Description of the Invention: The present invention relates to a polishing pad and a method of manufacturing the same, and more particularly to a polishing pad having abrasive particles and a method of manufacturing the same. [Prior Art] A conventional polishing method employs a polishing liquid in combination with a polishing enamel mode. The polishing slurry has a plurality of abrasive particles for polishing the surface of a polished workpiece. The polishing crucible has a plurality of holes which are interconnected to cause the polishing liquid to be evenly distributed on the surface of the polishing pad to enhance the polishing ability. The disadvantages of this conventional polishing method are as follows. When the polishing liquid flows through the holes during polishing, the abrasive grains of the polishing liquid tend to block the holes, resulting in a decrease in polishing ability. Then, the holes that are blocked are trimmed with a dresser to restore the polishing ability of the polishing pad. However, adding this procedure to the original process will increase costs and reduce efficiency. Another conventional polishing method uses a polishing pad having abrasive particles. Referring to Fig. 1, there is shown a schematic view of a polishing pad having abrasive grains disclosed in the Republic of China Patent Publication No. 1233384. The polishing pad 1 having abrasive particles includes a bottom layer 11 and a polishing layer 12. The polishing layer 12 is disposed on the bottom layer 11. The polishing layer 12 has a resin 121 and a plurality of abrasive grains 122. The resin 121 covers the abrasive particles 122 having a polished surface 1211. A portion of the abrasive particles 122 are exposed to the polishing surface 1211 of the resin 121. The disadvantages of the conventional polishing pad 1 having abrasive grains are as follows. The polishing pad 1 having the abrasive 130536.doc -6-201016391 particles is used to fix the abrasive particles 122 by the resin 121, so that the polishing particles 122 are fixed at the same position during polishing, and are ground in the same direction with the same stress. It is easy to cause scratches on the workpiece to be polished. At the same time, the resin 121 is gradually removed, and the area of the abrasive grains 122 fixed in the resin 121 exposed to the polishing surface 12 11 is increased, resulting in a more serious scratch. Therefore, it is necessary to provide an innovative and progressive polishing pad having abrasive grains and a method of manufacturing the same to solve the above problems. SUMMARY OF THE INVENTION The present invention provides a polishing crucible having abrasive particles comprising a plurality of fine fibers, a plurality of abrasive particles, and a polymer. The fibers are staggered to form a fibrous substrate. The abrasive particles are attached to the fibers. The polymer ship coats the fibers and the abrasive particles. The invention further provides a method for manufacturing a polishing pad having abrasive particles, comprising the steps of: (a) providing a fibrous substrate having a plurality of fibers and a plurality of abrasive particles, wherein the fibers are staggered. The abrasive particles are attached to the fibers; (b) the fibrous substrate is impregnated into a polymer solution; and (c) a curing step is performed such that the fibrous substrate is coated with a polymer. Thereby, the flexibility of the fibers makes the abrasive grains less likely to scratch the surface of the workpiece to be polished, and the polishing pad only needs to have an acid solution without abrasive particles, a polishing solution or an electrolyte solution having an electrolyte. Auxiliary, there is a relatively good polishing ability, which can avoid the situation that the abrasive grains of the polishing liquid block the pores of the polishing pad in the prior art. In addition, after polishing with the polishing pad, the surface of the thrown 130536.doc 201016391 light workpiece has only a few abrasive grains remaining, which can be completed by a simple cleaning process, and is also easy to be used for wastewater treatment.

Group. Next, referring to step S92, a spinning step is performed to form the fiber material into a plurality of fibers 31, wherein a portion of the abrasive grains 32 are located inside the fibers 31, and a portion of the abrasive particles 32 are exposed. Preferably, the spinning step is a Melt Spinning, a Dry Spinning or a Wet Spinning as shown in FIGS. 7 and 8. In this embodiment, the fibers 3 are solid (as shown in Figure 7). In other applications, the fibers 3 can be hollow (as shown in Figure 8). Preferably, The fibers 31 are sized from Denier to 6 Danny. Preferably, the fibers 31 are selected from the group consisting of Polyamide Resin and polyethylene terephthalate. (Polyethylene Terephthalate, PET), p〇iyester Resin, Nylon, P〇lypr〇ylene (pp), Acrylic Resin and Resin group. Next, referring to step S93, a cotton making step is performed to form the fibers 31 into a fibrous substrate 34. In the present embodiment, the fibrous substrate 34 is a nonwoven fabric. Preferably, the fibrous substrate 34 is formed by chemical bonding, hot melt bonding, mechanical complexing, dry carding, direct forming or wet forming. Next, referring to step S94, the fibrous substrate 34 is impregnated into a localized molecular solution (not shown). 130536.doc -12- 201016391 Finally, the reference step S95 'peer-curing step' causes the woven substrate 34 to be covered by a polymer body 33 comprising a first surface 331 and a second surface 332. Preferably, a portion of the fibers 31 and a portion of the abrasive particles 32 are exposed on the first surface 331 of the polymer body 33.

The first surface 331 is a polished surface. The advantages of the present invention are as follows: during the polishing process, due to the flexibility of the fibers 21, 31 themselves, the fibers 21, 31 exposed on the first surface 231331 will follow the flow of the slurry or the polishing pad 2, 3, the vibration between the workpiece and the workpiece being oscillated, causing the abrasive particles 22, 32 attached thereto to move, and not always fixed at the same position, whereby the abrasive particles 22, 32 are not easily damaged. The surface of the workpiece being polished. Moreover, the polishing pad 2, 3 only needs to be assisted by an acidic, alkaline polishing liquid or an electrolyte solution having an electrolyte without abrasive particles, and has a relatively good polishing ability, thereby avoiding the polishing liquid in the prior art. The abrasive particles block the pores of the polishing pad. Further, after polishing with the polishing pad 2, 3, only a small amount of abrasive grains 22, 32 remain on the surface of the workpiece to be polished, which can be completed by a simple cleaning process, and is also easy to be used for wastewater treatment. The invention is illustrated by the following examples, which are not intended to be construed as limiting the invention. 130536.doc • 13· 201016391 Example: The manufacturing method of the present example corresponds to the manufacturing method of the second embodiment described above.
