摘要:
The present invention relates to a polishing pad comprising a polishing surface. The polishing surface comprises a first polishing area and a second polishing area. The first polishing area comprises a plurality of first foaming holes, and the second polishing area comprises a plurality of second foaming holes, and an average pore diameter of the first foaming holes is less than an average pore diameter of the second foaming holes. The polishing pad according to the present invention uses the polishing areas with the different pore diameters of the holes to avoid unevenly removing the edge and central part of a substrate when polishing, so that a thickness of the substrate becomes uniform.

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.

The present invention relates to a thermoplastic polyurethane fiber and a method for producing the same. A thermoplastic polyurethane material is firstly provided and subjected to a molten extruding process to form a fiber material. Next, an extension process is performed to the fiber material to obtain the thermoplastic polyurethane fiber of the present invention. The thermoplastic polyurethane fiber has a lower thermal shrinking property, thereby meeting requirements of the application.
摘要:
A thermoplastic artificial leather is provided, which includes a first structure layer, a second structure layer, a plurality of recycled particles, and a third structure layer, in which the second structure layer is disposed on the first structure layer, the plurality of recycled particles disposed on the second structure layer, and the third structure layer is disposed to cover the plurality of recycled particles. According to above stacked structure, the thermoplastic artificial leather with environment friendly is formed, and the plurality of recycled particles is processed in a physical manner, which can solve the problem, the environmental protection issue, caused by the use of solvent to process the recycled particle in the prior art. Use of the material characteristics of each structure layer to reprocess the recycled particles, so the reprocess procedure without using any solvent, so the environmental pollution and the production cost are greatly reduced.
