ABSTRACT:
A method and apparatus for modifying a spun yarn includes first storage or processing equipment for the yarn, subsequent storage or processing equipment for the yarn spaced some distance from the first storage or processing equipment, a path of travel for the yarn defined between the two sets of equipment, and a false untwister device located along said path of travel for imparting a false untwisting process to the yarn, the yarn subsequently reverting at least partly to the true twist originally present in the yarn, whereby the resulting yarn structure has a very much softer handle than was present prior to the false untwisting step.
