- the diameter of the abrasive particles may be changed as appropriate in accordance with the object to be ground, and, for example, may be from 0.1 to 1000 ⁇ .
- the circular nonwoven fabric 5 can be produced by, for example, impregnating a nonwoven fabric base material with a grind compound containing the abrasive particles, and drying and/or hardening.
- grind compound examples include the abrasive particles and a binder polymer such as epoxy resin, phenol resin, or the like, and a solvent such as xylene, carbitol, or the like, for dissolving the binder polymer, and, if necessary, a hardening agent may be included in the polishing compound. After impregnating this polishing compound in the nonwoven fabric base material, the solvent is removed and the binder polymer is hardened in, for example, a heating furnace, so that the polishing abrasive particles are retained on the nonwoven fabric base material.
- a binder polymer such as epoxy resin, phenol resin, or the like
- a solvent such as xylene, carbitol, or the like
- the circular nonwoven fabric 5 can be obtained by, for example, carrying out a punching process on the nonwoven fabric base material in a sheet form to obtain individual members with the shape illustrated in FIG. 3 . Also, the circular nonwoven fabric 5 can be obtained by causing the grind abrasive particles to be retained on the nonwoven fabric base material that has been processed to the shape illustrated in FIG. 3 or the like.
- the external diameter of the circular nonwoven fabric 5 can be for example, from 50 to 500 mm, or from 100 to 200 mm.
- the thickness of the circular nonwoven fabric 5 preferably, each of the plurality of circular nonwoven fabrics 5 have the same thickness, but they may have different thicknesses.
- the thickness of the circular nonwoven fabric 5 before stacking may be, for example, from 2 to 30 mm, or it may be from 5 to 20 mm.
- the outer layer (plate) 20 includes nonwoven fabric 2 that is hardened in the compressed state, and may be the same nonwoven fabric described above for the nonwoven fabric base material.
- the outer layer (plate) 20 can be obtained by, for example, stacking a plurality of sheets of nonwoven fabric 2 in a sheet form, hardening them while they are compressed in the stacking direction, and next a punching process is performed on the hardened nonwoven fabric to obtain individual members with the shape illustrated in FIGS. 4A , B. Also, the outer layer (plate) 20 can be obtained by stacking and compressing in the stacking direction a plurality of nonwoven fabric 2 that has been processed into the shape as illustrated in FIGS. 4A , B or the like.
- the outer layer (plate) 20 may be obtained by stacking a plurality of nonwoven fabric base material of the circular nonwoven fabric 2 , compressing it in the stacking direction, and hardening it, or the outer layer (plate) 20 may be obtained by stacking a plurality of the circular nonwoven fabrics 2 , compressing them in the stacking direction, and hardening it.
- the outer layer (plate) 20 includes a laminate that has been hardened while compressed in the stacking direction, and the laminate includes a plurality of stacked circular nonwoven fabrics.
- the number of the stacked circular nonwoven fabrics 2 in the laminate for example, it can be selected as appropriate in order to satisfy the preferred thickness as described later and the preferred deformation rate as described above.

- DICY dicyandiamide
- acid hydrazide boron trifluoride complex
- imidazole compound amine imide
- lead salts and, of these, dicyandiamide is particularly preferred.
- the nonwoven fabric included in the outer layer (plate) 20 is hardened by an adhesive, and a content of the adhesive is in a range from 5 to 30 mass % of the total mass of the nonwoven fabric.
- the outer layer (plate) 20 that includes such nonwoven fabric can easily satisfy the deformation rate as described above. Also, such the outer layer (plate) 20 can have a sufficiently large amount of wear in the polishing process, so it is possible to perform the polishing process more efficiently.
- FIGS. 5A and 5B are schematic cross-sectional views illustrating examples of a manufacturing process of the nonwoven fabric grind disc 100 .

- the circular nonwoven fabrics 2 and the circular nonwoven fabrics 5 that are stacked using the shaft 500 are retained at both ends in the stacking direction by a retaining fixture 600 .
- the retaining fixture 600 is provided with a through hole in the center into which the shaft 500 is inserted so that the retaining fixture 600 can move freely in the stacking direction.
- the circular nonwoven fabrics 2 and the circular nonwoven fabrics 5 are compressed in the stacking direction via the retaining fixture 600 using compression means 650 installed at one of the retaining fixtures 600 , to form the compressed laminate as illustrated in FIG. 5B .
