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.
