Fibers are often tailored for their respective product using coatings. For example, absorbency or hydrophobicity can be built into fabrics using coated fibers. The surface roughness of individual fibers needs to be quantified for coating application. Optical profilometry is an ideal techniques for quantifying the roughness of surfaces.
In the paper industry, texture, tensile strength, surface roughness and fiber dimensions, as well as the thickness of ink layers and glossy coatings must all be considered when manufacturing paper. The Zeta-20 optical profiler quickly images and measures surfaces, including those with extreme differences in reflectance.
Using the optional 3D Roughness Reconstruction software, surface profiles and relative roughness measurements can be acquired with the Phenom desktop SEM.
