A continuous filament yarn that has been processed to introduce durable crimps, coils, loops or other fine distortions along the lengths of the filaments.

A yarn that has been so processed as to introduce durable crimps (q.v.), coils, loops or other fine distortions along the length of the fibres or filaments. NOTE: a) The main texturing processes usually applied to continuous-filament yarns made from or containing thermoplastic fibres, are as follows: 1. The yarn is highly twisted, heat-set and untwisted, either as a continuous process (false twisting) or as a three-stage process. 2. The yarn is passed through a heated "stuffer box" (stuffer box crimping). 3. The heated yarn is passed over a knife edge (edge crimping). 4. The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). 5. The yarn is knitted into a fabric, heat-set and unravelled (knit-deknit). 6. Loops are formed in individual filaments by over-feeding into a turbulent airstream (air-textured). 7. Bicomponent Fibres (q.v.) are differentially shrunk. b) Processes (1) and (3) above produce yarns of a generally high stretch character. This stretch character is frequently reduced by reheating the yarn in a state where it is only partly relaxed from the fully extended condition, thus producing a yarn with the bulkiness little reduced but with a much reduced retractive power. c) Fabrics that contain textured yarns have increased bulk, opacity, and moisture absorbency and improved thermal insulation properties with a warmer handle (q.v.); some textured yarns also confer extensible or "stretch" properties on fabrics made from them.

a general classification for continuous filament man - made fibre yarn which have been treated to give them hand and appearance which is different from the untreated yarn and / or stretchy. These yarns in some cases exhibit spun yarn effect. The yarns may be crimped ,curled, coiled, distorted through air jet process or given a false twist and then be heat set.
