A polyolefin material that comprises a thermoplastic composition that is annealed and thereafter drawn in a solid state is provided. The composition contains a continuous phase that includes a polyolefin matrix polymer and a nanoinclusion additive dispersed within the continuous phase in the form of discrete domains. A porous network is defined within the thermoplastic composition that includes a plurality of nanopores, wherein the thermoplastic composition has a glass transition temperature of from about −20° C. to about 50° C. as determined in accordance with ASTM E1640-13.

A fibrous nonwoven structure formed of a blend of cellulose pulp fibers and melt spun polymer filaments is disclosed. The structure may include a distribution of a plurality of macroscopically visible shaped particles of substantially similar size and shape, included in the blend. The structure may also include outer scrim layers formed of melt spun polymer filaments. A method of manufacturing the fibrous nonwoven structure is also disclosed.

A non-woven fabric, non-woven fabric producing method and an acoustic absorbent of desirable properties are provided. The non-woven fabric is a non-woven fabric including a plurality of ultrafine fibers configured from a thermoplastic resin, and comprises: a base portion configured by entangling of some of the plurality of ultrafine fibers; and a fiber bundle configured by entangling and bundling of other ultrafine fibers in the plurality of ultrafine fibers, and that is entangled with the base portion. The fiber bundle has a lower void fraction than a void fraction of the base portion.
