Abstract
The present invention is directed to an abrasive substrate formed by the application of a polymer composition to the surface of the substrate. The polymer composition is applied to the substrate in a manner producing an uneven, structured coating on the substrate, resulting in a surface having abrasive properties. The invention is especially useful in producing abrasive non-woven materials useful as wet and dry wipes.
Claims14
An abrasive substrate comprising a substrate having directly deposited on at least one surface, in a non-homogeneous manner, a cured polymer composition, wherein said polymer composition has an MFFT of greater than −10° C. and said polymer composition comprises one or more polymers having a Tg or greater than 0° C., wherein the cured polymer composition on the substrate surface is abrasive, and wherein said abrasive substrate is free of abrasive particles.
The abrasive substrate wherein less than 20 percent by weight of the polymer coating penetrates more than 20 percent into the substrate.
