ABSTRACT OF THE DISCLOSURE A novel bulkable filamentary yarn having a flat yarn- like smooth appearance is disclosed, the bulkable filamentary yarn being composed essentially of bulkable portions and interlaced portions occurring alternately along the yarn length. Upon scouring, for example, the yarn develops its latent bulkiness similar to the fullness of silk and thus a silk-like appearance as well as a silk-like hand are provided in a fabric made from the yarn. The yarn itself can be obtained by heat-shrinking arc- like loops protruding from the yarn surface into a straightened state parallel to the yarn while the yarn is being tensioned along its length.
