I am looking for a word describing a patchy appearance in something like hair, felt, grass, velvet etc- specifically surfaces, materials or areas comprised of a totality of much smaller, and usually upwardly angled fibers, hairs, blades and so forth, where there are areas of visible wear, damage or interruption. I've gone through the thesaurus ouroborus multiple times and cannot find the word I'm looking for. Any help would be appreciated!
having the nap worn off so that the thread shows
An animal with patchy fur may have mange and can be described as mangy, but mangy may also mean:
having many worn or bare spots a mangy rug
The word implies that the animal or item was once whole but has become patchy or scruffy-looking through disease or disrepair.
