This document discusses different systems for measuring yarn count and properties. It defines units like denier, tex, and decitex that measure the weight of yarn over a specific length. The document also outlines the key processes involved in spinning fiber into yarn, including blowroom, carding, drawing, roving, and ring frame operations. Diagrams show the drafting zones in ring frames and different process flow sequences.
