“…Meanwhile, the surface composition of the PU–HPAN blended membranes was analyzed by FTIR‐ATR spectroscopy (Figure c). The peaks related to CN and CH 2 bonds on the spectra became gradually stronger which are observed at 2240, 1450 cm −1 , respectively, indicating an increased concentration of the HPAN …”

Directional water transport is a predominant part of functional textiles used for continuous sweat release in daily life. However, it has remained a great challenge to design such textiles which ensure continuous directional water transport and superior prevention of water penetration in the reverse direction. Here, a scalable strategy is reported to create trilayered fibrous membranes with progressive wettability by introducing a transfer layer, which can guide the directional water transport continuously and spontaneously, thus preventing the skin from being rewetted. The resulting trilayered fibrous membranes exhibit a high one-way transport index R (1021%) and a desired breakthrough pressure (16.1 cm H O) in the reverse direction, indicating an ultrahigh directional water transport capacity. Moreover, on the basis of water transport behavior, a plausible mechanism is proposed to provide insight into the integrative and cooperative driving forces at the interfaces of trilayered hydrophobic/transfer/superhydrophilic fibrous membranes. The successful synthesis of such fascinating materials would be valuable for the design of functional textiles with directional water transport properties for personal drying applications.

In this work, an electrospinning technique was developed for the fabrication of poly(vinyl alcohol) (PVA)/soy protein isolate (SPI)/SiO2 hybrid fibres with PVA, SPI and tetraethyl orthosilicate (TEOS) as precursors. The effects of SiO2 content, sodium dodecylsulfate and electrospinning electrical field strength on the morphology and structure of the hybrid fibres were investigated. Scanning electron microscopy (SEM) showed that uniform hybrid fibres about 200 nm in diameter were obtained at a weight ratio of PVA to SPI 8:2, SiO2 content 5.0 wt.%, sodium dodecylsulfate 0.6 wt.% and electrical field strength 0.90 kV cm-1. X-ray diffraction (XRD) patterns showed that the crystalline structure of PVA was somewhat destroyed as PVA was hybridized with SPI and SiO2, and further destroyed under electrospinning process as the stretched molecular chains of the fibre solidified rapidly at high elongation rates, resulting in the amorphism of PVA/SPI/SiO2 hybrid fibres. Fourier-transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) showed that the components of PVA, SPI and SiO2 nanoparticles were linked by hydrogen bonds or Si–O–C bonds in the hybrid fabric networks. Differential scanning calorimetry (DSC) tests showed that the presence of SiO2 nanoparticles considerably improved the thermal stability of the hybrid fibres. Therefore, the PVA/SPI/SiO2 hybrid fibres may have potential as a new fibre in dressings, tissue engineering or drug delivery.
