A fabric fastener suitable for industrial use such as for fixing a porous working element to a rotor of a polisher, in which a male member has at least two groups of projections on one surface thereof, a first group having a hook or mushroom shape and a second group having a straight needle shape and a taller height than the projection of the first group, thereby the needle shape projection positively penetrates the interior of the porous mating member, while the hook or mushroom shape projection passively engages with a recess or a gap of the mating member, thus ensuring a proper engagement between both members.
