To provide a consistent outflow of light, the abrasive method involves utilizing an abrasive substance to produce mechanical surface flaws in the fibre. Abrasives may be sprayed on the surface to be abraded, or mechanical tools (such as a knife or sandpaper) may be used (sanding, etc.). For instance, by creating brilliant reflections at the fibre edges, the latter treatment of the fibres, most notably by sanding, produces patterns.

By modifying the optical sheath’s surface, making “micro-perforations” or rough patches, using an abrasive, producing surface flaws, and allowing light to leak out along the fibres, it is possible to change the way that optical fibres conduct light. The original optical fibre then transmits the light radiation from one end of the fibre to the other while according to the laws of waveguides.

The luminous surface flux is maintained constant by administering a progressive treatment along the optical fibres, which is confirmed by observing the radiation that can be seen on the fabric.

NextGen’s Akron Abrasion Tester is especially suited for testing harder materials such as shoe soles, tires and other rubber materials.
