ABSTRACT:
Process and apparatus for producing an interlaced multifilament yarn having a balanced compactness and bulkiness, composed of compact and open portions alternately appearing along its length, the compact portions having a fairly uniform configuration of interlacement. The yarn is prepared by bringing a running bundle of filaments in contact with two bending members for bending the thread-line so as to fix the thread-line between them and interlacing the filaments with an air jet as they pass between the bending members while forming such a stabilized thread-line.
