Czech encyclopedia entry on wool from Ottův slovník naučný, covering wool as the fleece of sheep, goats and camelids. It describes fibre structure under the microscope, fleece quality, the two main commercial classes (carding and combing wool), washing, shearing, sorting and grading by body region, goat and camelid fibres (cashmere, mohair, alpaca), and shoddy/mungo. It closes with a brief history, production statistics from the late 19th and early 20th centuries, and a bibliography. Illustrations show microscopic fibres and a sheep diagram of wool grades.
