ABSTRACT:
A bulky textured multifilament yarn comprises sections of interlaced individual filaments and sections of non-interlaced individual filaments, wherein the interlaced and non-interlaced sections are formed alternately along the lengthwise direction of the yarn, the filaments in any predetermined length of the yarn are substantially identical in length, and some portions of the individual filaments protrude out from the axis of the yarn. The yarn is made by slackening a multifilament yarn treated by a false twisting operation, and then by interlacing the slackened multifilament yarn by means of a fluid jet stream while taking up the multifilament yarn.
