Using Light and Scanning Electron Microscopic Methods to Differentiate Ibex Goat and Tibetan Antelope Fibers

Abstract

The scanning electron microscope is able to provide excellent differentiation between endangered Tibetan antelope and currently used Ibex goat hair fibers for "Shahtoosh" shawls. Although there are differences in the features of the fine hair fibers from these animals, the best differentiation is accomplished by using the significant differences found in the guard hair fibers that are inextricably mixed with the softer, smaller diameter hairs. The larger diameter antelope guard hairs have extremely thin walls, a cuticle structure, and a unique scale pattern that is totally different from those of the Ibex goat. Some of this important information is not as vividly apparent in a light microscope study.
