Abstract: The present invention relates to a sheet for mounting a polishing workpiece. The sheet comprises a substrate and a surface 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 plurality of through holes. Accordingly, when the polishing workpiece contacts the surface layer, the air therebetween is vented to the substrate via the through holes and then is easily vented out, without the phenomenon of air wrapping, which increases the adsorption force between the polishing workpiece and the sheet, thereby improving the polishing effect of the polishing workpiece.

Abstract: 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%.

First, ultramicrofiber-forming fibers having an islands-in-sea type cross-sectional configuration are formed by blend spinning or conjugate spinning. Secondly, a porous reinforcement sheet of low compactness is formed from polyester, polyurethane or polyolefin by spunbonding, meltblowing or calendering.

The nonwoven is impregnated or coated with an elastomer resin composition, and then subjected to a coagulating process, a washing process, a drying process and a removing process to produce a semi-product leather. Finally, the semi-product leather is then processed to produce the artificial leather.

Abstract: There is disclosed a method for making environment-friendly artificial leather from ultra micro fiber without solvent treatment. The method includes the step of making at least two components into ultra micro fibers, as raw materials, by means of conjugate spinning.

Non-woven cloth is made of the fibers. The non-woven cloth is soaked in water at 50 to 90° C. Thus, the fibers curl so that the non-woven cloth is elastic.

Alternatively, the non-woven cloth includes, in addition to the fibers (“first type of fibers”), additional fibers (“second type of fibers”) that can be dissolved in water, alkali or solvent. The non-woven cloth is soaked in PU resin, washed and dried. The second type of fibers is removed from the non-woven cloth and the PU resin in order to leave elongated spaces. Thus, the artificial leather is elastic.
