<p>An abrasive article having a multi-directional abrasion protrusion (120, 130, 220, 320, 330, 420, 520, 530, 620, 630) according to an exemplary embodiment of the present invention includes a flexible base substrate (110, 210, 310, 410, 510, 610), and a plurality of abrasion protrusions integrally molded with the base substrate and having at least three sides forming a triangle, in which a plurality of abrasion protrusions has a directional property by grouping. According to this constitution, loading resistance and durability are excellent, there are no attachment materials attached to an abraded surface in the case where a flat surface is abraded, abrasion can be efficiently and evenly performed in a predetermined shape even though abrasion particles are not enlarged to perform abrasion or abrasion is not repeated several times by using particulates, and abrasion performance can be improved.</p> |
