OPTICAL METHOD FOR EVALUATING SURFACE AND PHYSICAL PROPERTIES OF STRUCTURES MADE WHOLLY OR PARTIALLY FROM FIBERS, FILMS, POLYMERS OR A COMBINATION THEREOF

摘要

Optical methods for evaluating various surface and physical optical properties of structures made wholly or partially from fibers, polymers, films or a combination thereof. Such methods are comprised of special illumination, special software algorithms and controls that provide a unique solution for evaluating such properties as fiber orientation distribution function, basis weight uniformity, fuzz and pilling, texture, and other physical and surface properties.
