Abrasive cloth and process for production thereof

The invention provides an abrasive cloth, on the surface, ultrafine-denier fibers which have a number-mean single-fiber fineness of 1*10 to 1.4*10 dtex and a content of fibers whose single-fiber finenesses fall within the range of 1*10to 1.4*10 dtex of 60% or above, characterized in that on average...

Zusammenfassung:	The invention provides an abrasive cloth, on the surface, ultrafine-denier fibers which have a number-mean single-fiber fineness of 110 to 1.410 dtex and a content of fibers whose single-fiber finenesses fall within the range of 110to 1.410 dtex of 60% or above, characterized in that on average 500 or more intersections showing on the surface between ultrafine-denier fibers whose single-fiber finenesses fall within the range of 110 to 1.410 dtex are present as determined by observing fifty 0.01mm areas under a scanning electron microscope (SEM) at a magnification of 2,000.
