Abstract: The sound absorbing material 50 comprises: a felt-like fiber body 51 which includes 15 to 70% by weight of fine fibers with a fineness of 1 denier or less, 20 to 60% by weight of hollow fibers having inner cavities, and 10 to 40% by weight of binder fibers that join the fibers together; and a nonwoven fabric 52 that is laminated on a surface of the felt-like fiber body 51. The nonwoven fabric 52 includes a plurality of drawn long fibers arranged and oriented in one direction. An average diameter of the plurality of long fibers is in the range of 1 to 4 μm. The sound absorbing material 50 has a thickness in the range of 8 to 45 mm and a bulk density of 20 kg/m3 or less.

Abstract: A transparent net structure including two or more uniaxial alignment bodies of a multilayer film which includes a thermoplastic resin layer containing at least one polypropylene (T) selected from the group consisting of block polypropylene and random polypropylene polymerized with a metallocene catalyst, and an adhesive layer containing polypropylene (A) polymerized with a metallocene catalyst and laminated on at least one surface of the thermoplastic resin layer, in which the two or more uniaxial alignment bodies are laminated or woven such that the adhesive layers are interposed among the two or more uniaxial alignment bodies and alignment axes of the two or more uniaxial alignment bodies intersect with each other.
