Abstract: PROBLEM TO BE SOLVED: To provide a cloth for polishing a magnetic disk allowing texture machining of uniform surface roughness Ra regardless of size of grains. SOLUTION: At least weft comprises crimped threads mainly made of polyester extra fine filament fiber with substantially round cross section, and the weft covers larger area of a surface than warp. The cloth comprises five or more satin fabric with cover factor CF represented by the following equation is 2400-3400. CF=[warp total fineness (dtex)]1/2 × warp density (number/25.4 mm) + [weft total fineness (dtex)]1/2 × weft density (number/25.4 mm).

Abstract: PROBLEM TO BE SOLVED: To provide a cloth for polishing a magnetic disk allowing texture machining of uniform surface roughness Ra without cutting of thread, when slurry containing free grains with 1 μm or less of average grain size is used. SOLUTION: In the cloth for polishing the magnetic disk using the slurry containing free grains with 1 μm or less of average grain size crimped thread of polyester extra fine filament fiber with single fiber diameter D of 0.01-10 μm and D/d>=27 for average grain size d of the grains is used as weft. The cloth comprises five or more satin fabric with cover factore CF of 2400-3400 represented by the following equation. CF=[warp total fineness (dtex)]1/2 ×warp density (number/25.4 mm) + [weft total fineness (dtex)]1/2 × weft density (number/25.4 mm).

Abstract: PROBLEM TO BE SOLVED: To provide a woven fabric for dustproof garment and the resultant dustproof garment having both high antistatic performance and dust-trapping efficiency having been unable to be attained by conventional technology and also having high laundering durability. SOLUTION: The woven fabric comprises (A) combined filament yarns which, in turn, comprise electrically conductive conjugate filaments made from a fiber- forming polymer and an electrically conductive microparticles-containing polymer with a part of the latter polymer exposed on the fiber surface and an electrically conductive microparticles-free filaments and (B) electrically conductive microparticles-free filaments, wherein the combined filament yarns A are used as both the warps and wefts at 2-10 mm intervals, and an antistatic agent adheres to the fiber surface. The woven fabric has a dust-trapping efficiency of ≥50% and a frictional electrification voltage of ≤100 V. COPYRIGHT: (C)2003,JPO
