Abstract

Nylon or polyethylene terephthalate yarn is subjected to a first drawing operation in which the mechanical draw ratio is less than the natural draw ratio of the yarn at the drawing temperature so that, repeatedly, a localised drawing point or "neck" is formed along the length of the yarn at which the denier falls off with distance in the direction of advance of the yarn and that migrates in the direction in which the yarn is advancing, and yarn withdrawn from the first drawing operation which has relatively undrawn regions alternating with relatively drawn regions is then subjected to a second drawing operation in which the mechanical draw ratio is sufficiently low to avoid excessive breaking of the yarn or its constituent filaments. The yarn from the second drawing operation may be dyed with a dye that is sensitive to differences in the degree of molecular orientation in the yarn polymer to give the yarn a variegated appearance, alternatively it may be dyed with a disperse dye which is insensitive in this respect.
