Preparation and Characterization of Multilayered Superfine Fibrous Mat with the Function of Directional Water Transport
In the present work,a new kind of multilayer fibrous mats with the specific function of directional water transport is prepared by the combination of melt-electrospinning and solution-electrospinning.The polypropylene (PP) fibrous layer prepared by melt-electrospinning technology is located in the inner layer (next to skin),while the polyacrylonitrile containing hydrophilic nano-silica particles (PAN-SiO2) layer with remarkable hydrophilicity is located in the outer layer,which can effectively transport water to the outer surface of the composites.Treating the as-prepared PAN-SiO2/PP with alkaline aqueous solution of dopamine not only increases the wett(a)bility of the PP layer,but also further improves the hydrophilicity of PAN-SiO2.A layer of cotton woven mesh is added between TPP layer and TPAN-SiO2 to form a sandwich structure in order to accelerate water transport of bilayered fibrous mats.The directional water transport,mechanical property flexibility,and permeability of the prepared multilayered superfine fibrous mat are characterized systematically.Experimental results exhibit that TPAN-SiO2/Cotton mesh/TPP offer excellent accumulative one-way transport index (AOTI,1071%),remarkable overall moisturc management capacity (OMMC,0.88),and reasonably high water vapor transport rate (WVT,11.6 kgd-1m-2),indicating a promising candidate for developing novel textile material used in the fields of sportswear for faster sweat release applications.
