  • Patent number: 7998384
    Abstract: A spunbond nonwoven fabric useful as a topsheet is produced from polypropylene filaments including a high level of reclaimed polypropylene, while maintaining a product quality, including superior formation, comparable to that obtained when using 100 percent virgin polymer. The spunbond nonwoven fabric is made with multicomponent filaments having at least two different polymer components occupying different areas within the filament cross section, and wherein one of the polymer components comprises reclaimed polypropylene recovered from previously spun polypropylene fiber or webs comprised of previously spun polypropylene fiber. In a specific embodiment, the filaments are sheath-core bicomponent filaments and the reclaimed polypropylene is present in the core component. The core of the bicomponent filament can be comprised of up to 100% reclaimed polypropylene.

  • Patent number: 7276469
    Abstract: The invention is a cleaning material for cleaning printing machines. The cleaning material is comprised of a fabric that has been impregnated with a cleaning composition having branched chain monobasic and/or dibasic esters that contain 2-ethyl hexanoate. The cleaning composition can also include additional low volatility solvents and surfactants. A particularly useful cleaning composition is comprised of isobutyl stearate in combination with branched chain monobasic and/or dibasic esters that contain 2-ethyl hexanoate. The cleaning material can be wound onto a roll that can be adaptable to fit commercially available printing machine cleaning devices.
