Fig. 6From: Colorful Hydrophobic Poly(Vinyl Butyral)/Cationic Dye Fibrous Membranes via a Colored Solution Electrospinning ProcessThe effects of dye concentration on the color strength (\( \overline{K/S} \) the left y-axis) and the level-dyeing property (σK/S, the right y-axis) by taking PVB/X-10GFF as an example. The top images of color deepened NFMs corresponding to the e-spun PVB/X-10GFF NFMs with increasing dye concentrationBack to article page
