<p>A multifilament thermoplastic yarn and process for the ormation thereof which, when tufted or woven into a fabric, presents a grass-like appearance. The yarn is made by neltspinning (18, 20) and water quenching (24), a melt-spinnable synthetic organic thermoplastic polymer, such as polypropylene, drawing the filaments, surface heating at east a portion of the thus drawn filaments (30, 50) cooling the thus surface heated filaments and reheating the thus ooled filaments either before or after tufting, weaving or otherwise processing into a fabric to develop latent crimp in the yarn. Also disclosed is a carpet fabric employing the yarn and exhibiting grass-like appearance with exceptional cover and relatively soft hand.</p> |
