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.

Bulked and entangled multifilament thermoplastic yarn

Method and apparatus for continuous formation of bulked and entangled

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. The second tailing pin guides the yarn to form the second yarn waste bunch and the yarn transfer tail. A mechanism interconnects the piston rod and the tailing pin head to move the second tailing pin along its guiding path.
