Abstract
A flexible wipe, comprising at least one conformable woven or non-woven layer and at least one adhered nanofiber layer, can be used to remove a variety of particulate soils from planar, curved or complex surfaces that are contaminated by small particulate soil. The nanofiber layer is configured onto the flexible non-woven in a fashion such that particulate of a broad particle size range is trapped or incorporated by the nanofiber layer and efficiently removed from the contaminated surface. The nanofiber layer comprises a web of spun fibers that can incorporate and trap soil particles for efficient soil removal.
