Poly(lactic acid) melt‐blown (MB) webs were melt‐spun by MB processing of poly(lactic acid) and poly(lactic acid)/filler blends. The effect of tourmaline particles on the structure, morphology, mechanical and filtration properties of poly(lactic acid) blends, and MB webs were reported. The blends and MB webs were characterized using differential scanning calorimetry (DSC), wide‐angle X‐ray diffraction (WXRD), scanning electron microscopy (SEM), and pore size meter (PSM). The degree of crystallinity of blends with tourmaline particles was more than that of poly(lactic acid) alone. SEM micrographs revealed a good dispersion of the additive in the blends and fiber webs. The tourmaline particles offered some benefits to the mechanical properties of the MB web. MB web samples with tourmaline had larger pore size, high surface charge density, and higher filtration efficiency. POLYM. COMPOS., 36:264–271, 2015. © 2014 Society of Plastics Engineers
