<P>PROBLEM TO BE SOLVED: To provide an abrasive cloth for texture machining, achieving base surface roughness of 0.3 nm or less, being immune to scratch defect and ridge defect and forming a texture mark with high linear density. <P>SOLUTION: This abrasive cloth is formed of a sheet-like material composed of non-woven fabric made of very fine fiber bundle having an average single fiber fineness of 0.00001 to 0.1 dtex and an elastic polymer. The water absorption speed measured by JIS L-1907 Bayh Lec method (2004 version) ranges from 1 to 50 mm. <P>COPYRIGHT: (C)2008,JPO&INPIT |
