Large denier nonwoven fiber webs
Various embodiments disclosed relate to an abrasive article. The abrasive article includes a nonwoven web. The non-woven web includes a first irregular major surface and an opposite second irregular major surface. The nonwoven web further includes a fiber component comprising staple fibers having a linear density ranging from about 50 denier to about 2000 denier and a crimp index value ranging from about 15% to about 60%. The nonwoven web further includes a binder dispensed on the fiber component and abrasive particles dispersed throughout the nonwoven web.
INTAKE FILTER FOR VEHICLE AND MANUFACTURING METHOD THEREOF
A shaped cross-section composite fiber for an intake filter is manufactured from a single material of polypropylene, without separate binder processing by using the single material of polypropylene as a filter material. The shaped cross-section composite fiber includes: a sheath comprising a reformed polypropylene resin; and a core comprising a polypropylene resin, where the sheath and the core are combined to provide a sheath-core structure.

METHOD FOR PRODUCING A COMPOSITE NONWOVEN FABRIC AND DEVICE FOR PRODUCING A COMPOSITE NONWOVEN FABRIC
A method for producing a composite nonwoven fabric having at least two layers, wherein a first layer is made of long fibers, and a second layer is made of short fibers. The method includes attaching, in a production line, the short fibers of the second layer to the long fibers of the first layer in a wet laid process via a headbox. The headbox has a round flow or cross flow distributor with a rotating or static turbulence generator.

ELASTOMERIC LAMINATE WITH SOFT NONCRIMPED SPUNBOND FIBER WEBS
An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions. The article also includes a chassis having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and an ear joined to the chassis. The ear includes a laminate formed from a nonwoven and an elastomeric material sandwiched between said first and second nonwovens. The laminate further includes a plurality of ultrasonic bonds.
Biopolymer-containing nonwoven fabric
Nonwoven fabrics including a first spunmelt through-air-bonded (TAB) nonwoven layer comprising a first plurality of spunmelt fibers, in which the first plurality of spunmelt fibers comprise a biopolymer. The first plurality of spunmelt fibers may be physically entangled with cellulosic fibers, such by hydroentangling. Methods of forming a nonwoven fabric including a first spunmelt TAB nonwoven layer are also provided.
