The Identification of Specialty Fibers

Because specialty fibers are expensive and are often blended with wool, there is a need to be able to distinguish between the two groups. Certain lustrous wools are even in diameter and have long scales like mohair, but there are visible differences in scale thickness and brightness. Cashmere and camel hair are fine and somewhat uneven in diameter, cashmere having wide scales and camel almost convex ones. Alpaca and Angora rabbit fibers have distinctive scale and medulla features of their own.
