Abstract: A bulked and entangled multifilament thermoplastic yarn and an improved process for the formation thereof which, when tufted into a fabric, presents a grass-like appearance. The yarn is made by melt spinning and water quenching filaments of a melt spinnable synthetic organic thermoplastic polymer, such as polypropylene, in a continuous process, drawing the filaments, imparting bulk and entanglement in a fluid jet entangling mechanism and taking up the thus entangled yarn on a yarn winder. Also disclosed is an improved fluid jet entangling mechanism employed in the process.

Abstract: An improved yarn supply package comprising a yarn package holder is provided with a first yarn waste bunch wound on the package holder at one end portion thereof and a second yarn waste bunch connected to the first waste bunch and wound on the package holder intermediate the first waste bunch and the opposite end portion of the package holder. A main yarn package is wound on the package holder a distance from the second yarn waste bunch and is connected thereto by a yarn transfer tail. A power cylinder-actuated yarn tailing mechanism and a control system for the automatic control of the operation of the tailing mechanism is disclosed wherein the rod end of the cylinder carries a first tailing pin for guiding the initial windings of yarn on the package holder to form the first yarn waste bunch. A second tailing pin is carried by a tailing pin head and is supported adjacent the piston rod so that it moves along a line parallel to the axis of the piston rod.
