Abstract
Cleaning articles comprising a nonwoven web or foam, binder, and organic particles. In another aspect, the present invention provides a method for cleaning soiled surfaces utilizing cleaning articles comprising a nonwoven web or foam, binder, and optionally organic particles
Claims47
A cleaning article comprising:
- a non-woven, three dimensional fibrous web comprised of at least one intertangled organic fiber, the web having a first major surface;
- a plurality of organic particles having a Shore A hardness less than 80;
- and
- binder on at least a portion of the first major surface, the binder having a Tg not greater than +10° C. and binding the organic particles, at least in part, to the first major surface.

A cleaning article comprising:
- a non-woven, three dimensional fibrous web comprised of at least one intertangled organic fiber, the web having a first major surface;
- a plurality of organic particles having a hardness of at least one of a Shore A hardness in the range from 80 to 100 or a Shore D hardness in the range from 30 to 50;
- and
- binder on at least a portion of the first major surface, the binder having a Tg not greater than 0° C. and binding the organic particles, at least in part, to the first major surface.

A method of cleaning a soiled exterior surface of an aircraft, the method comprising:
- providing a cleaning article comprising a non-woven, three-dimensional fibrous web, at least 8 mm thick, comprised of at least one intertangled organic fiber, the web having a first major surface and binder on at least a portion of the first major surface, the binder having a Tg not greater than 0° C., said cleaning article further comprising a work surface comprising said binder, and said work surface having a wet kinetic coefficient of friction in the range from 0.3 to 0.9;
- frictionally engaging at least a portion of the work surface of the cleaning article with the soiled exterior surface of the aircraft;
- and
- inducing relative motion between the cleaning article and the soiled exterior surface to at least partially dislodge soil from the soiled exterior surface.
