What of the fleece is an estimate of the percentage of clean wool fibers obtained after the scouring process?

The estimate of the percentage of clean wool fibers obtained after the scouring process is known as yield. This term specifically refers to the proportion of usable wool that remains after the raw fleece undergoes cleaning and processing to remove grease, dirt, and other contaminants. The yield is a critical metric in wool production, as it directly impacts the overall quality and quantity of wool available for commercial use.

Understanding yield is vital for producers because higher yields indicate a more efficient cleaning process and better-quality raw material, which can lead to increased profitability. In contrast, finer details such as fineness, density, and mass pertain to different aspects of fleece characteristics, like the diameter of the wool fibers or the weight of the fleece, but do not directly represent the proportion of clean wool achieved through scouring.
