tensile, surface roughness, bending and shear rigidity and their hysteresis are reduced compared to the untreated fabric. Under the Kawabata system, the Koshi (stiffness) value of the finished fabric is decreased by 1-9%. Numeri (smoothness) and Fukurami (fullness and softness) values are increased by 11-20% and 3-4% respectively compared to the untreated fabric. The variation in primary hand values are significant (p<0.05). The total hand value (THV) is also increased by 6% and 44% for the case of 40/60 and 50/50 jute/cotton union fabrics, respectively. This study confirms the possible usage of jute/cotton fabric in the apparel segment.

Poly(arylene ether sulfone) (PES)–titanium dioxide (TiO2) hybrid membranes were prepared via solution blending method using TiO2 nanoparticles as inorganic filler. The chemical structure and thermal stability of the matrix polymer were characterized by proton nuclear magnetic resonance, Fourier transform infrared, differential scanning calorimetry, and thermogravimetric analysis. The crystal structure, morphology, mechanical properties, and gas separation performance of hybrid membranes were characterized in detail. As shown in scanning electron microscopic images, TiO2 nanoparticles dispersed homogeneously in the matrix. Although the mechanical properties of hybrid membranes decreased certainly compared to the pure PES membranes, they are strong enough for gas separation in this study. All gas permeability coefficients of PES-TiO2 hybrid membranes were higher than pure PES membranes, attributed to the nanogap caused by TiO2 nanoparticles, for instance, oxygen and nitrogen permeability coefficients of Hybrid-3 (consists of PES with 4-amino-phenyl pendant group and hexafluoroisopropyl (Am-PES)-20 and TiO2 nanoparticles, 5 wt%) increased from 2.57 and 0.33 to 5.88 and 0.63, respectively. In addition, the separation factor increased at the same time attributed to the stimulative transfer effect caused by the interaction of hydroxyl groups on the TiO2 nanoparticle and polar carbon dioxide molecules.
