Polishing cloth |
| abstract |
An object of the present invention is to suppress the occurrence of scratches (scratch) on the surface of a substrate when texturing an aluminum alloy substrate, which is excellent in the uniformity of the fiber diameter of the ultrafine fibers present on the surface of the substrate and the uniformity of the surface fiber density. In addition, the present invention provides a polishing cloth which can be finished as a highly-accurate processed surface capable of coping with a high recording density of a recording disk, in which the productivity is remarkably improved and the substrate surface roughness after polishing is extremely small. thing. A nonwoven fabric formed by entanglement of polyamide ultra-short fibers having an average fiber diameter of 0.5 to 4 μm and a fiber diameter CV value of 10% or less has an integral structure with a polymer elastic body, and at least one surface has It is composed of a sheet having a raised surface, and the linear density of the number of surface fibers on the raised surface is 30 fibers / 100 μm width or more, and the CV value of the linear density in the continuous longitudinal direction of the sheet is 10% or less. A polishing cloth characterized by the following. [Selection diagram] Fig. 1 |
