Abstract
A meltblown nonwoven fabric is provided having thermoplastic resin fibers having an average fiber diameter of 0.1 to 10 μm, a bulk density of not more than 36 kg/m3 and an air permeability, as measured by a Frazier type method at basis weight of 200 g/m2, of 3 to 100 cc/cm2/sec. The meltblown nonwoven fabric has a low bulk density and is excellent in sound absorption performance, oil adsorption performance, heat insulation performance, dust collection performance and filtration performance. Since the meltblown nonwoven fabric can be formed from one kind of a resin composition, it can be simply and easily produced as compared with the case of using mixed fibers or conjugated fibers formed from many kinds of resins, and the resulting meltblown nonwoven fabric can have uniformity and no variability of properties.
