“Nano titanium dioxide (TiO2) sols were prepared by sol-gel method with tetrabutyl orthotitanate (TBOT) as precursors, citric acid (CA) as inhibitors. Ultraviolet resistant capacity

of finished cotton fabrics are greatly improved with good wrinkle-resistance, whiteness and tensile strength as well. The optimum molar ratio for preparing nano-TiO2 sols in this study is n[C2H5OH] : n[H2O] : n[CA] : n[HCl] : n[TOBT] = 20 : 6 : 1.2 : 0.025 : 1, at ambient temperature. Particle size distribution analysis of the sol reveals that the curve is right tailed with an average diameter of 72.8 nm.

The optimum finishing results can be obtained with 3% SHP, 3% TEA, curing at 165 degrees C for 3 min. Aggregated nano-TiO2 particles on surfaces of finished cotton fibers both

washed and unwashed were investigated by high resolution cold field emission scanning AZD1208 electron microscope and energy dispersive X-ray spectrometer. Esterification crosslinking between CA and cotton fibers were also demonstrated through infrared spectra. After a five-time’s wash, ultraviolet protection factor of finished cotton fabrics with nano-TiO2 sols is up to 117.42 and dry crease recovery angles increase by 30.2 degrees with slightly improved whiteness, while the breaking strength decreases by 18.8%.

“Encapsulated

microspheres have been widely used in various biomedical applications. However, fabrication of encapsulated microspheres from highly viscous materials has always been a manufacturing challenge. The objective of this study is to explore a novel metallic foil-assisted laser-induced forward transfer (LIFT), a laser-assisted fabrication technique, to make encapsulated microspheres using high sodium alginate concentration solutions. The proposed four-layer approach selleck screening library includes a quartz disk, a sacrificial and adhesive layer, a metallic foil, and a transferred suspension layer. It is found that the proposed four-layer modified LIFT approach provides a promising fabrication technology for making of bead-encapsulated microspheres from highly viscous solutions. During the process, the microsphere only can be formed if the direct-writing height is larger than the critical direct-writing height; otherwise, tail structured droplets are formed; and the encapsulated microsphere diameter linearly increases with the laser fluence and decreases with the sodium alginate concentration.
