ABSTRACT:
A process for making cloth backing for coated abrasive articles is disclosed wherein a backing material is coated on its front side, with a liquid thermosetting resin, in such a manner that the resin does not permeate the interstices of the cloth. As a result, the cloth retains most of its original pliability when incorporated in the finished coated abrasive article. A back sizing, of for example glue, may also be applied in the same manner to provide a coated abrasive backing material which is both front sized and back sized but which still possesses most of its original pliability.
