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.

Sheet material

Process of preparing meltblown fibers that are reclaimed from a starting material of a polypropylene component and a sustainable polymer component is provided. In one aspect, the method includes blending starting fibers of a polypropylene component and a sustainable polymer component under heat to form a molten stream, and then vis-breaking the components to obtain a polymeric blend that is suitable for use in meltblowing applications. The molten stream of the vis-broken polymer components are extruded through a meltblowing die to form a stream of meltblown fibers that is then collected on a collection surface to form a coherent meltblown web. The starting material may be bicomponent filaments having a sheath-core configuration in which the polypropylene component is oriented in the sheath and the sustainable polymer component is oriented in the core of the filaments. The invention is also directed to meltblown fibers and webs prepared from the process.
