length of textile material composed of spinnable fibres secured with a twist so that the rupture of the thread causes only the rupture of an individual fibre. May be of any length and fineness and is created by the spinning of fibres, which in the course of spinning settle so as to be of a certain quantity and in a certain order above and alongside each other. The slivers of fibre created are stabilized as y. by twisting. There are various spinning techniques, which are determined by the fibres used and their purpose. We distinguish between cotton y. (worsted, carded), flaxen and woollen y. (worsted, semi-worsted, carded), y. of natural silk, y. of chemical fibres, asbestos y.; and also between weaver's, hosier's, annular, self-actor and rotor y.
