The present invention provides a method and apparatus for forming a textured air jet interlaced yarn comprising a plurality of continuous synthetic thermoplastic filaments, the yarn being characterized by repeating sections of about 1/8-1" in length, each section being composed of a relatively open portion of bulky and lofty false twisted multifilaments and a relatively short node portion where the multifilaments are brought closer together and are interlaced and encircled. The yarn is prepared by passing a yarn through texturing means whereby the yarn is false twisted and heat set in the twisted condition, passing the textured yarn through an air jet where the air is fed into the yarn at an angle of 45-75.degree. and passed cocurrently through the jet with the yarn to interlace the yarn and then collecting the textured, interlaced yarn. Texturing apparatus for performing the method and forming the textured yarn is also provided.
