Abstract: A randomly entangled, plied yarn having a first yarn strand and a second yarn strand wherein at least one of the first yarn strand or the second yarn strand is unidirectionally twisted in a first direction of twist, the plied yarn having spaced-apart spliced zones along its length defining therebetween lengths of unspliced yarn having a ply twist in the opposite direction of the twist of the component yarn strands along the entire length of the plied yarn.

Abstract: An apparatus for processing yarn, comprising yarn supply packages for supplying a yarn. First and second feed rolls and a take-up roll are provided for delivering the plied yarn from the supply package onto a take-up package. An air-jet is positioned between the first and second feed rolls for inserting short, spaced-apart entangled segments into the plied yarn as the plied yarn moves past the air-jet at a predetermined speed. The air-jet comprises an enclosure having a yarn entrance and a yarn exit and a nozzle for directing a stream of pressurized air into the enclosure and against the plied yarn while the plied yarn is moving through the enclosure. The nozzle moves past the enclosure at substantially the same surface speed as the yarn is moving through the enclosure whereby the stream of pressurized air impacts a short, discrete segment of yarn while the segment of yarn is within the enclosure.

Abstract: A winding apparatus which includes a plurality of yarn supply package stations for holding a plurality of packages of multifilament yarn, a processing station for receiving yarns from the yarn supply packages and processing the yarn, and a take-up package. The improvement comprises a yarn randomizing device positioned downstream from the supply packages and upstream from the processing station for intermixing filaments within a single yarn and among the plurality of yarns in a random and irregular manner before delivery of the yarns to the processing station thereby preventing patterning in the processed yarn, such as a rotating roller having threads thereon for reciprocating the yarns from one side of the roller to the other.
