ABSTRACT:
A non-twisted, heather yarn is formed of a plurality of major yarn bundles at least one of which is of a substantially different color from the remaining bundles. Each major yarn bundle is formed of a multiplicity of continuous filaments and has from about 10 to about 90 percent of its filaments cohering to form secondary bundles with the remaining filaments of each major bundle varying in number along the length of the yarn, being interlaced with other major bundles of the yarn, and being randomly located about the yarn axis. Each of the secondary bundles in each unit length of the yarn of about 6 inches has a portion thereof formed of greater than about 30 percent of the filaments of its major bundle and each of the secondary bundles in each unit length of yarn of about 8 inches is non-uniformly, differently oriented relative to the yarn axis.
