  • Nonwoven abrasive material
    Patent number: 6860959
    Abstract: An abrasive material comprises an integral mass of discrete lengths, not bonded to each other, of abrasive-coated non-woven synthetic fibres. In particular, the entanglement force between the said lengths is great enough to maintain a wad of the material when in use but small enough to allow the product to be shaped in the hand of a user.
