Abstract
The present invention provides a flexible, coated abrasive product having a fabric or cloth substrate. The fabric has a warp direction and a fill direction and is preferably woven. The finished coated abrasive product is manually tearable in the warp direction in a straight line. The product is characterized by having a tear strength across the warp direction that is at least twice the tear strength across the fill direction. Tearing of the present products takes place along, or contiguous to, a single yarn in the warp direction. The coated abrasive product of the invention is particularly useful in the form of belts, elongated sheets or rolls.
