Wipe material with nanofiber layer

Abstract

A flexible wipe comprising at least one conformable 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. The nanofiber layer is configured onto the flexible non-woven in a fashion such that particulate of a broad particle size range is trapped 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.

Description

[0001] The invention is embodied in a surface shape conformable and flexible wipe having at least two layers of material. The wipe comprising a nanofiber layer and a flexible fabric substrate, can remove soils in the form of inorganic or organic particulate, oily or greasy soils, or dispersions of particulate in liquid. The wipe has a layer specifically designed to incorporate finely divided small particle size soil for efficient removal from a variety of contaminated surfaces. The layer can also absorb oily or greasy soils onto the fiber substrate. Further, when used with appropriate liquid (aqueous or organic) cleaning, dusting or other such compositions, the fine fiber layer can obtain an improved surface appearance due to the reduced size of any structure formed from cleaning compositions.

[0002] Both woven and non-woven fabrics have been used for many years for cleaning and polishing purposes. Such fabrics are typically manufactured by forming fiber into a woven or non-woven str...
