ABSTRACT:
An improved fabric for covering dampener rolls comprising a ground yarn utilizing a water shrinkable yarn and a hydrophilic yarn knitted together in the same course of the fabric. The fabric is fashioned into a cylindrical tube and is securely fastened to a roll by thoroughly wetting the tubular fabric and roll in water until the water shrinkable yarn shrinks causing the fabric to tighten down on the roll. When the water shrinkable portion of the ground yarn in the dampener cover shrinks, it does so in a widthwise or circumferential manner, thereby exerting a force upon the surface of the dampener roll, thus securing the dampener cover to the dampener roll. This unique fabric construction permits the hydrophilic yarn to be drawn close together as the water shrinkable yarn shrinks, permitting the fabric to have a substantially smooth surface, thus eliminating patterning of a product made thereby.
