This invention relates to articles for cleaning, buffing, conditioning, or restoring surfaces. Abrasive articles made from nonwoven fibers have long been used for cleaning floors and other surfaces. Although previously known nonwoven abrasive articles are extremely useful for the purposes for which they are intended, they rapidly lose their efficiency as they become saturated with dirt. This invention provides an abrasive article comprising an open, lofty nonwoven web comprising helically crimped synthetic organic fibers. The article can optionally contain stuffer box crimped fibers and melt bondable fibers. The presence of helically crimped fibers brings about greater durability and greater capacity for absorbing debris. |
