The present invention provides a mounting mat for mounting a pollution control element or monolith in a pollution control device, said mounting mat comprising a layer having a mixture of long and short fibers wherein said short fibers have a length of not more than about 13 mm and wherein said long fibers have a length of at least about 20 mm and wherein the amount of said short fibers is at least about 3% by weight based on the total weight of said mixture of long and short fibers.

A nonwoven fabric web having an excellent sound absorption coefficient in a frequency range from 800 Hz to 1000 Hz when used as a sound absorbing member for a vehicle exterior. The nonwoven fabric web including a nonwoven fabric having meltblown fibers and binder fibers arranged so as to be confounded with the meltblown fibers and fused with the meltblown fibers at some of the confounding points at the very least, the weight per unit area of the nonwoven fabric being from 400 g/m.sup.2 to 1500 g/m.sup.2, and the flexural rigidity of the nonwoven fabric being from 2.0 N/50 mm to 20.0 N/50 mm.

Disclosed is a vehicular engine room manufacturing method wherein the engine room has excellent heat resistance and sound-absorbing characteristics, and scraps generated during the manufacturing process can be recycled. The vehicular engine room manufacturing method comprises the steps of: carding a thermoplastic fiber and a carbon fiber having a length of 10 to 150 mm and needle-punching the same, thereby forming a felt layer; applying heat and pressure to the felt layer, thereby forming a felt board; and applying heat to the felt board and shaping the same is formed in a desired shape.

A smokeless tobacco product includes smokeless tobacco and structural fibers. The structural fibers forming a network in which the smokeless tobacco is entangled. The structural fibers have a composition different from the smokeless tobacco. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers.

A device for producing a composite nonwoven web which includes a first layer and a second layer. The first layer has a spunbonded nonwoven and/or long fibers. The first layer has an upper face and a first width. The second layer has short fibers and a second width. The device includes at least one conveyor device which transports at least the first layer in a conveying direction, a headbox system which dispenses the short fibers onto the upper face of the first layer between two edges which extend transversely to the conveying direction, and a collecting device which is arranged so that some of the short fibers dispensed from the headbox system can be collected in a region of at least one of the two edges before the short fibers which are dispensed in the region come into contact with the upper face of the first layer.

Methods and systems are provided for a process to generate a nonwoven textile. In one example, the nonwoven textile may have layered, zonal properties resulting from entangling of two or more types of staple fibers through a merging region between the layers of staple fibers while maintaining distinct zones, each zone comprising a type of staple fiber. Furthermore, the process may include embedding a filament layer into the nonwoven textile via a continuous assembly line.
