Pure wool yarns may be produced on either the woollen or worsted system of manufacture. To the uniformed both will be described as woollen yarns. A distinction must, however, be made between end products produced from either woollen spun yarns or worsted spun yarns. Woollen simply relates to something to do wool. Woollen spun as well as worsted spun materials have a character of their own.
