Description
D01H covers mechanical processes and apparatus for spinning fibres into yarn or twisting multiple yarns together. This classification encompasses conventional spinning methods (ring spinning, open-end spinning, friction spinning) and modern techniques applied to natural fibres (cotton, wool, silk) and man-made fibres (synthetic and regenerated). It includes machinery components such as spindles, drafting systems, and twist insertion mechanisms, as well as process control methods for yarn production. Adjacent classifications address fibre preparation (D01C-D01G) and yarn finishing/treatment (D01D, D02).
