VEHICULAR ENGINE ROOM MANUFACTURING METHOD
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.
Bicomponent Polymeric Fibers
A bicomponent fiber comprising a sheath, where the sheath includes a propylene-based elastomer, said propylene-based elastomer including propylene-derived units and from about 3.0 to about 15 wt % alpha-olefin-derived units other than propylene-derived units, based upon the entire weight of the copolymer, said propylene-based elastomer having a triad tacticity of greater than 75%, and a heat of fusion, as determined by DSC, of less than 75 J/g; and a core, where the melt temperature of the core, as determined by DSC, is at least 5% greater than the melt temperature of the sheath.

Method for making a shaped nonwoven
A method for making nonwoven fabric. The nonwoven fabric can include three-dimensional features that define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property. The nonwoven further has a plurality of apertures, wherein at least a portion of the aperture abuts at least one of the first region and the second region of the microzone.
FILAMENT REINFORCED TAPES USEFUL AS UNDERWATER PIPE WRAP
A member for use in undersea applications comprising a plurality of conduits assembled into a bundle; the bundle being wrapped with a pressure-sensitive tape comprising a backing, a layer of corrosion-resistant filaments on one surface of the backing, and pressure-sensitive adhesive layer that coats the filaments and binds them to the backing.
FABRIC HAVING TOBACCO ENTANGLED WITH STRUCTURAL FIBERS
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.
