Nonwoven fabrics having a plurality of fibers that are bonded to each other to form a coherent web, wherein the fibers comprise a blend of a polylactic acid (PLA) and at least one secondary alkane sulfonate are provided. The nonwoven fabrics exhibit increased tensile strengths, elongation and toughness.

Nonwoven fabrics comprising polylactic acid having improved strength and toughness

A method of preparing a cleaning wipe having a high sustainable polymer content is provided. The cleaning wipe includes a fibrous layer having fibers of a melt spinnable sustainable polymer; and an abrasive layer having meltblown fibers of a melt spinnable sustainable polymer. The abrasive layer defining an outer surface of the cleaning wipe, and includes a plurality of abrasive structures formed thereon in which the abrasive structures are formed from conglomerated fibers, meltblown shot, fibers having average diameters greater than 4 micrometers and fibers having a tortuous geometry. The melt spinnable sustainable polymer content of the cleaning wipe is at least 50 weight % by weight of the cleaning wipe. A method of preparing the cleaning wipe is also provided.

Wipes having high sustainable content

Extensible nonwoven fabrics having improved elongation, extensibility, abrasion resistance and toughness. In particular, embodiments of the invention are directed to extensible spunbond fabrics comprising a polymeric blend of a metallocene catalyzed polypropylene, polyethylene, and a third polymer component.

A system and associated method for preparing a composite sheet material is provided. The system includes a nonwoven fabric source; a collection surface onto which a nonwoven fabric is deposited; a carding device disposed downstream of the nonwoven fabric source overlying the collection surface, the carding device including a main cylinder, an air source configured to provide a stream of air; an air manifold having an air inlet in communication with the air source, an air outlet, a fiber inlet, an interior channel, and a fiber outlet. The air outlet is positioned to direct an air stream against a surface the cylinder to dislodge fibers from the surface of the cylinder. The dislodged fibers enter the fiber inlet and flow to the fiber outlet at which point the fibers are deposited onto a surface of the nonwoven fabric. The fabrics are then bonded to form a coherent sheet material.
