Preparation and characterization of tree-like cellulose nanofiber membranes via the electrospinning method.

Cellulose was dissolved rapidly in 9.5 wt.-% NaOH and 4.5 wt.-% thiourea aqueous solution pre-cooled to -5 °C to prepare a transparent solution. Novel cellulose multi-filament fibers were spun successfully, for the first time, from the cellulose dope on an extended laboratory scale. The results from 13 C NMR, scanning electron microscopy and wide angle X-ray diffraction (WAXD) patterns indicated that the fibers exhibited cellulose II character and possessed a circular cross-section and smooth surface. The tensile strength of the novel fibers reached 1.9-2.2 cN·dtex -1 . 2D WAXD and SAXS patterns revealed that, with a drawing progress, the orientation factor increased and mechanical properties were improved.

A Rapid Process for Producing Cellulose Multi-Filament Fibers from a NaOH/Thiourea

Recent years have witnessed the explosive progress of functional materials, which are made by loading various metal oxides onto fabrics. A cost-effective, facile, and simple approach of loading hexagonal zinc oxide (ZnO) sheets onto fabrics is highly desired. Here, the fabrication of the multifunctional ZnO@cotton fabrics is demonstrated using a surface micro-dissolution method by sodium hydroxide/urea (NaOH/urea) and zinc chloride (ZnCl2) aqueous solution. The hexagonal sheet ZnO forms the reflective layer to ultraviolet and near-infrared rays. The UV reflectivity of ZnO@cotton fabric is higher than the raw fabric in the range of 10.9–18.8% and UPF value of treated fabric was 100 + . Infrared barrier results were obtained through the phenomenon of heat radiation transfer obstruction, when fabrics being placed on the hot plate of 120 °C, the temperature difference between raw and treated fabrics is 6.6 °C. Also, the high antibacterial activity against Escherichia coli and Staphylococcus aureus cultures of ZnO@cotton fabric was testified.
