What refers to the fiber micron diameter of the wool?

The term that specifically refers to the fiber micron diameter of wool is fineness or grade. This measurement is crucial in the wool industry because it determines the quality of the wool produced. Fineness indicates how thin or thick the wool fibers are, which affects their usability in various textile applications. The finer the wool, measured in microns, the higher the quality and often the higher the market value. Grade, in this context, relates to the classification of wool based on its diameter and, consequently, its softness and thermal properties. Understanding fineness or grade helps sheep producers and wool processors make decisions regarding breeding and marketing strategies, as different markets may demand different fiber qualities. This directly ties into the economic viability of sheep farming and wool production.
