Abstract:
An abrasive ground fabric which is a composite ground fabric comprising a fiber substrate and a elastic polymer filled in the fiber substrate, wherein(1) the fiber substrate is composed of bundles, each consisting of 20 to 3,000 fine fibers, and (2) the average diameter (D1) of fine fibers existent in a center portion from the center of the cross section perpendicular to a lengthwise direction of each bundle to Â½ of the radius of each fiber bundle is 0.3 to 10 &mgr;m, the average diameter (D2) of fine fibers existent in a peripheral portion from Â½ of the radius to the end of each fiber bundle is 0.05 to 1 &mgr;m, and the D1/D2 ratio is 1.5 or more.
