ABSTRACT:
Disclosed is a novel bulkable filamentary yarn of a flat yarn-like smooth appearance, said bulkable filamentary yarn is composed essentially of a bulkable portion and an interlaced portion existing alternately along the yarn length. Upon scouring, for example, said yarn develops its latent bulkiness similar to the fullness of silk, thus a silk-like appearance as well as a silk-like hand are provided in a fabric. The yarn itself can be obtained by heat-shrinking arc-like loops protruding on the yarn surface into a straightened state parallel to the yarn while the yarn is being tensioned along its length.
