摘要
(JP2014030730W) [Solution] The meltblown nonwoven fabric of the present invention comprises thermoplastic resin fibers having an average fiber diameter of 0.1 to 10 µm, has a bulk density of not more than 36 kg/m 3 and has an air permeability, as measured by a Frazier type method at basis weight of 200 g/m 2 , of 3 to 100 cc/cm 2 /sec. [Effect] The meltblown nonwoven fabric of the present invention 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 of the present invention 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.  The sound absorbingmaterial of the present invention is obtained by a simple process and is excellent in sound absorption performance, so that it can be preferably used as a sound absorbing material of the living environment or transportation means, and weight lightening or thinning of a sound absorbing material can be achieved.
