Abstract
A novel yarn is a bundle of multifiliment supply yarns, preferably at least two, with two alternating lengths in a selected ratio. The first length has alternating sections of entangled filaments forming nodes and unentangled, crimped filaments alternating in closely, substantially randomly-variable spaced sequence. The second length has substantially unentangled crimped filaments. The yarn is characterized by substantially uniform, linear denier and the extent of the second length from node to node is greater than the extent from node to node of any of the second sections of the first length. The yarn presents a space-dyed appearance, especially when multicolored supply yarns are employed, combined with varying textural, effects. Fabrics made of such yarns have novel and pleasing aesthetics. Novel apparatus for making the yarn is taught.
