    摘要： The present invention relates to a method for manufacturing a polishing pad. The method of the invention includes the steps of forming a polishing layer from a polyurethane solution has a solid content more than about 90 wt % and drying the polyurethane solution at a temperature from about 130° C. to about 170° C. The invention also provides a polishing pad manufactured by the method mentioned above. The defect of scraping the surface of the substrate to be polished due to polishing particles remaining is avoided when applying the polishing pad according to the invention, and the flatness of the substrate to be polished is raised and the defective rate is eliminated also.

    摘要： The present invention relates to a composite with thermo-formability, a method for making the same and a method for making a casing with a texture on the surface thereof. The composite includes a PU medium layer, a thermo-formable resin layer, a base layer and a surface layer. The thermo-formable resin layer is disposed on the PU medium layer, and includes polyol. The base layer is disposed on the thermo-formable resin layer. The surface layer is disposed on the base layer. As a result, the composite has good stability after thermoforming, and plastic can be injected into the composite, so a PC film is unnecessary. Moreover, the composite may be adhered to a substrate directly or after thermoforming.

    摘要： The present invention relates to a polishing pad and method for making the same. In the invention, a liquid-state polymer material is directly formed on the surface of a base material, and then the liquid-state polymer material is solidified to form a flat grinding layer. Whereby, the polishing pad has high unity and flatness. The grinding layer has attenuated structures and a plurality of holes, thus increasing the storage ability of polishing particles distributed in a polishing liquid. In addition, the polishing pad has high compression ratio, so the polishing pad can compactly contact a polishing workpiece, and will not scratch the surface of the polishing workpiece scratched. Therefore, the polishing effect and quality will be improved.

    摘要： The invention relates to a polishing pad having hollow fibers and a method for making the same. The polishing pad comprises a body and a plurality of hollow fibers. The body has a polishing surface. The hollow fibers are located within the body and have an opening on the polishing surface, wherein the hollow area of the section of each hollow fiber is larger than the sectional area of polishing particles in a polishing slurry. Therefore, the polishing slurry and polishing particles achieve a thorough circulation on the polishing pad via the hollow fibers.

    摘要： The present invention relates to a polishing pad having a surface texture. The surface texture is disposed on the polishing surface of the polishing pad. The surface texture comprises at least one first groove, at least one second groove, and a plurality of holes. The second groove extends from a central portion of the polishing pad to the edge of the polishing pad, and the first groove(s) is intersected with the second groove(s) to form a plurality of intersection points. The holes are disposed at the intersection points, and the depth of the holes is larger than that of the first groove. Thus, the second groove(s) enables impurities suspended in the polishing slurry to be quickly removed from the polishing pad, and the holes can store the polishing slurry to delay the polishing particles in the polishing slurry from departing from the polishing pad.

    摘要： The present invention relates to a sheet for mounting a polishing workpiece. The sheet comprises a substrate, a surface layer and a slightly rough layer. The substrate has a surface. The surface layer is located on the surface of the substrate, with no hole structure existing in the interior thereof, and has a surface. The slightly rough layer is located on the surface of the surface layer to carry and mount the polishing workpiece, with no hole structure existing in the interior thereof. Accordingly, when the polishing workpiece contacts the slightly rough layer, the air therebetween is easily vented out via the slightly rough layer, without the phenomenon of air wrapping, which increases the adsorption force between the polishing workpiece and the sheet.

    摘要： A method is provided for making a polishing pad. In the method, ultrafine fiber-generating fibers are made into a non-woven fabric with two sides. At least one of the sides of the non-woven fabric is made a dense layer. The non-woven fabric is coated with a polymer. Because of the dense layer, the polymer cannot penetrate the non-woven fabric. The ultrafine fiber-generating fibers are converted to ultrafine fibers. Since the dense layer prevents the polymer from penetrating the ultrafine fiber-generating fibers, the ultrafine fibers remain a high concentration of fiber. The ultrafine fibers are transformed into nap. Therefore, the polishing pad is made with a polishing layer that includes the nap. The concentration of fiber of the polishing layer is higher than 80%.

    摘要翻译： 提供了制造抛光垫的方法。 在该方法中，将超细纤维发生纤维制成具有两侧的无纺织物。 无纺布的至少一侧被制成致密层。 无纺织物涂覆聚合物。 由于致密层，聚合物不能穿透无纺织物。 超细纤维生成纤维被转换为超细纤维。 由于致密层防止聚合物渗透超细纤维发生纤维，所以超细纤维保持高浓度的纤维。 超细纤维被转化为绒毛。 因此，抛光垫由包括绒毛的抛光层制成。 抛光层的纤维浓度高于80％。
