Abstract
A novel yarn is a bundle of multifilament continuous supply yarns with two sequentially alternating lengths in a preselected ratio. The first length has alternating sections of entangled filaments and unentangled, crimped filaments alternating in closely, substantially randomly-variably spaced sequence. The second length has substantially unentangled, crimped filaments. The yarn has substantially uniform linear denier and the extent between nodes of the second length is greater than the extent between nodes of any of the second sections of the first length. The yarns made present a space dyed appearance, especially when multicolored supply yarns are employed, combined with varying textural effects. Apparatus for making the yarn has a source of crimped yarn, a transport for forwarding the supply yarn as a bundle, an entangling jet connected via a valve to pressurized fluid at a level to entangle yarn in the jet, programmed timed valve-sequencing to alternate the fluid supply to the jet between a yarn entangling condition and a nonentangling condition in a manner producing the novel yarn, and yarn overfeed transport and take-up means.
