/yahrn/, n.1. thread made of natural or synthetic fibers and used for knitting and weaving.2. a continuous strand or thread made from glass, metal, plastic, etc.3. the thread, in the form of a loosely twisted aggregate of fibers, as of hemp, of which rope is made (rope yarn).4. a tale, esp. a long story of adventure or incredible happenings: He spun a yarn that outdid any I had ever heard.v.i.5. Informal. to spin a yarn; tell stories.[bef. 1000; ME; OE gearn; c. G Garn; akin to ON gorn gut, Gk chordé intestine, CHORD1, Lith zarnà entrails, L hernia a rupture, Skt hira vein]
* * *Continuous strand of fibres grouped or twisted together and used to construct textile fabrics.Yarns are made from both natural and synthetic fibres, in filament or staple form. Filament is very long fibre, including the natural fibre silk and the synthetic fibres. Most fibres that occur in nature are fairly short, or staple, and synthetic fibres may be cut into short, uniform lengths to form staple. Spinning is the process of drawing out and twisting a mass of cleaned, prepared fibres. Filament yarns generally require less twist than do staple yarns. More twist produces stronger yarn; low twist produces softer, shinier yarn. Two or more single strands may be twisted together to form ply yarn. Knitting yarns have less twist than weaving yarns. Thread, used for sewing, is a tightly twisted ply yarn.

For full treatment, see textile: Production of yarn (textile).Yarns are made from both natural and synthetic fibre, in filament or staple form. Filament is fibre of great length, including the natural fibre silk and the synthetic fibres. Most fibres that occur in nature are of fairly short length, or staple, and synthetic fibres may be cut into short, uniform lengths to form staple.spinning is the process of drawing out and imparting twist to a mass of fibres. Filament yarns generally require less twist than staple. A fairly high degree of twist produces strong yarn; low twist produces softer, more lustrous yarn; and tight twist produces crepe yarns. Two or more single strands of yarn may be twisted together, forming ply yarn.Novelty yarns, used to produce special effects, include bouclé, characterized by projecting loops; nub yarn, with enlarged places, or nubs, produced by twisting one end of a yarn around another many times at one point; and chenille, a soft, lofty yarn with pile protruding on all sides. Textured yarns are synthetic filament yarns that are made bulky or stretchy by heating or other techniques.In yarns used for weaving, the warp, or lengthwise, yarns are usually made stronger, more tightly twisted, smoother, and more even than the filling, or crosswise, yarns. Knitting yarns have less twist than weaving yarns. Yarns used for machine knitting may be single or ply types; ply yarns are generally used for hand knitting. Thread, used for sewing, is a tightly twisted ply yarn having a circular cross section.
