A multifilament yarn in which cohesion is imparted to the filament bundle by entwining the filaments instead of, or in addition to, twisting. The effect is usually achieved by passing under light tension through the turbulent zone of an air-jet.
Note 1: Some manufacturers describe such a product as an interlaced yarn.
Note2. Intermingling should be distinguished from air-texturing (see textured yam ) in which a much higher level of entanglement is achieved with the objective of producing texture or bulk
