Abstract

A substantially lofty non-woven fabric abrasive material includes: a non-woven fabric composed of randomly arrayed fibers; an adhesive agent adhered to the fibers of the non-woven fabric; and abrasive particles adhered to the non-woven fabric by the adhesive agent; wherein the abrasive particles contain soft large-sized particles and hard small-sized particles.

Claims

1. A substantially lofty non-woven fabric abrasive material comprising:

a non-woven fabric composed of randomly arrayed fibers;

an adhesive agent adhered to the fibers of the non-woven fabric; and

abrasive particles adhered to the non-woven fabric by the adhesive agent;

wherein the abrasive particles contain soft large-sized particles and hard small-sized particles.

2. A non-woven fabric abrasive material according to claim 1, wherein a particle diameter of said soft large-sized particles is 10 to 1000 times a particle diameter of said hard small-sized particles.

3. A non-woven fabric abrasive material according to claim 1, wherein an average particle diameter of said soft large-sized particles is 0.1 to 1 mm and an average particle diameter of said hard small-sized particles is 1 to 10 μ

m.

4. A non-woven fabric abrasive material according to claim 1, wherein a Mohs hardness of said soft large-sized particles is 2 to 4 and a Mohs hardness of said hard small-sized particles is 8 or more.

5. A non-woven fabric abrasive material according to claim 1, wherein a Mohs hardness of said adhesive agent is the same as a Mohs hardness of said soft large-sized particles.

6. A non-woven fabric abrasive material according to claim 1, wherein combination ratio of the soft large-sized particles and the hard small-sized particles is in the range of from 1:

9 to 9;
