20120156416 | PILLING-RESISTANT ARTIFICIAL LEATHER - An artificial leather is provided having a raised nap to give an elegant appearance, and further has a good pilling-resistance without affecting the spinning performance. The pilling-resistant artificial leather is a sheet-form object including a microfiber having a monofilament diameter of 0.3 to 10 μm and a polymeric elastomer, and having a raised nap made of the microfiber. The microfiber includes inorganic particles in a proportion of 0.01 to 5% by mass relative to 100% by mass of the microfiber, and a silicone oil in a proportion of 0.001 to 1% by mass relative to 100% by mass of the microfiber. The microfiber contains a polyester microfiber in a proportion of 90% by mass or more thereof. | 06-21-2012 |
20130157551 | POLISHING CLOTH AND METHOD FOR PRODUCING SAME - A high performance polishing cloth having a densified surface state with ultrafine fiber bundles uniformly dispersed therein and having excellent smoothness is provided. The polishing cloth comprises a nonwoven fabric formed by entangling the ultrafine fiber bundles formed by bundling ultrafine fibers with an average single fiber diameter of 0.05 to 2.0 μm and a polymeric elastic material, wherein the average size of the surface fiber-napped portions constituted by the aforementioned ultrafine fiber bundles of the aforementioned nonwoven fabric in the width direction of the ultrafine fiber bundles is 50 to 180 μM. | 06-20-2013 |
20130331014 | POLISHING PAD - A polishing pad is provided with a compression elastic modulus of 0.17 MPa or more and 0.32 MPa or less produced by preparing a nonwoven fabric formed of bundles of ultrafine fibers with an average monofilament diameter of 3.0 μm or more and 8.0 μm or less, preparing a polishing pad base by impregnating the nonwoven fabric with a polyurethane based elastomer in an amount of 20 mass % or more and 50 mass % or less relative to the mass of the polishing pad base, and laminating the polishing pad base with a porous polyurethane layer containing wet-solidified polyurethane as primary component which has openings with an average opening diameter of 10 μm or more and 90 μm or less in its surface to serve as polishing surface layer. | 12-12-2013 |
